0:00:03.688,0:00:04.767 Good evening! 0:00:04.767,0:00:05.695 We are in one of the most important 0:00:05.695,0:00:10.530 archaeological sites of the world: 0:00:10.530,0:00:11.593 Pompeii. 0:00:11.593,0:00:12.508 We're in one of 0:00:12.508,0:00:15.853 the most important sites of Pompeii: 0:00:15.853,0:00:16.879 the big theater. 0:00:17.459,0:00:18.607 2000 years ago, you had 0:00:18.607,0:00:20.705 a thousand people watching 0:00:20.705,0:00:22.334 anyone on the stage. 0:00:22.334,0:00:25.014 But do we really know Pompeii? 0:00:26.006,0:00:26.976 Well, yes. 0:00:26.976,0:00:29.053 We've seen so many movies, 0:00:29.053,0:00:31.016 read so many novels 0:00:31.016,0:00:33.213 telling us about the big volcano, 0:00:33.213,0:00:35.916 telling us about the lava, 0:00:35.936,0:00:37.577 the lava flows and everything. 0:00:37.577,0:00:40.688 Well, in fact, there are many myths 0:00:40.688,0:00:41.987 to be cleared up. 0:00:42.637,0:00:43.535 First of all, 0:00:43.535,0:00:47.514 we didn't have any volcano visible at all. 0:00:47.514,0:00:49.314 And that is something that 0:00:49.324,0:00:52.527 can be shocking, but if you speak to 0:00:52.537,0:00:54.359 and have a lunch 0:00:54.359,0:00:57.337 maybe with a vulcanologist, 0:00:57.337,0:00:59.056 or an anthropologist, 0:00:59.056,0:01:00.496 or an archaeologist, 0:01:00.496,0:01:01.723 he will tell you 0:01:01.723,0:01:04.674 so many truths about Pompeii 0:01:04.674,0:01:06.955 that you will really be surprised to know. 0:01:06.955,0:01:07.735 First of all, 0:01:07.735,0:01:09.534 so we're talking about volcanoes. 0:01:09.534,0:01:12.011 Today it's a towering volcano. 0:01:12.011,0:01:13.793 But at the time of Pompeii, 0:01:13.793,0:01:14.802 it didn't exist, 0:01:14.802,0:01:17.270 for the simple reason that it started 0:01:17.270,0:01:20.454 to exist that day of the eruption. 0:01:20.454,0:01:22.507 From that day, it started to grow 0:01:22.507,0:01:24.577 and become what we see today. 0:01:24.577,0:01:26.832 So, what could the Pompeiians see? 0:01:26.832,0:01:27.682 Very simple. 0:01:27.692,0:01:31.166 There was a small mound with a crest. 0:01:31.166,0:01:33.590 And you can still see it today. 0:01:33.590,0:01:35.548 It's exactly where the big volcano 0:01:35.548,0:01:37.217 is sitting today. 0:01:37.217,0:01:40.727 And, if you could see it at that time, 0:01:40.727,0:01:42.692 you could have seen so many woods 0:01:42.692,0:01:46.958 You could have seen, I don't know, deer 0:01:46.958,0:01:48.772 Pompeiians would probably go there 0:01:48.772,0:01:51.305 to collect wood, pick up mushrooms, 0:01:51.305,0:01:52.259 make love. 0:01:52.259,0:01:54.538 It was a friend that betrayed them. 0:01:54.538,0:01:56.981 So, that's the first thing: no volcano, 0:01:56.991,0:01:58.654 the first myth to clear up. 0:01:58.654,0:02:00.938 And then, another thing is the lava. 0:02:00.948,0:02:02.771 You didn't have a single drop of lava 0:02:02.771,0:02:05.161 getting to Pompeii. Not a single one. 0:02:05.161,0:02:09.977 But, gases, ashes, lapilli, and so on. 0:02:09.977,0:02:11.267 So, that's another myth. 0:02:11.267,0:02:13.273 And we will see what happened exactly. 0:02:13.273,0:02:14.469 The third myth is about 0:02:14.469,0:02:17.712 the date of the eruption. 