Sagaris is a river of Phrygia, formerly called Xerobates because in the summer time it was generally dry. But it was called Sagaris for this reason: Sagaris, the son of Myndon and Alexirrhoe, contemning and slighting the mysteries of the Mother of the Gods, frequently affronted and derided her priests the Galli. At which the Goddess heinously offended, struck him with madness to that degree, that in one of his raging fits he flung himself into the river Xerobates, which from that time forward was called Sagaris.

In this river grows a stone, which is called autoglyphus, that is, naturally engraved; for it is found with the Mother of the Gods by nature engraved upon it. This stone, which is rarely to be found, if any of the Galli or gelded priests happen to light upon, he makes no wonder at it, but undauntedly brooks the sight of a preternatural action;—as Aretazes reports in his Phrygian Relations.

Near to this river lies the mountain Ballenaeus, which in the Phrygian language signifies royal; so called from Ballenaeus, the son of Ganymede and Medesigiste, who perceiving his father almost wasted with a consumption, instituted the Ballenaean festival, observed among the natives to this day.

In this river is to be found a stone called aster, which from the latter end of autumn shines at midnight like fire. It is called in the language of the natives ballen, which being interpreted signifies a king;—as Hermesianax the Cyprian affirms in his Second Book of his Phrygian Relations.
