Proper name.
[sc. It was he] who married Arsinoe, the mother of Ptolemaios the Saviour.[1] This Ptolemaios, not related to him at all, Lagos in fact exposed upon a bronze shield. And a story is current out of Macedonia that says an eagle used to visit [him] and, stretching down its wings while raising itself, protected him both from the direct ray of the sun and, whenever it rained, from heavy rain.[2] It would terrify the ordinary birds, tear apart quails, and offer their blood to him as food, like milk.[3]
