Aeson
Father of Jason; Pelias’ seizure of power and the one-sandal oracle make his house the background to the Fleece quest.

Overview
Aeson is Jason’s father, and his presence gives the Argonaut voyage a dynastic pressure from Iolcus before the ship ever sails. Pindar’s Pythian 4 and Pseudo-Apollodorus both connect Pelias, the one-sandal warning and the Golden Fleece task. Within that pattern, Aeson represents a displaced or suppressed family line. Jason’s departure is therefore not simply youthful treasure hunting. It grows from an imbalance of royal power, danger within kinship and the hope that a perilous expedition might restore a threatened house.