0:02:17.712,0:02:19.440 We know that everything happened 0:02:19.440,0:02:21.047 the 24th twenty-fourth of August, 0:02:21.047,0:02:22.630 in 79 A.D. 0:02:22.630,0:02:24.142 But how do we know that? 0:02:24.142,0:02:25.880 But, we know that because 0:02:25.880,0:02:29.261 Pliny the Younger wrote that in a letter. 0:02:29.261,0:02:30.212 He was a witness. 0:02:30.212,0:02:32.896 Actually, if you try to see, 0:02:32.896,0:02:35.343 there are at least seven witnesses, 0:02:35.343,0:02:39.116 seven survivors of the eruption. 0:02:39.116,0:02:41.099 Today, I would also like 0:02:41.099,0:02:42.256 to spend some time 0:02:42.256,0:02:44.164 to answer one question, that is: 0:02:44.164,0:02:46.845 "Would we have survived the eruption, 0:02:46.845,0:02:49.161 had we been there 0:02:49.161,0:02:50.563 almost 2000 years ago?" 0:02:50.563,0:02:51.960 So, Pliny the Younger said 0:02:51.960,0:02:53.172 that everything happened 0:02:53.172,0:02:55.921 on the 24th of August. 0:02:55.921,0:02:57.584 But how do we know that? 0:02:57.584,0:03:00.037 I told you there was a letter. 0:03:00.047,0:03:02.847 This letter, though, is not here anymore. 0:03:02.847,0:03:04.224 It vanished in time. 0:03:04.224,0:03:07.528 But, in the Middle Ages, the monks started 0:03:07.528,0:03:09.926 to write some copies of that letter. 0:03:09.926,0:03:12.018 And so we have three families 0:03:12.018,0:03:14.271 of that old letter made by monks 0:03:14.271,0:03:16.077 who were writing copies 0:03:16.077,0:03:18.193 and another one would copy the copy 0:03:18.193,0:03:19.045 and so forth. 0:03:19.045,0:03:21.161 But, of course, they would make mistakes. 0:03:21.161,0:03:23.803 So, is the date right or not? 0:03:23.803,0:03:25.741 Well, if you see the different letters, 0:03:25.741,0:03:27.906 you will see that they are different dates 0:03:27.906,0:03:31.526 One says "Nine days before 0:03:31.526,0:03:33.659 the Calends of September," 0:03:33.659,0:03:35.463 which is the 24th of August. 0:03:35.463,0:03:38.072 Another one says, "Nine days before 0:03:38.072,0:03:39.921 the Calends of November," 0:03:39.921,0:03:42.050 which is the 24th of October. 0:03:42.050,0:03:43.421 Where is the answer? 0:03:43.421,0:03:45.743 Well, the answer is buried here, 0:03:45.743,0:03:47.216 in the strata of Pompeii. 0:03:47.216,0:03:50.095 In fact, archaeologists have been finding 0:03:50.095,0:03:53.065 nuts, have been finding chestnuts, 0:03:53.075,0:03:55.926 dates, dried figs, 0:03:55.926,0:03:59.946 which are not really summer fruits, 0:03:59.946,0:04:02.953 but rather you find them in the fall. 0:04:02.953,0:04:04.751 And they've been finding 0:04:04.751,0:04:07.024 so many little clues 0:04:07.024,0:04:09.401 about the warm weather. 0:04:09.401,0:04:11.359 For instance, people were dressed up 0:04:11.359,0:04:13.827 with very warm clothes, 0:04:13.827,0:04:15.490 with scarves, for instance. 0:04:15.490,0:04:17.514 So, that means that, probably, 0:04:17.514,0:04:19.997 it was a very cold climate, 0:04:19.997,0:04:21.964 which makes more sense 0:04:21.964,0:04:23.612 if it is around November. 0:04:23.612,0:04:25.933 The one interesting clue, though, 0:04:25.933,0:04:27.435 is about wine. 0:04:27.435,0:04:29.454 In the diggings, 0:04:29.454,0:04:32.162 in the decades in the past, 0:04:32.162,0:04:36.135 archaeologists found some big jars 0:04:36.135,0:04:37.824 containing wine. 0:04:37.824,0:04:40.549 So, what the Romans would do 0:04:40.549,0:04:43.189 is that they would have grape harvests, 0:04:43.189,0:04:45.421 and they would collect grape juice, 0:04:45.421,0:04:48.776 put that in those big, gigantic jars 0:04:48.776,0:04:50.018 called dolia. 