A Dictionary of Greek and Roman biography and mythology

(Ἀπελλᾶς), a sculptor, who made, in bronze, statues of worshipping females (ad orantes feminas, Plin. Nat. 34.19.26). He made the statue of Cynisca, who conquered in the chariotrace at Olympia. (Paus. 6.1.2.) Cynisca was sister to Agesilaus, king of Sparta, who died at the age of 84, in 362 B. C. Therefore the victory of Cynisca, and the time when Apellas flourished, may be placed about 400 B. C. His name indicates his Doric origin. (Tölken, Amalthea, iii. p. 128.)
