King Agoraphobius was the ruler of Attica. He succeeded his father, King Arachnophobius. He was himself succeeded in turn by his son King Xenophobius, grandson King Oeneus and finally great-grandson King Orestes of Attica. Iolaus and Orestes speculated that Agoraphobius had had a romantic relationship with Iolaus's Great-Grandmother, Althea, which led to the two men looking so alike.