0:04:50.018,0:04:51.853 And they would wait ten days 0:04:51.853,0:04:53.494 for it to boil, to ferment, 0:04:53.494,0:04:54.822 and then, twenty days 0:04:54.822,0:04:56.681 just to check that everything was okay. 0:04:56.681,0:04:57.895 And then they would cover 0:04:57.895,0:04:58.984 and seal everything. 0:04:58.984,0:04:59.985 And that's exactly 0:04:59.985,0:05:01.913 what the archaeologists found. 0:05:01.913,0:05:03.231 So, as a matter of fact, 0:05:03.231,0:05:05.933 grape harvest was over 0:05:05.933,0:05:07.692 at least from a month. 0:05:07.692,0:05:10.516 And that would probably tell you 0:05:10.516,0:05:12.192 that the date of the eruption 0:05:12.192,0:05:15.997 was around the end of October. 0:05:15.997,0:05:19.206 So, 24th of October makes sense. 0:05:19.206,0:05:22.413 So, that, of course, is no definite proof, 0:05:22.413,0:05:24.071 but that's interesting to see that 0:05:24.071,0:05:26.642 such a known site like Pompeii 0:05:26.642,0:05:28.631 really is still an open site 0:05:28.631,0:05:30.983 with many discoveries to be done. 0:05:30.983,0:05:32.931 Another myth to be cleared up is that 0:05:32.931,0:05:35.244 Pompeii, we always see that in the movies, 0:05:35.244,0:05:39.568 was a city with wealthy people, 0:05:39.568,0:05:42.194 with banquets, gladiators, and so on. 0:05:42.194,0:05:43.921 Well, that's not the truth. 0:05:43.921,0:05:45.464 In the day of the eruption, 0:05:45.464,0:05:48.318 it was a city full in crisis. 0:05:48.318,0:05:50.968 There was no running water, 0:05:50.968,0:05:51.954 no running water, 0:05:51.954,0:05:54.050 So, no bathhouses, the thermae. 0:05:54.050,0:05:56.528 You didn't see anyone having fun 0:05:56.528,0:05:57.770 in the thermae, because 0:05:57.770,0:05:59.256 you didn't have water. 0:05:59.256,0:06:01.243 There was one therma working 0:06:01.243,0:06:05.020 which had its own reservoir of water. 0:06:05.020,0:06:06.661 So, maybe people would go there. 0:06:06.661,0:06:08.323 But, there was a big crisis. 0:06:08.323,0:06:10.661 And another thing is that, well, 0:06:10.661,0:06:12.148 you didn't have a lot of people 0:06:12.148,0:06:13.693 like in the old times in Pompeii 0:06:13.693,0:06:17.142 because you had a lot of earthquakes. 0:06:17.142,0:06:18.780 Earthquakes were a signal 0:06:18.780,0:06:23.188 of the eruption coming, getting close 0:06:23.188,0:06:25.224 like the magma was pushing 0:06:25.224,0:06:30.276 and provoking those earthquakes. 0:06:30.276,0:06:32.553 So, many people, especially aristocracy, 0:06:32.553,0:06:33.339 had gone away. 0:06:33.339,0:06:35.960 You had new people, new rich, 0:06:35.960,0:06:38.827 former slaves, the liberti, so called, 0:06:38.827,0:06:41.248 who would buy fancy houses 0:06:41.248,0:06:42.784 and they would live there. 0:06:42.784,0:06:44.929 But, you didn't have 0:06:44.929,0:06:47.004 the old society of Pompeii. 0:06:47.014,0:06:49.039 You didn't have running water. 0:06:49.039,0:06:50.752 Running water was not there, 0:06:50.762,0:06:52.724 because probably the aqueduct 0:06:52.724,0:06:54.271 was broken in some places, 0:06:54.271,0:06:55.544 maybe due to earthquakes, 0:06:55.574,0:06:58.982 maybe due to the swelling of the soil, 0:06:58.982,0:06:59.717 of the earth. 0:06:59.717,0:07:01.263 We don't know exactly. 