Kaus Borealis

The IAU catalogue's account

Arbitrarily applied in recent times, together with the Latin distinctions of "middle," "southern," and "northern" (for λ Sgr), from the pre-Islamic Arabian (and later Arabic) constellation name al-qaus, "the Bow." For the pre-Islamic Arabians, al-qaus was marked by the curved line of stars ξ2, o, π, d, ρ and u Sgr (corresponding to what in other cultures was Sagittarius among the zodiacal signs). The Arabics used the indigenous name for the Greeks' Archer, alternatively translated as al-rami.
