After whose father was the Aegean Sea named?

The Aegean Sea is named after Aegeus, who was a king of Athens and the father of Theseus. According to Greek mythology, Aegeus was so distraught after sending his son to Crete to face the Minotaur that he mistakenly believed Theseus had died. Upon seeing a black sail instead of a white one signaling the ship's return, he threw himself into the sea, which subsequently took his name as the Aegean Sea. This name reflects the deep connection Aegeus has to the region, and the tragic narrative surrounding his relationship with Theseus further cements his prominence in the mythological tradition. Therefore, Aegeus is the correct answer as the sea is directly associated with him rather than with Theseus, Perseus, or Poseidon.
