4. An Athenian, a contemporary of the philosopher Marinus. He was distinguished for his liberality and his enormous wealth, which he employed in helping needy persons and restoring decayed towns. The philosophers and literary men of his day found in him a munificent, though rather imperious patron. (Suid. s. v. Θεαγ.; Damasc. apud Phot. p. 346a. ed. Bekker.)
