Acrisius

Acrisius is presented in Greek myth as a king of Argos, son of Abas and Aglaea (or Ocalea) and twin brother of Proetus. In the genealogical and narrative tradition he rules Argos, quarrels with Proetus (initially expelling him but later ceding Tiryns), and, concerned by his lack of a male heir, consults the Oracle at Delphi. The oracle warns that he will be killed by his daughter's son; his subsequent actions to avoid this fate (imprisoning his daughter Danaë and later placing Danaë and the infant Perseus in a chest cast into the sea) form the core of his origin-story arc. Sources vary on institutional attributions: a Scholiast on Euripides calls him founder of the Delphic amphictyony, while Strabo instead credits him with regulating an already existing amphictyony.

Surviving sources furnish no physical description of Acrisius. He is represented genealogically and by role (king, father, rival) rather than by bodily attributes. The Ancient Greek form of his name (Ἀκρίσιος, Akrisios) is glossed in sources as meaning 'ill-judgment' or 'locust,' semantic notes that commentators sometimes use interpretively but which do not derive from a physical description.

Acrisius has no supernatural powers in the sources; his capacities are those of a mortal king and actor within political and familial spheres. He rules Argos, makes decisions about imprisonment and exile (notably imprisoning Danaë in a bronze chamber open to the sky), consults the Delphic Oracle, casts Danaë and the infant Perseus into the sea in a chest, and is variously credited with founding or regulating aspects of the Delphic amphictyony. His narrative role is to demonstrate the limits of human agency vis-à-vis oracular pronouncements and divine involvement.
