About this star:

A double star, of 4.7 and 8th magnitudes, yellow and blue [others say pale red], on the back of the Greater Dog Canis Major.

Aludra is from Arabic Al-'Udhrah, "The maidenhead", or "the Virgins", applied to this star along with delta, epsilon, and omnicron Canis Major; perhaps from the Arabic story of Suhail.

It was known as "Isis" by Grotius, although he admitted that gamma (Muliphein) might have been the one referred to by this title. [It might be worth mentioning that the alpha star of this constellation, Sirius, was called "Isis Sothis", of Egyptian Denderah Zodiac, and the resting-place of the soul of that goddess, although it should also be noted that the word Isis generally refers to the Moon and at times also indicated anything luminous to the eastward heralding sunrise]. (Allen).

Influence of the constellation:

It is said to give good qualities, charity and a faithful heart, but violent and dangerous passions. There is some danger from, or fear of, darkness and the night, and liability to dog bites, though the latter characteristic is probably associated more particularly with Sirius (this star). Canis Major is connected by the Kabbalists with the Hebrew letter Tzaddi and the 18th Tarot Trump, "The Moon". (Robson).
