Histories

When they had received the oracle, the Delphians first sent word of it to those Greeks who desired to be free; because of their dread of the barbarian, they were forever grateful. Subsequently they erected an altar to the winds at Thyia, the present location of the precinct of Thyia the daughter of Cephisus, and they offered sacrifices to them. This, then, is the reason why the Delphians to this day offer the winds sacrifice of propitiation.
