Simonides passed much of his life at the courts of princes, and often employed his talents in pangyric and festal odes, receiving his reward from the munificence of those whose exploits he celebrated. This employment was not derogatory, but closely resembles that of the earliest bards, such as Demodocus, described by Homer, or of Homer himself, as recorded by tradition.
On one occasion, when residing at the court of Scopas, the king of Thessaly, the prince desired him to prepare a poem in celebration of his exploits, to be recited at a banquet. In order to diversify his theme, Simonides, who was celebrated for his piety, introduced into his poems the exploits of Castor and Polydeuces. Such digressions were not unusual with the poets on similar occasions, and one might suppose an ordinary mortal might have been content to share the praises of the sons of Leda. But vanity is exacting; and as Scopas sat at his festal board among his courtiers and sycophants, he grudged every verse that did not rehearse his own praises. When Simonides approached to receive the promised reward Scopas bestowed but half the expected sum, saying, "Here is payment for my portion of thy performance; Castor and Polydeuces will doubtless compensate thee for so much as relates to them." The disconcerted poet returned to his seat amidst the laughter which followed the great man's jest. In a little time he received a message that two young men on horseback were waiting without and anxious to see him. Simonides hastened to the door, but looked in vain for the visitors. Scarcely, however, had he left the banqueting hall when the roof fell in with a loud crash, burying Scopas and all his guests beneath the ruins. On inquiring as to the appearance of the young men who had sent for him, Simonides was satisfied that they were no other than Castor and Polydeuces themselves.
