Aegean
the sea named for a king
Today this word meansThe sea between Greece and Turkey.
The best-known explanation derives it from Aegeus, the Athenian king who threw himself into the sea believing his son was dead.
The explanation circulated in antiquity too; Plutarch recorded it as fact.
Worth noting
But the etymology is not settled. Rival views — from aiges, meaning waves, or from the Amazon queen Aegea — existed alongside it from ancient times.
