1 00:00:08,320 --> 00:00:11,360 DOUGAL JERRAM: My first impressions of when I arrived at Pompeii was 2 00:00:11,520 --> 00:00:14,120 surprise at the scale of the city. 3 00:00:17,280 --> 00:00:22,360 You can see streets, columns, statues. 4 00:00:23,280 --> 00:00:26,320 It really was clearly a vibrant place. 5 00:00:28,040 --> 00:00:32,840 And yet you look to one side and it stares you in the face. 6 00:00:34,520 --> 00:00:35,680 There's the volcano, 7 00:00:37,000 --> 00:00:40,920 Mount Vesuvius, shadowing over the whole area. 8 00:00:43,040 --> 00:00:45,520 These people were living by this mountain, 9 00:00:45,600 --> 00:00:48,040 and this mountain ended up being their doom. 10 00:00:51,280 --> 00:00:52,440 (EXPLODES) 11 00:00:57,360 --> 00:01:00,760 The destruction of Pompeii has really captured people's imagination. 12 00:01:01,600 --> 00:01:03,240 Particularly with the preserved bodies. 13 00:01:04,720 --> 00:01:09,120 Thousands frozen in time at the very moment of a horrifying death. 14 00:01:10,720 --> 00:01:14,600 But what's really quite surprising is when they uncovered the town of Herculaneum, 15 00:01:15,600 --> 00:01:18,400 the town much closer to the volcano than Pompeii, 16 00:01:19,320 --> 00:01:22,840 they found very, very few bodies, and that's a really intriguing question. 17 00:01:24,720 --> 00:01:27,680 Why so few bodies in Herculaneum, 18 00:01:27,800 --> 00:01:29,480 and why so many in Pompeii? 19 00:01:38,920 --> 00:01:41,600 DR. LUANA TONIOLO: It was not just an excavation, 20 00:01:41,680 --> 00:01:43,600 but something like a detective story. 21 00:01:44,720 --> 00:01:46,400 It was really incredible. 22 00:01:49,600 --> 00:01:52,240 PIER PAOLO PETRONE: I saw hundreds of skeletons. 23 00:01:53,320 --> 00:01:54,360 Who were these people? 24 00:01:55,200 --> 00:01:56,640 And how did they die? 25 00:01:58,640 --> 00:02:00,800 JERRAM: On the flanks of this fearsome volcano, 26 00:02:00,880 --> 00:02:03,440 what really was the key to life and death? 27 00:02:23,440 --> 00:02:25,840 REPORTER 1: Pompeii archaeologists made the discovery 28 00:02:25,920 --> 00:02:28,960 of what they term as "an exceptionally rare find." 29 00:02:29,040 --> 00:02:31,920 REPORTER 2: This is the latest in a series of fascinating discoveries 30 00:02:32,000 --> 00:02:35,000 that excavations at Pompeii have yielded in recent years. 31 00:02:41,280 --> 00:02:42,560 (TONIOLO SPEAKING) 32 00:03:35,880 --> 00:03:38,200 DR. GABRIEL ZUCHTRIEGEL: What's special in Pompeii 33 00:03:38,280 --> 00:03:39,520 is that you're looking 34 00:03:39,600 --> 00:03:42,760 not at single works of art, 35 00:03:43,320 --> 00:03:47,840 or not even single monuments, that it's all part of a city. 36 00:03:48,720 --> 00:03:52,400 And a city that was inhabited by people. 37 00:03:58,600 --> 00:04:03,280 I started to study archaeology because I was interested 38 00:04:03,720 --> 00:04:06,160 not so much in ancient art, but in history. 39 00:04:06,240 --> 00:04:07,240 So how did people live? 40 00:04:08,960 --> 00:04:12,960 There was one discovery that sparked interest around the world. 41 00:04:14,600 --> 00:04:18,200 It was really something very, very extraordinary. 42 00:04:26,320 --> 00:04:31,280 It all started with the police discovering an underground network of tunnels. 43 00:04:34,560 --> 00:04:36,720 Tomb raiders broke through the wall, 44 00:04:36,840 --> 00:04:40,800 searching for precious objects and wall paintings 45 00:04:41,200 --> 00:04:46,280 to take away and sell them on the illegal market for antiquities. 46 00:04:48,080 --> 00:04:51,320 They were caught in action and the excavation started. 47 00:04:54,520 --> 00:04:57,440 Outside the city of Pompeii, there are many villas, 48 00:04:57,520 --> 00:05:00,280 but many of them had been excavated illegally. 49 00:05:01,880 --> 00:05:08,600 So this is a great opportunity to do a scientific excavation of such a site. 50 00:05:11,600 --> 00:05:16,680 The villa was first excavated in the early 20th century, 51 00:05:16,760 --> 00:05:21,400 but we had an extremely fragmented view of this site 52 00:05:21,760 --> 00:05:27,600 and actually didn't really know the importance of the villa until 2017. 