About this star:

This is beta1;and beta2 is Arkab Posterior.

Arkab and Urkab are from Al 'Urkub, translated by Ideler as the "Tendon uniting the calf of the leg to the heel", or it is the tendon on the leg just above the ankle (in either man or horse), and this coincides with their location in the figure on modern maps, as well as with their Euphratean title Ur-ner-gub, the "Sole of the Left Foot"; but Al Sufi and the engraver of the Borgian globe assigned these stars to the rear of the horse's body.

Alpha and the two betas were the Arabic Al Suradain, the two Surad, desert birds differently described, — by some as "larger than sparrows" and variegated black and white (magpies?); by others as yellow and larger than doves. (Allen).

Influence of the constellation:

The Archer is associated with the Hebrew letter Vau and the 6th Tarot Trump "The Lovers". (Robson).