0:07:01.263,0:07:02.656 So, as you can see, there are 0:07:02.656,0:07:04.181 many myths to be cleared up. 0:07:04.181,0:07:07.181 So, let's go to the day of the eruption. 0:07:07.181,0:07:08.713 What happened exactly? 0:07:08.713,0:07:10.578 And let's try to answer the question, 0:07:10.578,0:07:12.353 "Would I have survived?" 0:07:12.353,0:07:16.134 Well, first of all, let's go to that day. 0:07:16.134,0:07:18.181 If it was the 24th of October, 0:07:18.181,0:07:20.632 it was a Friday. Clear sky. 0:07:20.632,0:07:21.826 We know that because 0:07:21.826,0:07:22.830 one of the witnesses, 0:07:22.830,0:07:24.777 who was living 30 kilometers 0:07:24.777,0:07:27.268 away from here, saw everything. 0:07:27.268,0:07:29.481 So, imagine that it was probably, 0:07:29.481,0:07:30.495 we don't know, of course, 0:07:30.495,0:07:31.915 the end of October, 0:07:31.915,0:07:33.725 clear sky, maybe, 0:07:33.725,0:07:37.000 you know, a very cold morning, 0:07:37.000,0:07:38.166 and then, what happened? 0:07:38.166,0:07:39.818 Well, we know from the letter 0:07:39.818,0:07:41.329 of Pliny the Younger 0:07:41.329,0:07:43.060 that everything started, 0:07:43.060,0:07:45.379 more or less, at noon, lunchtime. 0:07:45.379,0:07:49.242 Well, vulcanologists found some clues 0:07:49.242,0:07:51.565 that everything happened slightly before. 0:07:51.565,0:07:52.921 Well, Pliny didn't see that; 0:07:52.921,0:07:54.181 he was 30 kilometers away. 0:07:54.181,0:07:56.491 But, probably, the volcano started 0:07:56.491,0:07:59.248 to open, crack open in that morning. 0:07:59.248,0:08:02.321 Because, you see, that small, 0:08:02.321,0:08:04.779 well, long mound, 0:08:04.779,0:08:08.192 similar to the back of a whale, 0:08:08.192,0:08:10.471 that betrayed the Romans, 0:08:10.471,0:08:11.901 was not a mound. 0:08:11.901,0:08:14.943 It was a volcano, a very old volcano, 0:08:14.943,0:08:17.305 silent volcano, that had not erupted 0:08:17.305,0:08:19.993 for the last centuries. 0:08:19.993,0:08:22.713 So, no one knew it was a volcano. 0:08:22.713,0:08:25.534 But that morning, it woke up. 0:08:25.534,0:08:27.738 And it started to crack open 0:08:27.738,0:08:29.954 and exactly, let's say, 0:08:29.954,0:08:31.839 the first hours of the morning 0:08:31.839,0:08:33.037 were terrible. 0:08:33.037,0:08:35.658 People, let's say, started to gather 0:08:35.658,0:08:38.232 in the Forum, which is, you know, 0:08:38.232,0:08:40.154 it was the central place, 0:08:40.154,0:08:42.439 central square of Pompeii. 0:08:42.439,0:08:43.723 Everyone would gather there 0:08:43.723,0:08:44.876 in the morning, usually, 0:08:44.876,0:08:46.056 just to get information, 0:08:46.056,0:08:47.000 to meet friends. 0:08:47.000,0:08:49.750 It was just like a tv set of that time. 0:08:49.750,0:08:51.047 And they started to gather. 0:08:51.047,0:08:52.713 And they saw something weird. 0:08:52.713,0:08:57.111 That very low mound was covered 0:08:57.111,0:08:59.876 with a kind of fog, let's say, 0:08:59.876,0:09:01.941 with ashes that had covered 0:09:01.941,0:09:03.474 one of the sides. 0:09:03.474,0:09:05.421 It looked like it had snowed. 0:09:05.421,0:09:08.281 And they started to speak, 0:09:08.281,0:09:09.322 one with the other, 0:09:09.322,0:09:10.090 "What happened?" 0:09:10.090,0:09:12.195 Well, some people probably came 0:09:12.195,0:09:13.193 from the countryside, 0:09:13.193,0:09:14.865 telling strange things, 0:09:14.865,0:09:16.817 telling people, "Well, you know, there, 0:09:16.817,0:09:20.022 we hear noises like thunder. 