Asbolus
In Greek mythology, Asbolus (Ancient Greek: Ἄσβολον or Ἄσβόλη means "sooty" or "carbon dust") was a centaur. He was a seer and Hesiod calls him an augur (oionistes οἰωνιστής) who read omens in the flight of birds. Mythology 
Asbolus foresaw the Centaurs' battle against the Lapiths at Pirithous' wedding, and unsuccessfully attempted to prevent them from attending. The above is mentioned in Ovid's Metamorphoses,

He appears again when Heracles came to visit the centaur Pholus. Pholus opened a jug of wine for him which belonged to all the Centaurs; Asbolus saw Pholus do this and brought the other Centaurs, who, as it was proved by Pirithous' wedding, were unused to the drink. It resulted in a bloodbath in which Pholus and Chiron, as well as Nessus, met their deaths at Heracles' hands. It is said that Asbolus himself was crucified by Heracles' arrows. Namesake 
Asbolus' name was given to 8405 Asbolus, a minor planet in the outer Solar System. It belongs to the class of centaurs, whose orbits lie between Jupiter and Neptune. Notes
