For, as the story goes, some of the Coans fishing with a net, some strangers, Milesians, bought the draught at a venture; the net brought up a golden tripod, which, they say, Helen, at her return from Troy, upon the remembrance of an old prophecy, threw in there. Now, the strangers at first contesting with the fishers about the tripod, and the cities espousing the quarrel so far as to engage themselves in a war, Apollo decided the controversy by commanding to present it to the wisest man; and first it was sent to Miletus to Thales, the Coans freely presenting him with that for which they fought against the whole body of the Milesians; but Thales declaring Bias the wiser person, it was sent to him; from him to another; and so, going round them all, it came to Thales a second time; and, at last, being carried from Miletus to Thebes, was there dedicated to Apollo Ismenius. Theophrastus writes that it was first presented to Bias at Priene; and next to Thales at Miletus, and so through all it returned to Bias, and was afterwards sent to Delphi.
Plutarch, Life of Solon. Thales and Bias were two of the traditional Seven Sages of Greece. Diogenes Laertius also tells the story in his life of Thales, giving several versions of the story.
