What is "aesepus"

In Greek mythology, Aesepus (Αἴσηπος) may refer to:

• A son of Oceanus and Tethys, the divine personification of the river and nearby town of Aesepus (today known as Gönen in Turkey), grandfather of the other Aesepus through his daughter Abarbarea. His other daughter Phrygia was the eponym of the country Phrygia.
• The son of the naiad Abarbarea (daughter of the above Aesepus) and Bucolion. His twin brother was Pedasus; the pair appears briefly in the Iliad, Book VI. Both men fought in the Trojan War and were killed by Euryalus, the son of Mecisteus.
