Yipes! What did they see?

Who said the classics are not relevant! The following passage from the life of Lysander, the Spartan general who defeated Athens in 406BC , contains an intriguing digression by Plutarch,

XII. "Some affirmed, that when Lysander's ship sailed out of the harbour of Lampsakus to attack the enemy, they saw the Dioskuri, like two stars, shining over the rudders[147]. Some also say that the fall of the great stone was an omen of this disaster: for the common belief is that a vast stone fell down from Heaven into the Goat's Rivers, which stone is even now to be seen, and is worshipped by the people of the Chersonese…. [Then Plutarch speculates about the origin of shooting stars for about ten lines. Then he relates a sighting, 500 years before his day, that has a familiar ring to it. Colored italics mine]….
This theory of Anaxagoras is confirmed by Daimachus in his treatise on Piety, where he states that for seventy-five days before the stone fell a fiery body of great size like a burning cloud, was observed in the heavens. It did not remain at rest, but moved in various directions by short jerks, so that by its violent swaying about many fiery particles were broken off, and flashed like shooting-stars. When, however, it sank to the earth, the inhabitants, after their first feeling of terror and astonishment were passed, collected together, and found no traces of fire, but merely a stone lying on the ground, which although a large one, bore no comparison to that fiery mass. It is evident that this tale of Daimachus can only find credit with indulgent readers: but if it be true, it signally confutes those who argue that the stone was wrenched by the force of a whirlwind from some high cliff, carried up high into the air, and then let fall whenever the violence of the tempest abated. Unless, indeed, that which was seen for so many days was really fire, which, when quenched, produced such a violent rushing and motion in the air as tore the stone from its place. A more exact enquiry into these matters, however, belongs to another subject."
