Artemis (/ˈɑːrtɪmɪs/; Greek: Ἄρτεμις Artemis, Attic Greek: [ár.te.mis]) is the Greek goddess of the hunt, the wilderness, wild animals, the Moon, and chastity. The goddess Diana is her Roman equivalent.
Artemis is the daughter of Zeus and Leto, and the twin sister of Apollo. She was the patron and protector of young girls, and was believed to bring disease upon women and relieve them of it. Artemis was worshipped as one of the primary goddesses of childbirth and midwifery along with Eileithyia. Much like Athena and Hestia, Artemis preferred to remain a maiden and is sworn never to marry.
Artemis was one of the most widely venerated of the Ancient Greek deities, and her temple at Ephesus was one of the Seven Wonders of the Ancient World. Artemis' symbols included a bow and arrow, a quiver, and hunting knives, and the deer and the cypress were sacred to her. Diana, her Roman equivalent, was especially worshipped on the Aventine Hill in Rome, near Lake Nemi in the Alban Hills, and in Campania.
Hades (/ˈheɪdiːz/; Greek: ᾍδης Hádēs; Ἅιδης Háidēs), in the ancient Greek religion and myth, is the god of the dead and the king of the underworld, with which his name became synonymous. Hades was the eldest son of Cronus and Rhea, although the last son regurgitated by his father. He and his brothers, Zeus and Poseidon, defeated their father's generation of gods, the Titans, and claimed rulership over the cosmos. Hades received the underworld, Zeus the sky, and Poseidon the sea, with the solid earth, long the province of Gaia, available to all three concurrently. Hades was often portrayed with his three-headed guard dog Cerberus.
The Etruscan god Aita and the Roman gods Dis Pater and Orcus were eventually taken as equivalent to Hades and merged into Pluto, a Latinization of Plouton (Greek: Πλούτων, Ploútōn), itself a euphemistic title often given to Hades.
