Ampycus

Mopsus was the son of Ampycus.

Apollo and Ampycus were the same.

But in the next night the rest of the chieftains, overcome by sleep, were resting during the latest period of the night, while Acastus and Mopsus the son of Ampycus kept guard over their deep slumbers.

Thereupon on the same day a pitiless fate seized Mopsus too, son of Ampycus; and he escaped not a bitter doom by his prophesying; for there is no averting of death.

And straightway Argus drew Aeson's son apart from his comrades as soon as he heard from his brothers that Medea had gone at daybreak to the holy shrine of Hecate, and led him over the plain; and with them went Mopsus, son of Ampycus, skilled to utter oracles from the appearance of birds, and skilled to give good counsel to those who set out on a journey.
