Feminine form of ARTEMISIOS. This was the name of the 4th-century BC builder of the Mausoleum, one of the seven wonders of the world. She built it in memory of her husband, the Carian prince Mausolus.
Meaning unknown, possibly related either to Greek αρτεμης (artemes) "safe" or αρταμος (artamos) "a butcher". Artemis was the Greek goddess of the moon and hunting, the twin of Apollo and the daughter of Zeus and Leto. She was known as Diana to the Romans.
