This is the Spanish rendering of the name Adrastus.
In Greek mythology, Adrastus was a king of Argos, and leader of the Seven against Thebes.
Because of an oracle, Adrastus married his daughters to the exiles Polynices and Tydeus and promised to restore them to their homelands. He first assembled an army to place Polynices on the throne of Thebes, led by seven champions, famously called the Seven against Thebes. The expedition failed and all the champions died except Adrastus, saved by his horse. He went with the Epigoni, the sons of the Seven, in the successful second war against Thebes, and was said to have died on his way home.
