Plutarch, Pericles
Bernadotte Perrin, Ed.

Be that true or not, when Pericles learned of the disaster which had befallen his fleet, he came speedily to its aid. And though Melissus arrayed his forces against him, he conquered and routed the enemy and at once walled their city in, preferring to get the upper hand and capture it at the price of money and time, rather than of the wounds and deadly perils of his fellow-citizens. [2] And since it was a hard task for him to restrain the Athenians in their impatience of delay and eagerness to fight, he separated his whole force into eight divisions, had them draw lots, and allowed the division which got the white bean to feast and take their ease, while the others did the fighting. And this is the reason, as they say, why those who have had a gay and festive time call it a ‘white day,’—from the white bean. [3]

Ephorus says that Pericles actually employed siege-engines, in his admiration of their novelty, and that Artemon the engineer was with him there, who, since he was lame, and so had to be brought on a stretcher to the works which demanded his instant attention, was dubbed Periphoretus. Heracleides Ponticus, however, refutes this story out of the poems of Anacreon, in which Artemon Periphoretus is mentioned many generations before the Samian War and its events. [4] And he says that Artemon was very luxurious in his life, as well as weak and panic-stricken in the presence of his fears, and therefore for the most part sat still at home, while two servants held a bronze shield over his head to keep anything from falling down upon it. Whenever he was forced to go abroad, he had himself carried in a little hammock which was borne along just above the surface of the ground. On this account he was called Periphoretus.
