Chrysus of Cos, the fourteenth (or thirteenth) of the family of the Asclepiadae, was the youngest son of Nebrus, the brother of Gnosidicus, and the father of Elaphus; and lived in the sixth century B. C. in the island of Cos. During the Crissaean war, while the Amphyctions were besieging the town of Crissa in Phocis, the plague broke out among their army. Having consulted the oracle of Delphi in consequence, they were directed to fetch from Cos " the young of a stag, together with gold," which was interpreted to mean Nebrus and Chrysus. They accordingly persuaded them both to join the camp, where Chrysus was the first person to mount the wall at the time of the general assault, but was at the same time mortally wounded, 591 BC. He was buried in the hippodrome at Delphi, and worshipped by the inhabitants as a hero (enagizo). (Thessali Oratio, in Hippocr. Opera, vol. iii. p. 836;, &c.)
