Orest
In Greek mythology, Orestes (/ɒˈrɛstiːz/; Greek: Ὀρέστης ) was the son of Clytemnestra and Agamemnon. He is the subject of several Ancient Greek plays and of various myths connected with his madness and purification, which retain obscure threads of much older ones.
Orestes has a root in ὄρος (óros), "mountain". The metaphoric meaning of the name is the person "who can conquer mountains".
