Ara

Mythology

This constellation was known to the ancient Greeks and Romans as Ara the altar. It may have originated as Tul-Ku, the holy altar from the ancient Euphrateans. It was originally in the zodiac but was later replaced by Libra. The Romans said it was the altar of Dionysus. The Arabs called it the incense burner.