53 00:05:33,120 --> 00:05:35,440 Nothing prepared us for what we would discover. 54 00:07:36,360 --> 00:07:40,120 ZUCHTRIEGEL: While the organic material were dissolving, 55 00:07:41,320 --> 00:07:43,760 the imprints remained in the soil, 56 00:07:43,880 --> 00:07:47,560 and now as we, as archaeologists, come across this, 57 00:07:47,640 --> 00:07:51,720 we know it's important to stop excavating, 58 00:07:51,800 --> 00:07:54,200 and we fill it with plaster. 59 00:07:54,360 --> 00:07:56,640 The technique of the plaster casts 60 00:07:56,720 --> 00:08:01,600 allows us to reconstruct that which is not there anymore. 61 00:08:03,560 --> 00:08:08,920 Then we get the imprint of animals, and sometimes also humans. 62 00:09:06,440 --> 00:09:09,720 ZUCHTRIEGEL: The new excavations continued there 63 00:09:09,800 --> 00:09:12,160 and started to bring to light 64 00:09:12,240 --> 00:09:14,360 something we'd never seen before. 65 00:09:27,080 --> 00:09:31,080 It was of an extraordinary luxury, 66 00:09:33,600 --> 00:09:37,120 with decoration in gold and silver and bronze. 67 00:09:40,760 --> 00:09:43,200 It was a really incredible chariot. 68 00:09:47,880 --> 00:09:49,400 It was really a great surprise. 69 00:09:52,760 --> 00:09:54,840 But right next to it, there was a room 70 00:09:54,920 --> 00:09:59,360 which really, for me, is maybe the most touching 71 00:09:59,440 --> 00:10:03,480 and moving discovery I've made as an archaeologist. 72 00:10:11,240 --> 00:10:15,200 This was a part of the villa which was formerly totally unknown. 73 00:10:18,760 --> 00:10:23,320 There's no treasury here in terms of gold and silver and precious vases. 74 00:10:24,560 --> 00:10:27,800 But what is really special about this room 75 00:10:27,880 --> 00:10:32,640 is that we have the plaster casts of three beds. 76 00:10:35,040 --> 00:10:39,080 But they are really simple, simple beds. 77 00:10:40,920 --> 00:10:42,480 Very ordinary. 78 00:10:50,920 --> 00:10:54,120 DR. SOPHIE HAY: When I heard about the discovery of that room in the villa, 79 00:10:54,200 --> 00:10:55,800 I knew it was something special. 80 00:10:57,480 --> 00:10:59,880 Nothing like this has been found before. 81 00:11:02,080 --> 00:11:05,160 When I arrived in Pompeii, I had obviously seen photographs, 82 00:11:05,240 --> 00:11:08,480 but there's nothing quite like arriving on site. 83 00:11:09,880 --> 00:11:13,200 It felt about as close as you could to time travel. 84 00:11:22,040 --> 00:11:25,320 So this is a really unusual scene to witness. 85 00:11:26,560 --> 00:11:29,240 This is the small room just near the stable. 86 00:11:30,360 --> 00:11:31,960 I mean, you can see how cramped it is. 87 00:11:33,280 --> 00:11:37,160 We expect there to be great wealth in these suburban villas, 88 00:11:37,240 --> 00:11:42,280 and here we see a room with bare walls, a bit of white plaster, very simple. 89 00:11:44,320 --> 00:11:46,080 There's no mosaics on the floor. 90 00:11:46,160 --> 00:11:48,360 It sort of seems like it's just packed earth. 91 00:11:49,080 --> 00:11:51,000 So, it's sort of a little bit of a mystery 92 00:11:51,080 --> 00:11:54,680 as to what this room was because it's... 93 00:11:55,400 --> 00:11:58,920 Doesn't really fit our picture of a lavish suburban villa. 94 00:12:04,680 --> 00:12:06,880 Not the elite part of the house at all. 95 00:12:07,920 --> 00:12:10,840 We're looking at very much a sort of a working room, 96 00:12:10,920 --> 00:12:12,360 a service room, if you like. 97 00:12:14,760 --> 00:12:20,240 They brought amphoras, and this is a steering mechanism, 98 00:12:20,360 --> 00:12:23,880 probably from the chariot found in front of the door. 99 00:12:24,680 --> 00:12:27,080 And then you have all kinds of materials 100 00:12:27,160 --> 00:12:30,800 from the bridle and things linked to the horses. 101 00:12:31,240 --> 00:12:34,240 So, it was a workplace, but it was also a living place. 102 00:12:38,360 --> 00:12:42,880 What we see here is really the most humble level of society. 103 00:12:46,680 --> 00:12:48,600 So it probably was a slave room. 104 00:12:50,520 --> 00:12:54,280 And there were at least three slaves living here, sleeping here. 105 00:12:58,760 --> 00:13:01,520 HAY: It's an absolutely incredible find. 106 00:13:02,800 --> 00:13:05,320 These are the invisible people in the Roman period. 