Century Dictionary and Cyclopedia

1. n. In Greek myth, one of the great Olympian deities, daughter of Zeus (Jupiter) and Leto (Latona), and twin sister of Apollo. She may be regarded as a feminine form of Apollo. She chastised evil with her keen shafts and with deadly sickness, and also protected mortals from danger and pestilence. Unlike Apollo, she was not connected with poetry or divination, but, like him, she was a deity of light, and to her was attributed authority over the moon, which belonged more particularly to her kinswomen Hecate and Selene. In art. Artemis is represented as a virgin of noble and severe beauty, tall and majestic, and generally bearing bow and quiver as the huntress or mountain goddess. She was identified by the Romans with their Diana, an original Italian divinity.
2. n. In zoology: A genus of siphonate lamellibranch bivalves, of the family Veneridæ, having the pallial margin sinuous. A genus of coleopterous insects.
