This city was named after the nymph Histiaea, daughter of Hyrieus, a son of Poseidon. He is famous for the treasure chamber he had built that, despite being locked, was found to be empty, his fortune stolen. He was unaware, the builders he had hired, Trophonius and Agamedes, had built a secret back entrance to the chamber and had used it to steal his wealth. Dumbfounded, to catch the thief, he laid a snare. Agamedes was trapped in it; Trophonius cut off his brother’s head so Hyrieus would never know the thief’s identity before vanishing himself.
