In Greek mythology, Apollodorus gives the Minotaur the name Asterius.
The name appears in the mythographic tradition commonly called the Bibliotheca, where the creature is described as the child of Pasiphae and the Cretan Bull. The name is related to the Greek word for “star,” and some translations render it as Asterion or Asterius depending on the manuscript tradition and transliteration.
Most modern retellings simply call the creature the Minotaur, a name meaning “Bull of Minos.” That descriptive name identifies the monster by its bovine form and royal connection. Asterius is therefore easy to miss, even though it is an important literary detail.
Asterius should not be confused with Ariadne, Minos’s daughter, or Aegeus, the Athenian king. The variant spellings are transliteration differences, not entirely separate characters; the canonical answer here follows the common English form used for Apollodorus’s name.
