Temple of Apollo Patroos
Next to the Stoa of Zeus at the south are the remains of a small temple of Apollo Patroos (Fatherly), so-called because he was the father of Ion, founder of the Ionian Greeks, a tribe that included the Athenians (Fig. 10). Dated to the second half of the 4th century B.C., the temple had Ionic columns only across the front (probably six, though four is possible). A monumental marble statue found in the ruins seems to be the cult statue by Euphranor mentioned by Pausanias (Fig. 11).
"Euphranor also made the Apollo called Patroos in the temple nearby. In front of the temple one Apollo was made by Leochares, the other -- whom they call Alexikakos (averter of evil) -- by Kalamis. They say the god received this name because by an oracle from Delphi he stopped the plague which was afflicting them at the same time as the Peloponnesian War." (Pausanias 1.3.4)
