Star Names

The Spear (ar-rumh)
The Banner of the Sky-Raiser (rayat as-simak)

The Spear was said to have been thrown by the Spear-Bearing Sky-Raiser (as-simak ar-ramih), one of the Two Sky-Raisers (as-simakan). The alternate name for this star, the Banner of the Sky-Raiser, was also common and recalled the military standard used in battle. In ancient Arabic, the term simak indicated something that was used to raise something else high up. When the Two Sky-Raisers reached the midpoint of their travels across the night sky, the uppermost one was almost at the zenith, right over your head, and the lower Sky-Raiser was almost directly below it, about halfway up the sky. The Two Sky-Raisers were the pillars that held up the canopy of the heavens.
