How the ancients saw eclipses
From our UK edition
By the 5th century bc, probably thanks to the Babylonians, enlightened Greeks were well aware that eclipses were natural phenomena. On 3 August 431 bc, Pericles was about to lead his triremes into battle when a solar eclipse occurred, and panic broke out among his men at the ‘omen’. Pericles promptly wrapped a cloak around his helmsman’s eyes and asked whether he thought that was an omen. ‘Of course not,’ replied the helmsman. ‘Same difference,’ said Pericles. ‘The eclipse has just been caused by something bigger than this cloak.’ There was a very different outcome when a lunar eclipse occurred as the Athenian army was about to retreat from Sicily (27 August, 413 bc): the general Nicias ordered a fatal 3 x 9 day delay.