0:09:20.022,0:09:22.228 There is a strange smell of sulfur 0:09:22.228,0:09:23.772 just from that mountain." 0:09:23.772,0:09:26.421 But, then something happened. 0:09:26.421,0:09:29.725 The whole thing started to explode. 0:09:29.725,0:09:31.996 The mouth got opened and you had 0:09:31.996,0:09:35.714 a gigantic column of ashes, vapors, 0:09:35.714,0:09:36.901 going up in the sky. 0:09:36.901,0:09:38.085 It would reach more than 0:09:38.085,0:09:39.830 32 kilometers of height 0:09:39.830,0:09:42.047 in the hour, which is three times 0:09:42.047,0:09:46.371 what, actually, a jetliner can reach. 0:09:46.371,0:09:48.960 So, just imagine people seeing 0:09:48.960,0:09:51.015 that column going high in the sky, 0:09:51.015,0:09:53.216 just staring at something. 0:09:53.216,0:09:55.367 They didn't even know what a volcano was. 0:09:55.367,0:09:59.117 Well, this is just the beginning 0:09:59.117,0:10:00.421 of the tragedy. 0:10:00.421,0:10:02.081 If you think about that column 0:10:02.081,0:10:05.323 going up and expanding in the air, 0:10:05.323,0:10:07.195 that's what Pliny the Younger tells us, 0:10:07.195,0:10:11.099 you can imagine like a big stain of ink 0:10:11.099,0:10:13.176 getting bigger and bigger, 0:10:13.176,0:10:14.856 covering the sun. 0:10:14.856,0:10:16.278 And then, people started 0:10:16.278,0:10:17.194 to hear something. 0:10:17.194,0:10:20.472 It was just a noise of grail, 0:10:20.472,0:10:22.453 a noise of something falling. 0:10:22.453,0:10:24.663 Actually, you had the lapilli. 0:10:24.663,0:10:26.459 You can see them all around us. 0:10:26.459,0:10:28.605 Lapilli?

But after two or three hours, 0:12:34.349,0:12:37.574 it was that straight up lapilli, 0:12:37.574,0:12:38.558 more or less. 0:12:38.558,0:12:41.061 After that time, you couldn't 0:12:41.061,0:12:42.901 see anything outside Pompeii. 0:12:42.901,0:12:44.254 You couldn't see the roads, 0:12:44.254,0:12:46.315 just like when you have a heavy snow. 0:12:46.315,0:12:47.570 You couldn't see anything. 0:12:47.570,0:12:48.976 So, where could you go? 0:12:48.976,0:12:50.663 And another thing is that you had 0:12:50.663,0:12:52.021 like a fog coming down. 0:12:52.021,0:12:53.545 It was actually like a, 0:12:53.545,0:12:55.594 imagine a desert storm. 0:12:55.594,0:12:58.260 You had like ashes coming down. 0:12:58.260,0:12:59.472 You couldn't see 0:12:59.472,0:13:01.214 more than one or two meters. 0:13:01.214,0:13:03.610 And these ashes were containing 0:13:03.610,0:13:05.253 pieces of glass, actually, 0:13:05.253,0:13:06.534 that were actually 0:13:06.534,0:13:08.941 hurting your windpipe. 0:13:08.941,0:13:10.636 So you had to breathe with a cloth 0:13:10.636,0:13:12.516 dipped in water. 0:13:12.516,0:13:14.391 It was really a nightmare. 0:13:14.391,0:13:15.559 So it is normal to think 0:13:15.559,0:13:17.955 that people just hid in their houses. 0:13:17.955,0:13:19.975 What happened then? 0:13:19.975,0:13:22.206 Well, the lapilli started to accumulate. 0:13:22.206,0:13:25.367 Once they reached something like a meter, 0:13:25.367,0:13:27.858 a cubic meter, there would be 0:13:27.858,0:13:31.374 an equivalent of six men as weight. 0:13:31.374,0:13:33.346 So you had the roof starting to collapse. 