107 00:13:07,080 --> 00:13:09,000 It's quite emotional, looking at and seeing, 108 00:13:09,080 --> 00:13:11,600 feeling so close to their lives. 109 00:13:13,960 --> 00:13:17,160 One third of the population were probably enslaved people. 110 00:13:18,560 --> 00:13:23,680 Their jobs would range from shopkeeping to sex work. 111 00:13:24,040 --> 00:13:26,080 So we've got a lot of range here. 112 00:13:26,160 --> 00:13:28,840 But then suddenly we get this magnifying glass 113 00:13:28,960 --> 00:13:30,880 of their lives at this villa. 114 00:13:32,480 --> 00:13:34,240 There's three beds in the room. 115 00:13:34,520 --> 00:13:37,800 One of the beds is slightly smaller than the other two, suggesting 116 00:13:37,920 --> 00:13:42,600 maybe there was a child, so it could have been a family unit of enslaved people. 117 00:13:47,320 --> 00:13:50,360 At this point, the excavation hadn't found any bodies. 118 00:13:51,120 --> 00:13:54,040 So everyone is wondering what happened to the inhabitants. 119 00:13:57,240 --> 00:13:58,520 (TONIOLO SPEAKING) 120 00:17:05,680 --> 00:17:09,200 This villa really presents us with a sort of detective story, 121 00:17:09,280 --> 00:17:11,360 which is essentially what archaeology is. 122 00:17:13,280 --> 00:17:16,440 So this image is really important because it gives you a real sense 123 00:17:16,520 --> 00:17:19,360 of the context in which these two people were found. 124 00:17:21,200 --> 00:17:24,680 They've basically gone down to the lowest point 125 00:17:24,800 --> 00:17:27,640 they could in the villa, in the cryptoporticus, 126 00:17:27,720 --> 00:17:29,600 so it's an underground passage. 127 00:17:31,760 --> 00:17:34,120 It shows how desperate they must have been 128 00:17:34,200 --> 00:17:38,240 at the time to take shelter and cover from the eruption. 129 00:17:41,040 --> 00:17:44,040 Clearly, sheltering here provided no protection. 130 00:17:44,760 --> 00:17:47,160 So the big question is, how did they die? 131 00:17:52,800 --> 00:17:55,680 JERRAM: The only way to find out what happened in the villa 132 00:17:55,760 --> 00:17:58,840 is to work out how the volcanic eruption unfolded. 133 00:18:04,800 --> 00:18:08,440 Witnessing an eruptive volcano is really an assault on the senses. 134 00:18:12,520 --> 00:18:15,400 It's terrifying, but also mesmerizing. 135 00:18:21,520 --> 00:18:24,480 When I first went to Vesuvius, I was really hooked from day one. 136 00:18:30,160 --> 00:18:33,280 It turns out there's some really tantalizing details in one letter, 137 00:18:34,960 --> 00:18:37,640 written by a man called Pliny the Younger, a Roman, 138 00:18:37,720 --> 00:18:39,120 to an historian friend of his. 139 00:18:39,200 --> 00:18:43,080 He witnessed the eruption, and according to Pliny's letters, 140 00:18:43,320 --> 00:18:45,200 the eruption started around midday. 141 00:18:47,480 --> 00:18:50,920 You almost get a picture of what it must have been like just seconds before. 142 00:18:51,800 --> 00:18:52,840 And bang! 143 00:18:55,080 --> 00:18:59,960 He says, "Tall, broad flames blazed from several places on Vesuvius 144 00:19:00,520 --> 00:19:02,400 "and glared out through the darkness. 145 00:19:03,920 --> 00:19:05,880 "It was daylight everywhere else, 146 00:19:05,960 --> 00:19:08,760 "but it was blacker and denser than any night. 147 00:19:10,120 --> 00:19:13,320 "After a while, the darkness paled into smoke, 148 00:19:14,200 --> 00:19:17,520 "but the sun shone as wanly as during an eclipse." 149 00:19:22,400 --> 00:19:26,720 What we've been realizing, particularly from the way Pliny described it, 150 00:19:27,520 --> 00:19:33,440 it was almost sort of 20, 24 hours worth of process that went on. 151 00:19:35,600 --> 00:19:38,640 The very first stage was this big explosive phase. 152 00:19:45,000 --> 00:19:49,240 And that immediately sent up this "strange cloud," as Pliny described it. 153 00:19:50,920 --> 00:19:54,120 Big column of material that went high up into the atmosphere. 154 00:19:58,440 --> 00:20:02,880 What Pliny doesn't tell us is exactly what happened next inside Pompeii, 155 00:20:03,760 --> 00:20:06,320 and also the other towns around Vesuvius. 