Aiton's Encyclopedia (1910)
in Roman mythology, the goddess of the moon, of the open air of the country, mountains, and forests. Since her attributes were similar to those of the Greek Artemis, the two were in later times identified. Originally, Artemis was the daughter of Zeus, and twin sister of Apollo. Apollo was the god of day, of light, of music, and of song. He was called Phoebus, the shining one, and, because of her close association with him, his sister was called Phoebe. Apollo came to be identified with Helios, god of the sun; so Artemis was identified with Selene, goddess of the moon. Thus the three distinct characters, Diana of the Romans, and Artemis and Selene of the Greeks, were gradually confounded, although in some respects stories concerning them were contradictory. For instance, Diana-at her own desire, for she had many suitors-remained a virgin, while Selene became the mother of fifty daughters. Finally, in the times of the later mythology, Diana, either on account of her character or her name, became the favorite; and the stories of Artemis or Selene or any goddess associated with the moon, as Luna and Hecate, gathered about her figure, which is most often seen in representations of art. Diana is to be identified with the witching influence of mellow moonlight. At her own request Zeus permitted her to remain unmarried, and caused thirty cities to celebrate her worship. Diana was devoted to the chase. Accompanied by her nymphs, she delighted in a forest life and in hunting. Agamemnon having unwittingly killed a stag sacred to Diana, she sent a plague upon the camp of the Greeks before Troy. She was appeased only by the sacrifice of the chieftain's daughter, whom she snatched from the altar, however, and bore away, leaving a hind in her place. She became infatuated also with the giant, Orion, whose death was brought about by Apollo through a ruse. She punished Actaeon, the hunter, for surprising her while bathing in a fountain, by changing him into a stag, so that he was torn to pieces by his own hounds. In art, Diana is represented commonly as a light-footed maiden of the chase, carrying a bow and a quiver full of arrows. One of the most renowned temples of her worship was at Ephesus. Ben Jonson's Hymn to Diana is an exquisite poem in which the poet has "seized upon the spirit of ancient song." Queen and huntress, chaste and fair, Now the sun is laid to sleep, Seated in thy silver chair, State in wonted manner keep: Hesperus entreats thy light, Goddess, excellently bright. Earth, let not thy envious shade Dare itself to interpose; Cynthia's shining orb was made Heaven to clear when day did close: Bless us then with wished sight, Goddess, excellently bright. Lay thy bow of pearl apart, And thy crystal shining quiver; Give unto the flying hart Space to breathe, how short soever: Thou that mak'st a day of night, Goddess, excellently bright.

the Roman goddess of chastity and hunting, the daughter of Jupiter and Latona, and the sister of Apollo or Phœbus, from which circumstance she is occasionally called Phebe, her usual name in heaven, as Diana was DIANA on earth. This goddess was worshiped under many forms, which were almost as numerous as the attributes ascribed to her. She was also called Triceps and Tergimina, from her three special spheres of rule; worshiped as Luna in heaven, Diana on earth, and Hècatè beneath the earth, or the Infernal Shades. 23-Vol. III-Cyc As Triceps she was painted with three heads, one of a horse, another of a dog, and the third of a virgin. As Diana she was esteemed the patron goddess of hunting and female chastity, and under a title she sometimes shared with Juno, that of Lucina, her aid was considered propitiatory to women in labor. Diana had a temperament quite as fervid as that of the other members of her august synod, as her amours with Pan, the Carian Shepherd, Endymion, and Orion, fully substantiate. She is represented with a quiver, sometimes attended with dogs, and sometimes drawn in a chariot by two white stags. She is supposed to be the same as the "Isis" of the Egyptians, whose worship was introduced into Greece under the name of Artemis, with that of "Osiris" under the name of Apollo. The most famous of her temples was that of Ephesus. DIANA MONKEY (Cercopithecus Diana), the Simia Diana of Linnæus, or Palatine-monkey of Pennant, an African species of monkey, so named from the crescent-shaped band, resembling that which poets and mythologists assign to the goddess Diana. DIANA OF POITIERS (de-ä-nä of pwä-tyā), a favorite of Henry II. of France; born in 1499, the eldest daughter of Jean de Poitiers. Married at 13, she became a widow at 32, and ere long attached the affections of the 19 years younger dauphin strongly to herself. On his accession as Henry II. (1547) Diana enjoyed great influence and did much to reform the court. She was made Duchess of Valentinois in 1548, retired from court to her castle Château d'Anet on the king's death in 1559, and died in 1566.

Known to the Greeks as Artemis . The goddess of hunting. According to Cicero there were three of the name-viz., a daughter of Jupiter and Proserpine, a daughter of Jupiter and Latona , and a daughter of Upis and Glauce. The second is the most celebrated, and all mention of Diana by ancient writers refers to her. To shun the society of men she devoted herself to hunting, and was always accompanied by a number of young women, who, like herself, abjured marriage. She is represented with a quiver, and attended by dogs. The most famous of her temples was that at Ephesus, which was one of the wonders of the world.
