Athenaeus, Deipnosophistae 552b:
“The poet Philitas of Kos was of a slight figure, and on account of the leanness of his body, he wore balls made of lead on his feet, so that he would not be blown over by the wind.”
λεπτότερος δ᾽ ἦν καὶ Φιλίτας ὁ Κῷος ποιητής, ὃς καὶ διὰ τὴν τοῦ σώματος ἰσχνότητα σφαίρας ἐκ μολύβου πεποιημένας εἶχε περὶ τὼ πόδε ὡς μὴ ὑπὸἀνέμου ἀνατραπείη
