The Ionian city of Priene had originally been situated along the mouth of the Maeander River but in about 350 BCE the citizens build a new city farther inland on the present site (near present Turunclar, Turkey), laying the streets on a grid plan at the foot of a spectacular cliff.

Phocis retains control of Delphi and continues the building of the temple, although other Greeks express their resentment at the lavish display of valuable ornaments on Phocian women at the Pythian games of 350 BCE.

Phayllus, after serving two years as war archon of Phocis, dies of illness and is succeeded by his nephew Phalaecus, Onomarchus' son, …
