Marcelo Magnasco on the Eclipse in the Odyssey Back at the beginning of the century an astronomer named Carl Schoch decide to try to date a passage in the Odyssey that has been interpreted by many since classical times explaining the description of an eclipse. It’s a little bit of a difficult passage to try to interpret this lunar eclipse because the passage takes place indoors and the suitors who are supposed to be seeing this omen do not see it. But otherwise the description of an eclipse by Carl Schoch is very vivid. So Carl Schoch tried to date this eclipse and he found that the only possible date would have been April 16, 1178 BC, which could agree rather well with the classical estimates of the Fall of Troy around 1190 BC okay the last ten years it takes for Odysseus to get back. We took these and we said okay if this is the only evidence that you find then the Odyssey is just a social story right; you can it’s neither here nor there right, what are you going to do. You can’t corroborate it by any means just looking at the tapes. However, in the Odyssey there’s plenty of other references to things that happen in the sky. There’s a reference to Odysseus navigating by the stars, there’s a reference to seeing Venus high in the sky and so what we did was we set aside the eclipse reference and we just took the rest of the other references and looking at all those other references we found that because each one of them happens frequently but in combination all four of them would happen very rarely we were able to say that the only date compatible with these other references was also April 16, 1178 BC. So this gave us what we believe is a fully independent confirmation that on that date might be the date that’s actually inscribed in the Odyssey. Yes, so the eclipse being described would be a total solar eclipse lasting a few minutes as they typically do and the narrative takes place at noon so that’s an important data and eclipses are very short and they are seen over very sort of, total solar eclipses are very short and they are seen over a very small swath of the earth because the size of the moon and the size of the sun are the apparent size of the moon and the sun are so near identical that when the moon covers the sun you have to be exactly at one given position and it doesn’t last very long so the description would be compatible with a total solar eclipse. The description says that it happens at noon, indeed the 16, April, 1178 BC eclipse happened close to noon time local time over the Ionian Islands so yeah in addition that particular eclipse would have been pretty impressive because you had all of the planets, all of the visible naked eye planets all of them simultaneously in the sky in a relatively small fraction of the sky as the eclipse happened so it would have been a pretty impressive, pretty impressive phenomenon.