156 00:20:08,080 --> 00:20:11,360 But luckily, the volcano has left its own detailed record 157 00:20:11,960 --> 00:20:15,160 of the events on that day, and I'm going to dig into it. 158 00:20:32,840 --> 00:20:37,000 I really wanted to see whether the eyewitness accounts actually match up 159 00:20:37,080 --> 00:20:40,520 with the deposits and the debris that we see that buried the towns. 160 00:20:41,160 --> 00:20:43,880 And it's by doing this that we can hopefully start to pinpoint 161 00:20:43,960 --> 00:20:46,520 what happened during the eruption, hour by hour. 162 00:20:52,560 --> 00:20:54,680 At the southern tip of Pompeii, 163 00:20:55,400 --> 00:20:59,040 this spot is one of the few places left where you can still see 164 00:20:59,160 --> 00:21:01,280 some of the layers of the volcanic deposits. 165 00:21:03,080 --> 00:21:05,800 When people think of volcanoes, they often think of these sort of 166 00:21:05,880 --> 00:21:09,600 mesmerizing red lava flows making their way down the mountain. 167 00:21:10,240 --> 00:21:13,640 But actually, that didn't happen with the Mount Vesuvius eruption. 168 00:21:14,600 --> 00:21:16,720 What we see in the different parts of the layers 169 00:21:16,800 --> 00:21:19,840 tell us something about how the eruption took place. 170 00:21:21,400 --> 00:21:23,840 And when we start to look at the deposit, 171 00:21:23,920 --> 00:21:28,080 I mean, you can see the first sort of a couple of meters here, 172 00:21:28,600 --> 00:21:30,520 things aren't really being destroyed. 173 00:21:30,600 --> 00:21:35,040 All of these pots are totally as they were standing around at the time. 174 00:21:35,520 --> 00:21:39,240 And that's because all of this deposit here is what we call the "fall deposit." 175 00:21:39,320 --> 00:21:41,440 It's stuff that was coming out of the sky. 176 00:21:43,280 --> 00:21:46,120 It first started with this, what we call white pumice. 177 00:21:46,200 --> 00:21:50,720 So this very, very light material was raining out of the sky 178 00:21:50,800 --> 00:21:54,720 from this big cloud, this big eruptive cloud that Pliny described. 179 00:22:00,920 --> 00:22:03,640 And when we try and sort of unravel the timeline here, 180 00:22:04,000 --> 00:22:08,360 essentially from where my feet are, up until this change 181 00:22:08,440 --> 00:22:11,480 from this sort of white pumice to the gray pumice, 182 00:22:12,200 --> 00:22:15,360 this represents the volcano sort of starting 183 00:22:15,440 --> 00:22:18,600 about 1:00 in the afternoon, up until round about midnight. 184 00:22:34,080 --> 00:22:36,680 Clearly it's a very strange environment to be in. 185 00:22:36,760 --> 00:22:39,440 It's like a snowstorm, but it would be really dark. 186 00:22:39,760 --> 00:22:42,320 You've got ash floating around in the air. 187 00:22:42,960 --> 00:22:44,240 There may be fires started 188 00:22:44,320 --> 00:22:46,240 by some of the hotter material that's landing. 189 00:22:46,320 --> 00:22:48,040 Quite a terrifying experience. 190 00:22:51,360 --> 00:22:54,440 It's difficult to imagine what it would be like being caught up in this. 191 00:22:55,880 --> 00:22:57,320 How do you survive it? 192 00:22:59,800 --> 00:23:02,960 When it starts raining these pumice stones, 193 00:23:03,040 --> 00:23:06,920 the natural reaction is just to search cover somewhere. 194 00:23:09,520 --> 00:23:11,520 This becomes a deadly trap. 195 00:23:13,480 --> 00:23:18,560 People can't get out of the doors anymore because they are blocked by pumice stones. 196 00:24:37,960 --> 00:24:41,720 One of the things that's really striking is just the visual difference 197 00:24:41,800 --> 00:24:43,880 between the layers here. 198 00:24:46,040 --> 00:24:49,040 You can actually see one on top of another, some of them 199 00:24:49,200 --> 00:24:53,840 almost like a stack of cards, showing you that there's a sideways movement. 200 00:24:54,640 --> 00:24:58,240 There's a current, there's a turbulent current that's deposited this here. 201 00:25:00,440 --> 00:25:03,600 It tells us that something back at the volcano was changing. 