About this star:

A double star, 2 and 14.3, orange and bluish.

The Arabic name for Kaus Australis is Al-Qaus, "the Southern (part of the) Bow".

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 (this star 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 the stars lamda (Kaus Borealis) and mu (Polis) for their Keeper.

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 (Robson)].

In Euphratean days it may have been Nibat Anu.

Delta (Kaus Medius), gamma (Alnasl) and epsilon (Kaus Australis), was the Akkadian Sin-nun-tu, or Si-nu-nu-tum, "the Swallow". (Allen).

Promoters of idealistic and humane ideas, promoters of mental stimuli, enterprise and a sense of justice. (Ebertin).
