According to Scientific American:
Researchers say that references to planets and constellations in the Odyssey describe a solar eclipse that occurred in 1178 B.C., nearly three centuries before Homer is believed to have written the story. If correct, the finding would suggest that the ancient poet had a surprisingly detailed knowledge of astronomy.
Those familiar with The Odyssey should not be surprised at all by this claim. Just look at the names of the characters and lands which Odysseus encounters on his way home. From the first line of the epic poem (Hom. Od. 1.1) we learn that Odysseus finds himself in the lands of Helios Hyperion (the sun) and Calypso (the ‘Concealer’). These are just two of many people and places with “sun” or “darkness” related names in the epic.