202 00:25:04,960 --> 00:25:07,920 This huge column of rock and ash that was bursting 203 00:25:08,040 --> 00:25:10,080 its way up into the sky has now collapsed. 204 00:25:14,280 --> 00:25:20,600 And you've got a dense, turbulent current of rocks, hot pumice and ash, hot gases, 205 00:25:20,960 --> 00:25:24,360 all rolling over each other and barreling down the side of the mountain. 206 00:25:24,840 --> 00:25:27,480 These things can be hundreds of degrees in heat, 207 00:25:27,800 --> 00:25:30,200 and they can travel hundreds of miles an hour. 208 00:25:30,960 --> 00:25:32,960 It's engulfing things as it goes along. 209 00:25:33,960 --> 00:25:35,320 This is a pyroclastic flow. 210 00:25:38,840 --> 00:25:40,840 The whole thing is chaotic. 211 00:25:43,960 --> 00:25:47,360 It's a kind of angry stage in the eruption from this stuff falling 212 00:25:47,440 --> 00:25:50,800 out of the sky to all of a sudden the pyroclastic flow coming in 213 00:25:51,280 --> 00:25:53,560 and essentially just taking everything in its wake. 214 00:25:59,520 --> 00:26:05,160 So many stories. People trying to escape outside Pompeii, some hiding. 215 00:26:06,560 --> 00:26:12,360 And so those who did what seemed probably the wrong thing in the first moment, 216 00:26:13,280 --> 00:26:16,640 to go through the rain of stones, 217 00:26:17,600 --> 00:26:21,280 had probably the biggest chance to survive. 218 00:26:23,320 --> 00:26:26,440 Those who stayed behind went right to their death 219 00:26:26,520 --> 00:26:29,600 because there was no escape from the pyroclastic flow. 220 00:26:34,720 --> 00:26:36,800 JERRAM: The devastation that was seen at Pompeii 221 00:26:36,880 --> 00:26:38,640 has really captured people's imaginations, 222 00:26:38,720 --> 00:26:40,920 particularly with the body molds that are preserved. 223 00:26:41,000 --> 00:26:42,320 Thousands of people dying. 224 00:26:47,000 --> 00:26:48,720 One of the things that's really puzzling 225 00:26:48,800 --> 00:26:51,240 is that you've got lots of bodies preserved at Pompeii, 226 00:26:51,960 --> 00:26:54,960 but closer to Mount Vesuvius in Herculaneum, 227 00:26:55,040 --> 00:26:57,040 another place smothered by the eruption, 228 00:26:57,600 --> 00:27:00,760 when they uncovered the city, they found very, very few bodies. 229 00:27:02,880 --> 00:27:06,240 So the big question is, why was it so different there? 230 00:27:24,080 --> 00:27:26,200 PETRONE: Pompeii is very famous all over the world. 231 00:27:26,880 --> 00:27:32,720 But in the '90s, I had the opportunity to excavate victims in Herculaneum. 232 00:27:37,000 --> 00:27:41,000 Mostly, anthropologists like me are used to just excavate graves, 233 00:27:41,080 --> 00:27:45,760 from graveyards, but in this case, was completely different. 234 00:27:46,720 --> 00:27:50,000 It was the first time that I could study and excavate 235 00:27:50,480 --> 00:27:53,640 just the victims of a natural disaster. 236 00:27:54,760 --> 00:27:56,080 In that case, an eruption. 237 00:27:59,720 --> 00:28:02,120 Working on them, it's very, very important, 238 00:28:02,200 --> 00:28:05,920 it's very unique because within the town, 239 00:28:06,520 --> 00:28:09,360 we found just few victims. 240 00:28:09,800 --> 00:28:11,840 Some 20-30 victims. 241 00:28:22,080 --> 00:28:26,240 We thought that the large part of the inhabitants 242 00:28:26,320 --> 00:28:28,240 of Herculaneum just, they escaped. 243 00:28:31,680 --> 00:28:34,240 But that was an open question for decades. 244 00:28:35,920 --> 00:28:38,320 Why just very few people were there? 245 00:28:43,760 --> 00:28:47,520 In the '80s, the director of Herculaneum 246 00:28:47,600 --> 00:28:50,240 started an open-air excavation in the town. 247 00:28:51,760 --> 00:28:55,000 The excavators wanted to find victims. 248 00:28:55,760 --> 00:28:58,280 They were asking themselves, "Where are people?" 249 00:29:00,960 --> 00:29:05,840 They just start the excavation in the suburban area, 250 00:29:06,760 --> 00:29:10,680 and 1981, they reached the beach. 251 00:29:14,280 --> 00:29:18,120 They start to excavate on the beach area 252 00:29:18,440 --> 00:29:22,240 and suddenly, they found something extraordinary. 253 00:29:32,280 --> 00:29:34,080 During the excavation, 254 00:29:34,240 --> 00:29:39,720 they just start to see that there were several chambers. 