Read within Aquila, Mars with Jupiter

Alshain has no strong reading of its own in the tradition; like Tarazed it is taken with the constellation Aquila, sharing the nature Ptolemy gives the eagle's bright stars, Mars with Jupiter, and lending its weight to the eagle's themes of bold enterprise and command. Robson notes for it a keen mind and good fortune shadowed by some hidden trouble, in the manner of the secondary stars, but the detailed reading belongs properly to Altair, and Alshain is delineated by association. Its genuine interest is that it is a fairly near, Sun-like evolved star whose chief claim on attention is the accident of its place beside a far brighter one.

The Persian shahin underlying Alshain's name is the same word that gives the modern Persian term for the saker falcon, a reminder that the whole Altair-Tarazed-Alshain group was read as a bird by more than one tradition independently, Greek eagle and Persian falcon converging on the same three stars without necessarily borrowing from each other. Robson's brief note for Alshain draws its details largely by extension from Tarazed and Altair rather than from any distinct source treating the star on its own account, the ordinary situation for the fainter of a constellation's named flanking stars.
