Callias
2. A wealthy Athenian, who, on condition of marrying Cimon's sister, Elpinice, paid for him the fine of fifty talents which had been imposed on Miltiades. (Plut. Cim. 4; Nepos, Cim. 1.) He appears to have been unconnected with the nobler family of Callias and Hipponicus, the δᾳδοῦχοι. It seems likely that his wealth arose from mining, and that it was a son or grandson of his who discovered a method of preparing cinnabar, B. C. 405. (Böckh, Dissert. on the Mines of Laurion, § 23.)