255 00:29:41,840 --> 00:29:47,080 And later they saw that these boat chambers were just facing the sea. 256 00:29:48,920 --> 00:29:51,200 And the finding within the boat chambers 257 00:29:51,320 --> 00:29:55,680 was something very surprising and also exceptional. 258 00:29:58,720 --> 00:30:01,560 There inside, they found a lot of victims. 259 00:30:03,920 --> 00:30:08,600 In one room, you had maybe 40 skeletons. 260 00:30:10,560 --> 00:30:14,400 They start to excavate on the beach area, 261 00:30:16,240 --> 00:30:21,600 and then they found 30, 40 victims just laying on the beach. 262 00:30:23,880 --> 00:30:27,400 Altogether, the victims found within the boat chambers 263 00:30:27,480 --> 00:30:31,840 and on the beach are around 10 times more victims than in the town. 264 00:30:36,080 --> 00:30:38,840 So, we wanted to know, who were these people? 265 00:30:40,240 --> 00:30:41,720 And how did they die? 266 00:30:45,160 --> 00:30:50,480 The excavation and the study of the victims was a very complicated job. 267 00:30:53,040 --> 00:30:58,680 So imagine that you have altogether 8,000, 9,000, 10,000 bones. 268 00:31:04,120 --> 00:31:08,640 So the first part of the job was just to recognize 269 00:31:08,880 --> 00:31:13,200 a single individual and then to start to remove the ash. 270 00:31:15,080 --> 00:31:16,840 That job we did with water. 271 00:31:20,240 --> 00:31:23,160 And in that way, we could just see 272 00:31:23,400 --> 00:31:27,080 all the skeletons all together and make a documentation 273 00:31:27,160 --> 00:31:28,360 for each individual. 274 00:31:30,520 --> 00:31:34,080 In Herculaneum, in the first deposit, 275 00:31:34,400 --> 00:31:37,120 there are no big pumice like in Pompeii, 276 00:31:38,040 --> 00:31:39,720 so this is quite different 277 00:31:40,320 --> 00:31:42,440 in the two towns, in the two sites. 278 00:31:44,240 --> 00:31:45,760 The ash is very fine. 279 00:31:46,520 --> 00:31:51,320 So, it was very easy to excavate the victims. 280 00:31:56,680 --> 00:31:58,880 But we don't know who were these people. 281 00:32:02,600 --> 00:32:05,440 In this case, we found these two females, 282 00:32:05,920 --> 00:32:09,320 just close to each other, 283 00:32:09,400 --> 00:32:12,680 and between the legs of these two women, 284 00:32:12,760 --> 00:32:16,600 there were found two small children. 285 00:32:19,360 --> 00:32:20,840 And also what is interesting, 286 00:32:20,920 --> 00:32:24,720 that through the analysis of DNA of these people, 287 00:32:24,800 --> 00:32:27,800 we know that most of the women, 288 00:32:27,880 --> 00:32:29,880 they are just local. 289 00:32:30,600 --> 00:32:35,480 But many of males are coming from other localities, 290 00:32:35,760 --> 00:32:39,560 like, for instance, the Mediterranean area, 291 00:32:39,640 --> 00:32:42,080 Near East or Central Europe and so on. 292 00:32:45,240 --> 00:32:47,400 So we wanted to know why 293 00:32:47,480 --> 00:32:50,880 there is a mix of nationalities here in Herculaneum. 294 00:32:52,920 --> 00:32:54,280 There was an intriguing clue. 295 00:32:56,680 --> 00:33:02,720 This is chamber number 10 and here, this individual 296 00:33:03,000 --> 00:33:06,800 is a male, 35 years old, about. 297 00:33:07,920 --> 00:33:11,640 And we found a metal ring around the ankle. 298 00:33:14,160 --> 00:33:15,880 And he was not the only one. 299 00:33:18,320 --> 00:33:23,800 So it's sure they were slaves, and also we know that a lot of them, 300 00:33:23,880 --> 00:33:27,320 a lot of people came from other countries. 301 00:33:28,960 --> 00:33:32,080 So very probably they came at least as slaves. 302 00:33:36,360 --> 00:33:38,280 The big question is, how did they die? 303 00:33:41,320 --> 00:33:47,680 I saw hundreds of skeletons and victims, but never something like this. 304 00:33:57,840 --> 00:34:02,800 Archaeologists, from long time, they always said and thought 305 00:34:03,400 --> 00:34:07,400 that the people died all over 306 00:34:07,800 --> 00:34:10,800 and all around Vesuvius, Pompeii, Herculaneum, and so on, 307 00:34:12,440 --> 00:34:17,120 they died of suffocation because of the hot gases. 