- Name origin (IAU)
- The constellation of Lupus is one of the few ancient "Greek" constellation outside the zodiac that was directly taken over from a Babylonian constellation. The Sumerian term for this creature was UR.IDIM, later alternatively written "Uridimmu" in the Akkadian language (the literal Akkadian translation of UR.IDIM would be "kalbu šegû", according to lexical lists).