0:13:33.346,0:13:35.794 Actually, one-third of the people 0:13:35.794,0:13:37.394 found dead in Pompeii 0:13:37.394,0:13:41.037 died due to the collapsing of the roofs 0:13:41.037,0:13:41.906 or the floors. 0:13:41.906,0:13:43.933 Probably you had also earthquakes 0:13:43.933,0:13:45.096 in that process. 0:13:45.096,0:13:48.045 So people were in the houses, screaming 0:13:48.045,0:13:49.206 asking for help. 0:13:49.206,0:13:50.620 No one could see anything. 0:13:50.620,0:13:52.718 It was like the end of the world for them. 0:13:52.718,0:13:55.368 And that, for twelve hours. 0:13:55.368,0:13:57.175 Twelve hours later 0:13:57.175,0:13:59.162 say, at one o'clock in the morning, 0:13:59.162,0:14:02.209 let's move and go to Ercolano. 0:14:02.209,0:14:03.641 Ercolano is another town, 0:14:03.641,0:14:05.772 very close to the sea, 0:14:05.772,0:14:07.407 between the sea and the volcano, 0:14:07.407,0:14:08.880 which is about six kilometers 0:14:08.880,0:14:09.976 away from the volcano; 0:14:09.976,0:14:12.489 Pompeii is about eight kilometers away. 0:14:12.489,0:14:14.452 So when archaeologists started to dig 0:14:14.452,0:14:17.661 through the strata in Ercolano, 0:14:17.661,0:14:19.986 they couldn't find dead people. 0:14:19.986,0:14:21.757 All you see are scattered skeletons. 0:14:21.757,0:14:23.192 So everyone thought that 0:14:23.192,0:14:27.556 the inhabitants of Ercolano had escaped, 0:14:27.556,0:14:28.673 escaped somewhere. 0:14:28.673,0:14:30.795 They had actually managed to survive. 0:14:30.795,0:14:32.842 But once the archaeologists 0:14:32.842,0:14:34.249 reached the beach 0:14:34.249,0:14:37.152 and got to the arches, the arcade 0:14:37.152,0:14:39.181 where, usually, the fishing boats 0:14:39.181,0:14:41.426 were parked, just like [in] a garage, 0:14:41.426,0:14:43.733 they found three hundred skeletons. 0:14:43.733,0:14:45.681 They all died in a single moment. 0:14:45.681,0:14:47.661 When you see those skeletons, 0:14:47.661,0:14:49.800 you realize something: they all died 0:14:49.800,0:14:52.669 without defending themselves. 0:14:52.669,0:14:53.963 It's just as if something 0:14:53.963,0:14:56.748 had unplugged life from their bodies. 0:14:56.748,0:14:58.079 Just, boom! 0:14:58.079,0:14:59.831 And what happened, 0:14:59.831,0:15:02.181 and the vulcanologists will tell you that, 0:15:02.181,0:15:05.051 is that the gigantic column 0:15:05.051,0:15:06.804 going up in the sky, 0:15:06.804,0:15:09.537 at a certain time, couldn't stand, 0:15:09.537,0:15:11.789 and it sat on itself, 0:15:11.789,0:15:13.181 it just went down 0:15:13.181,0:15:15.483 and transformed itself 0:15:15.483,0:15:17.350 into deadly avalanches 0:15:17.350,0:15:20.145 made of gas and ashes, 0:15:20.145,0:15:22.901 coming down at a speed of 0:15:22.901,0:15:24.716 one hundred kilometers per hour, 0:15:24.716,0:15:28.065 with a, let's say, a heat of between 0:15:28.065,0:15:30.551 five and six hundred degrees Celsius. 0:15:30.551,0:15:33.280 So, that killed the people instantly. 0:15:33.280,0:15:35.342 If you want to think what happened, 0:15:35.342,0:15:38.571 just imagine being on the shore 0:15:38.571,0:15:40.176 and watching in the night 0:15:40.176,0:15:42.161 the volcano, the red part, 0:15:42.161,0:15:45.161 let's say, of the eruption, 0:15:45.161,0:15:47.494 was instantly being covered by 0:15:47.494,0:15:49.278 that avalanche that's coming down. 0:15:49.278,0:15:50.722 You couldn't see anything. 