308 00:34:19,120 --> 00:34:22,400 In some cases, they were found on one side 309 00:34:22,480 --> 00:34:26,760 with hands on their faces to try to do the last breath. 310 00:34:29,280 --> 00:34:35,720 But I found, in the boat chambers, evidence that didn't fit with this theory. 311 00:34:39,840 --> 00:34:44,760 This is the skull of a victim found within a boat chamber, 312 00:34:45,280 --> 00:34:49,280 and we have some reddish-brown 313 00:34:50,240 --> 00:34:53,840 mineral residual within this skull, 314 00:34:54,480 --> 00:34:57,280 so the brain was very rapidly boiling, 315 00:34:58,680 --> 00:35:01,560 and that caused the skull to explode. 316 00:35:03,880 --> 00:35:07,040 So now we know that people in the boat chambers 317 00:35:07,120 --> 00:35:10,480 were not suffocated by ash and gas. 318 00:35:11,600 --> 00:35:14,640 The temperatures was high enough to kill them instantly. 319 00:35:22,680 --> 00:35:26,200 But bodies in Pompeii looks different to the ones in Herculaneum. 320 00:35:27,600 --> 00:35:32,200 So does it mean that the pyroclastic flow was different here? 321 00:35:34,680 --> 00:35:38,920 In Pompeii, many people show this 322 00:35:39,000 --> 00:35:43,800 kind of pugilistic attitude, so it seems that you are 323 00:35:43,880 --> 00:35:47,000 preparing yourself, just trying to defend yourself. 324 00:35:47,120 --> 00:35:48,160 But it's not true. 325 00:35:48,440 --> 00:35:50,600 It is something after you die. 326 00:35:52,360 --> 00:35:56,920 You see that the bodies were just kept complete, 327 00:35:57,720 --> 00:36:00,680 full of bones, flesh, everything. 328 00:36:03,640 --> 00:36:07,680 In Herculaneum, you don't have this kind of attitude, 329 00:36:08,240 --> 00:36:12,240 and that's due to the rapid disappearing of the flesh. 330 00:36:14,240 --> 00:36:17,080 All evidence shows that the temperature 331 00:36:17,160 --> 00:36:21,880 of the pyroclastic surge was much higher in Herculaneum than in Pompeii. 332 00:36:30,600 --> 00:36:34,520 When I saw the corpses of victims in Herculaneum, 333 00:36:35,680 --> 00:36:40,800 I thought that it was really a terrible situation at that time, 334 00:36:41,600 --> 00:36:45,960 to see all these people, young people, children and so on, 335 00:36:46,040 --> 00:36:50,320 all together, that was really something very unbelievable. 336 00:36:54,520 --> 00:36:55,880 Very probably they didn't know 337 00:36:55,960 --> 00:37:00,040 that Vesuvius was a volcano, but they knew very well earthquakes. 338 00:37:00,120 --> 00:37:04,920 That's why they were just within the boat chambers, 339 00:37:05,680 --> 00:37:08,280 because that was very safe from earthquakes, 340 00:37:08,360 --> 00:37:10,240 but not in case of an eruption. 341 00:37:17,400 --> 00:37:21,440 JERRAM: What is still puzzling to me is the difference between both towns. 342 00:37:22,520 --> 00:37:24,840 Why so few bodies in Herculaneum? 343 00:37:25,640 --> 00:37:27,600 And why so many in Pompeii? 344 00:37:29,600 --> 00:37:31,560 You can see that there's this huge wall 345 00:37:31,840 --> 00:37:34,520 of volcanic debris that came down off the volcano. 346 00:37:36,040 --> 00:37:39,640 Some 60-plus feet of debris lying above my head. 347 00:37:42,800 --> 00:37:44,560 But that just didn't happen in an instant. 348 00:37:46,680 --> 00:37:48,680 When you look a bit closer, and I can see here, 349 00:37:48,760 --> 00:37:51,320 you can actually see changes in the layers. 350 00:37:53,720 --> 00:37:57,320 What it shows is not just one pyroclastic flow, 351 00:37:57,400 --> 00:37:59,040 but a whole succession of them. 352 00:38:02,280 --> 00:38:07,440 And what we can do is we can walk up through this layer cake of rock 353 00:38:07,920 --> 00:38:13,200 and work out exactly how many of these pyroclastic flows came down 354 00:38:13,280 --> 00:38:15,800 during the eruption of Mount Vesuvius. 355 00:38:17,360 --> 00:38:18,960 The evidence here in this wall 356 00:38:19,040 --> 00:38:22,200 shows us that there was at least six different pyroclastic flows. 357 00:38:25,920 --> 00:38:28,080 And it's the first two that bury Herculaneum. 358 00:38:29,480 --> 00:38:31,560 But they don't entirely reach Pompeii. 359 00:38:33,920 --> 00:38:35,760 And that is a big clue as to what happened. 