About this star:

A yellow star in the Bow of Sagittarius (northern). The Arabic name for Kaus Borealis is Al-Qaus (1), "the Northern (part of the) Bow".

With mu (Polis) it may have been the Akkadian Anu-ni-tum, said to have been associated with the great goddess Istar.

In ancient Arabia the two small groups of stars now marking the head and the vane of the Archer's arrow were of much note as relics of still earlier asterisms, as well as a lunar station. The westernmost of these, — gamma (Alnasl), delta (Kaus Medius), epsilon (Kaus Australis), and eta — were Al Na'am al Warid, the Going Ostriches; and the easternmost, — sigma (Nunki), zeta (Ascella), phi, chi, and tau, — Al Na'am al Sadirah, the Returning Ostriches, passing to and from the celestial river, the Milky Way, with this star lamda (Kaus Borealis) and the star mu (Polis), as their Keeper; Ra'i al Na'aim, the "Keeper of the Na'ams", or Al Thalimain, meaning desert birds.

All of the foregoing stars were included in the Arabic 18th manzil, Al Na'am. [Influences: Helps the taming of wild beasts, strengthening of prisons, destroys the wealth of societies and compels a man to come to a certain place. With Moon transiting here; build, ask favors but do not marry]. (Allen).
