Near the latter is a temple of Dionysus of the Black Goatskin. In his honor every year they hold a competition in music, and they offer prizes for swimming-races and boat-races. There is also a sanctuary of Artemis surnamed Iphigenia, and a bronze Poseidon with one foot upon a dolphin. Passing by this into the sanctuary of Hestia, we see no image, but only an altar, and they sacrifice to Hestia upon it.
Of Apollo there are three temples and three images. One has no surname; the second they call Pythaeus, and the third Horius (of the Borders). The name Pythaeus they have learned from the Argives, for Telesilla[*](See Paus. 2.20.8.) tells us that they were the first Greeks to whose country came Pythaeus, who was a son of Apollo. I cannot say for certain why they call the third Horius, but I conjecture that they won a victory, either in war or by arbitration, in a dispute concerning the borders (horoi) of their land, and for this reason paid honors to Apollo Horius.
