Crissa was more ancient than Cirrha, and was situated inland a little southwest of Delphi, at the southern end of a projecting spur of Mount Parnassus. Crissa gave name to the Crissaean Gulf, and its ruins may still be seen at a short distance from the modern village of Chrisso. Cirrha was built subsequently at the head of the gulf, and rose into a town from being the port of Crissa. This is in accordance with what we find in the history of other Grecian states. The original town is built upon a height at some distance from the sea, to secure it against hostile attacks, especially by sea; but in course of time, when property has become more secure, and the town itself has grown in power, a second place springs up on that part of the coast which had served previously as the port of the inland town. This was undoubtedly the origin of Cirrha, which was situated at the mouth of the river Pleistus, and at the foot of Mount Cirphis.
