History of the star: A double and probably binary, 3.9 and 5.5, pale green and blue, in the Knot of the Cord that binds the two Fishes of Pisces.

Alrisha is also called Okda from the Arabic Al-'Uqdah, "The knot".

Variations on Alrisha are Al Rescha, Al Rischa, Al Risha', or Ar-Risha'. This word originally may have come from the Babylonian Riksu, "Cord".

Classic Greek names were Sundesmos and Desmos. They were rendered by Cicero and others as Nodus, Nodus coelestis, and Nodus Piscium; by Pliny as Commissura Piscium; and in the 1515 Almagest as Nodus duorum filorum.

The Arabians translated these as 'Ukd al H'aitam, Okda and Kaitain.

The uniting cords, branching from alpha through omicron, pi, eta, and rho to the tail of the northernmost Fish, and through xi, nu, mu, f,  zeta, epsilon, and delta to omega that marks the tail of the one to the south, the one Ptolemy's called... "thread," Cicero called them Vincla, the "Bonds"; and the scholiast on Germanicus, Alligamentum linteum or luteum, divided by Hevelius into Linum boreum "North Line" and Linum austrinum "South Line". (Some of these terms also were applied to the star delta as marking one of the cords).

The Arabians knew these cords as Al H'ait al Kattaniyy, "the Flaxen Thread"; and Al Asma'i, about the year 800, mentioned them in his celebrated romance Antarah as a distinct constellation; but Pliny had done the same long before him.

The astrological influences of the constellation: The Fishes are associated with the Hebrew letter Pe and the 17th Tarot Trump "The Stars". (Robson). 

The astrological influences of the constellation given by Manilius:

The folk engendered by the two Fishes, the last of the signs, will possess a love of the sea ; they will entrust their lives to the deep, will provide ships or gear for ships and everything that the sea requires for activity connected with it. The consequent skills are numberless: so many are the components of even a small ship that there are scarcely enough names for things. There is also the art of navigation, which has reached out to the stars and binds the sea to heaven. The pilot must have sound knowledge of the earth, its rivers and havens, its climate and winds; how on the one hand to ply the mobile helm this way and that, and brake the ship and spread apart the waves, and how on the other to drive the ship by rowing and to feather the lingering blades. The Fishes further impart to their son the desire to sweep tranquil waters with dragnets and to display on shores which are their own the captive peoples of the deep, either by hiding the hook within the bait or the guile within the weel. Naval warfare too is of their gift, battles afloat, and blood-stained waves at sea. The children of this sign are endowed with fertile offspring, a friendly disposition, swiftness of movement, and lives in which everything is ever apt to change. [Astronomica, Manilius, 1st century AD, book 4, p.243.]
