a distinguished poet and grammarian, was the son of Polymnetus, and was born at Chalcis in Euboea, b.c. 274. He studied philosophy under Lacydes and Prytanis, and poetry under Archebulus the Therean. After amassing great wealth, he retired (b.c. 221) to the court of Syria, and there assisted Antiochus the Great in forming the royal library at Antioch, which it was intended should rival that of Alexandria; and in this employment Euphorion died. Only a few fragments of his works have been preserved; but from the opinions expressed by ancient writers, it appears that the erudite character of his allusions rendered him so obscure that he was difficult to be understood, and that he was constantly in search of archaic and obsolete expressions. As late as the times of the Emperor Tiberius, the works of Euphorion were still sufficiently popular. The fragments have been edited by Meineke under the title De Euphorionis Chalcedensis Vita et Scriptis, &c., Gedani, 1823. See also Clinton's Fasti Hellenici, vol. ii. p. 511; Fabricius, Bib. Graec., vol. i. p. 594; Heyne, De Euphoriione, et Excurs. iii. ad Virg. Eclog. vi. 64, and Excurs. v. ad Æn. ii.