360 00:38:36,320 --> 00:38:38,080 It was one volcano and one eruption, 361 00:38:38,520 --> 00:38:41,560 but two different sequences of events in each city. 362 00:38:43,680 --> 00:38:46,520 So what determined whether you lived or died? 363 00:38:46,760 --> 00:38:49,160 And if you died, how you died? 364 00:38:56,480 --> 00:38:58,280 (RUMBLING) 365 00:39:05,440 --> 00:39:08,880 Now I can fully unravel the timeline of what happened 366 00:39:09,160 --> 00:39:12,000 in the AD 79 eruption of Mount Vesuvius. 367 00:39:29,840 --> 00:39:32,280 At around midday, the volcano erupted. 368 00:39:35,320 --> 00:39:39,200 It's explosive, and it's more powerful than anything you can imagine. 369 00:39:40,720 --> 00:39:44,200 Millions of tons of rock, pumice and ash are ejected, 370 00:39:45,200 --> 00:39:50,600 forming a giant column of ash and debris towering 20 miles into the sky. 371 00:39:51,920 --> 00:39:55,640 And it's by sheer bad luck that these stratospheric winds 372 00:39:56,040 --> 00:39:59,920 take the debris, carry the debris over and drop it onto Pompeii. 373 00:40:01,480 --> 00:40:07,120 Ash and pumice would continue to rain down for the next 18-20 hours, 374 00:40:07,280 --> 00:40:11,280 trapping people inside their homes, like the two people found together 375 00:40:11,360 --> 00:40:12,360 at the villa. 376 00:40:13,680 --> 00:40:16,600 The first buildings start to collapse under the weight of the debris. 377 00:40:21,040 --> 00:40:24,960 PETRONE: While people were just dying in Pompeii, we know, actually, 378 00:40:25,040 --> 00:40:28,680 that most of Herculaneum was just evacuated. 379 00:40:29,440 --> 00:40:32,120 They escaped in the north direction, through Naples. 380 00:40:34,160 --> 00:40:36,920 JERRAM: Sadly, some stayed behind in Herculaneum 381 00:40:37,000 --> 00:40:39,040 sheltered in the boat chambers. 382 00:40:43,120 --> 00:40:46,920 Some 12 hours after the eruption, the ash column collapses. 383 00:40:48,200 --> 00:40:51,840 The first pyroclastic flow travels at over 100 miles an hour 384 00:40:52,400 --> 00:40:54,120 in the direction of Herculaneum. 385 00:40:59,040 --> 00:41:03,560 So we know that the first pyroclastic surge came into the city, 386 00:41:04,560 --> 00:41:08,760 went into the buildings, killed the people here in the town, 387 00:41:10,000 --> 00:41:12,520 reached rapidly the beach, 388 00:41:13,080 --> 00:41:16,520 and the temperature is at least 500° centigrade. 389 00:41:28,320 --> 00:41:32,120 They died just in a fraction of a second. They had no time to react. 390 00:41:33,920 --> 00:41:35,680 So the people didn't feel anything. 391 00:41:40,520 --> 00:41:42,920 JERRAM: Over in Pompeii, things played out differently. 392 00:41:44,760 --> 00:41:46,800 It's spared the first pyroclastic flow. 393 00:41:48,400 --> 00:41:51,800 Instead, the city is pelted by a shower of pumice. 394 00:42:00,080 --> 00:42:02,880 After 18 hours, the pumice fall starts to ease. 395 00:42:05,800 --> 00:42:07,440 (TONIOLO SPEAKING) 396 00:42:23,080 --> 00:42:25,560 JERRAM: But it's a short-lived period of calm 397 00:42:25,640 --> 00:42:28,960 before Mount Vesuvius launches another pyroclastic flow. 398 00:42:33,040 --> 00:42:34,160 (TONIOLO SPEAKING) 399 00:42:36,880 --> 00:42:39,640 This pyroclastic flow does reach Pompeii. 400 00:42:41,480 --> 00:42:44,200 It traveled further than the ones that hit Herculaneum, 401 00:42:44,880 --> 00:42:47,760 so it was slightly cooler, but still lethal. 402 00:43:00,360 --> 00:43:03,680 TONIOLO: They didn't know what was happening, and they died. 403 00:43:05,720 --> 00:43:09,000 I worked in Pompeii for many years, 404 00:43:09,080 --> 00:43:12,920 but this was very unique because here you really have 405 00:43:13,000 --> 00:43:17,840 a very important and particular picture of 79 AD. 406 00:43:18,960 --> 00:43:21,560 And this clearly was terrible. 407 00:43:24,920 --> 00:43:27,680 It's the fourth and the fifth, and eventually the sixth 408 00:43:27,760 --> 00:43:31,600 that completely cover the area, and it is, I mean, 409 00:43:31,680 --> 00:43:35,440 even this preserved bit here is a harrowing scene. 410 00:43:37,280 --> 00:43:38,640 Absolute chaos.
