bright constellation, late 14c., from Greek Oarion, name of a giant in Greek mythology, loved by Aurora, slain by Artemis, of unknown origin, though some speculate on Akkadian Uru-anna “the Light of Heaven.” Another Greek name for the constellation was Kandaon, a title of Ares, god of war, and the star pattern is represented in many cultures as a giant (e.g. Old Irish Caomai “the Armed King,” Old Norse Orwandil, Old Saxon Ebuðrung).
Orion
(ō-rī’ən)
A constellation in the equatorial region of the celestial sphere, near Taurus and Gemini. Orion (the Hunter) contains the bright stars Betelgeuse and Rigel.

Heb. Kesil; i.e., “the fool”, the name of a constellation (Job 9:9; 38:31; Amos 5:8) consisting of about eighty stars. The Vulgate renders thus, but the LXX. renders by Hesperus, i.e., “the evening-star,” Venus. The Orientals “appear to have conceived of this constellation under the figure of an impious giant bound upon the sky.” This giant was, according to tradition, Nimrod, the type of the folly that contends against God. In Isa. 13:10 the plural form of the Hebrew word is rendered “constellations.”
