From the Greek Αλκιππη (Alkippe), which meant "mighty mare" from αλκαιος (alkaios) "mighty" and ‘ιππος (hippos) "horse". This was the name of a daughter of Ares in Greek myth. Her father killed Halirrhotis, a son of Poseidon, when he attempted to rape her, leading to a murder trial in which Ares was quickly acquitted.
