Hudson-Williams' commentary to Theognis 702f.:
Sisyphus : the type of shrewdness and cunning ; he is often mentioned in connexion with Odysseus, who was sometimes regarded as his son (Soph. Philoctetes 417) ... Sisyphides = Ulixes Ov. Ars. Am. 3, 313. ' Ulixi Sisyphique prudentiam' Cic. Tusc. 1. 41 ... Sisyphus instructed his wife not to give his body burial. In the underworld he complained of her neglect, and persuaded Pluto to let him return and punish her. He then refused to leave the upper world, and Hermes was sent to fetch him down.
