(Γίλλος), a Tarentine, ransomed the Persian nobles, who had been sent by Dareius Hystaspis on an exploring expedition with DEMOCEDES, and who, on their return from Crotona, had been cast on the Iapygian coast, and reduced to slavery. Dareius offered Gillus any recompence he pleased, whereupon he requested the king's interposition to restore him to his native city, from which he had been banished; and he begged at the same time that this might be effected quietly through the mediation of the Cnidians, between whom and the Tarentines there was friendship, arising probably from their common origin. The attempt to procure his recal was made without success. (Hdt. 3.138; Müller, Dor. 1.6.12.)