0:15:50.722,0:15:53.421 But, you know, vulcanologists 0:15:53.421,0:15:55.110 would tell you, maybe you could see 0:15:55.110,0:15:58.401 some flare, something like 0:15:58.401,0:16:02.681 a flock of red, hot bats 0:16:02.681,0:16:03.895 coming toward you. 0:16:03.895,0:16:07.025 And people were instantly killed. 0:16:07.025,0:16:08.602 The fact that you have the bone 0:16:08.602,0:16:11.193 in contact with the ash layers 0:16:11.193,0:16:15.883 means that skin, organs, muscles 0:16:15.883,0:16:19.401 got vaporized in a matter of a second, 0:16:19.401,0:16:20.339 a few seconds. 0:16:20.339,0:16:22.324 So people died violently. 0:16:22.324,0:16:24.000 Let's go back to Pompeii. 0:16:24.000,0:16:25.225 It's morning. 0:16:25.225,0:16:27.656 People hear that things are changing. 0:16:27.656,0:16:28.750 Probably you don't have 0:16:28.750,0:16:30.949 the rain of lapilli anymore. 0:16:30.949,0:16:32.901 So they wouldn't go away. 0:16:32.901,0:16:35.062 But you have so many lapillis, 0:16:35.062,0:16:36.769 it's impossible to open the door. 0:16:36.769,0:16:38.325 So, actually, people go outside 0:16:38.325,0:16:39.087 from the roofs 0:16:39.087,0:16:41.320 and they start to run away. 0:16:41.320,0:16:42.783 But at that time, 0:16:42.783,0:16:45.553 the volcano does the same thing again, 0:16:45.553,0:16:48.569 sits on himself and transforms his column 0:16:48.569,0:16:51.019 on those deadly avalanches of gas. 0:16:51.019,0:16:52.201 The first one stopped 0:16:52.201,0:16:55.014 right at the suburbia of Pompeii. 0:16:55.014,0:16:56.068 The second one kills 0:16:56.068,0:16:57.116 anyone on the street. 0:16:57.116,0:16:58.743 And that's what you see 0:16:58.743,0:17:00.104 are those people, you see 0:17:00.104,0:17:02.512 in those glass frameworks. 0:17:02.512,0:17:03.814 These are the people 0:17:03.814,0:17:04.905 killed in that moment. 0:17:04.905,0:17:07.385 And the third one would come again 0:17:07.385,0:17:09.214 and break down walls, 0:17:09.214,0:17:12.316 open the roof and kill people inside. 0:17:12.316,0:17:13.793 And then there is another one, 0:17:13.793,0:17:16.229 the last one, that is so powerful, 0:17:16.229,0:17:17.592 it goes all the way, 0:17:17.592,0:17:20.205 even at thirty kilometers away 0:17:20.205,0:17:22.070 and Pliny the Younger, 0:17:22.070,0:17:24.020 the one that wrote that letter, 0:17:24.020,0:17:26.847 was almost afraid to die. 0:17:26.847,0:17:29.540 He was staying at thirty kilometers away. 0:17:29.540,0:17:31.331 So this is what happened 0:17:31.331,0:17:32.500 exactly in Pompeii. 0:17:32.500,0:17:35.238 So what you see today 0:17:35.238,0:17:37.809 is a place that probably 0:17:37.809,0:17:38.991 don't tell you much 0:17:38.991,0:17:42.777 about these problems, this atmosphere 0:17:42.777,0:17:43.695 that happened. 0:17:43.695,0:17:45.259 But when you find yourself 0:17:45.259,0:17:47.534 in front of one of those bodies 0:17:47.534,0:17:49.725 inside the glass frame, 0:17:49.725,0:17:51.357 just remember that 0:17:51.357,0:17:52.349 these are not statues. 0:17:52.349,0:17:54.841 These are not petrified people. 0:17:54.841,0:17:58.370 These are people in the process of dying 0:17:58.370,0:18:00.518 in that intimate moment of their life. 0:18:00.518,0:18:01.849 And we, I guess, 0:18:01.849,0:18:03.849 should pay respect to them every time. 0:18:03.849,0:18:04.898 Thank you. 0:18:04.898,0:18:09.797 (applause)
