Asbolus
A centaur, whom Hesiod ( Shield Of Heracles) calls a diviner, probably from his skill in observing or prophesying from the flight of birds. He fought against the Lapithae at the nuptials of Peirithous, and was subsequently nailed to a cross by Heracles, who is said to have made an epigram upon him, which is preserved in Philostratus.
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom The Shield Of Heracles
(ll. 178-190) And there was the strife of the Lapith spearmen gathered round the prince Caeneus and Dryas and Peirithous, with Hopleus, Exadius, Phalereus, and Prolochus, Mopsus the son of Ampyce of Titaresia, a scion of Ares, and Theseus, the son of Aegeus, like unto the deathless gods. These were of silver, and had armour of gold upon their bodies. And the Centaurs were gathered against them on the other side with Petraeus and Asbolus the diviner, Arctus, and Ureus, and black-haired Mimas, and the two sons of silver, and they had pinetrees of gold in their hands, and they were rushing together as though they were alive and striking at one another hand to hand with spears and with pines.
