History of the star: A yellow star in the Girdle of the Chained Woman Andromeda. Arabic name Al Mi'zar (1), "The loin-cloth". Mirach was described in the Alfonsine Tables of 1521 as super mirat, from which has been derived its present title, as well as the occasional forms Mirak, Mirac, Merach, Mirar, Mirath, Mirax, etc.

Some have termed it Cingulum; others, Ventrale, from its former position in the figure, although now it is on the left hip.

In later Arabian astronomy it marked the right side of Andromeda, and so was known as Al Janb al Musalsalah, "the Side of the Chained Woman".

Beta appeared in very early Arabic drawings as the lucida of the northern of the two Fishes of Pisces, and marked the Arabic 26th manzil Al Batn al Hut, "the Belly of the Fish", or Al Kalb al Hut, "the Heart of the Fish". In this location it was Al Risha, the Band, Cord, Ribbon, or Thread, as being on the line uniting the Fishes; but this title now belongs to alpha Piscium (Al Risha).

Along with upsilon, phi, and chi Pisces, it was the Egyptian Coptic lunar station Kuton, the "Thread"; another name was Arit, an asterism indigenous to Egypt.

In astrology was a fortunate star, portending renown and good luck in matrimony.

[Star Names, Their Lore and Meaning, Richard Hinchley Allen, 1889]. 

Influences of the 26th manzil: Increases harvest and merchandise, helps travelers through danger, strengthens prisons and causes marital happiness and loss of treasure. (Robson*).

The man whose birth coincides with the rising of Andromeda from the sea will prove merciless, a dispenser of punishment, a warder of dungeon dire; he will stand arrogantly by while the mothers of wretched prisoners lie prostrate on his threshold, and the fathers wait all night to catch the last kisses of their sons and receive into their inmost being the dying breath. From the same constellation comes the figure of the executioner, ready to take money for a speedy death and the rites of a funeral pyre, for him execution means profit, and oft will he bare his axe; in short, he is a man who could have looked unmoved on Andromeda herself fettered to the rock. Governor of the imprisoned he occasionally becomes a fellow convict, chained to criminals so as to save them for execution. [Manilius, Astronomica, 1st century A.D., Book 5, p.351.]

The English translation of the myth of Andromeda as told by Manilius in Astronomica, 1st century A.D. can be found on the Andromeda constellation page.
