What is "the seven sisters"

Pleiades \Ple"ia*des\ (?; 277), n. pl. [L., fr. Gr. (?)]

1. (Myth.) The seven daughters of Atlas and the nymph Pleione, fabled to have been made by Jupiter a constellation in the sky.

2. (Astron.) A group of small stars in the neck of the constellation Taurus; -- called also the seven sisters.
   --Job xxxviii. 31.

   Note: Alcyone, the brightest of these, a star of the third magnitude, was considered by M["a]dler the central point around which our universe is revolving, but such a notion has been thoroughly discounted by modern observations. Only six pleiads are distinctly visible to the naked eye, whence the ancients supposed that a sister had concealed herself out of shame for having loved a mortal, Sisyphus.

The Seven Sisters is an accessory for the 2nd edition of the Advanced Dungeons & Dragons fantasy role-playing game, published in 1995. The Seven Sisters details the fictional characters known as the Seven Sisters of the Forgotten Realms campaign setting.

The Seven Sisters was a 1915 American silent romantic comedy directed by Sidney Olcott. Based on the 1911 ensemble play Seven Sisters by Edith Ellis Furness and Ferenc Herczeg, the film starred Madge Evans, Marguerite Clark, and Conway Tearle. The film is now presumed lost.

The Seven Sisters was an 1860 musical burlesque extravaganza produced at Laura Keene's Theatre in New York which ran for 253 consecutive performances, making it a tremendous success for its time. The play debuted on November 26, 1860, and ran through August 10, 1861. Though considered "rubbish" by critics, it was an important precursor to 1866's The Black Crook.

The Seven Sisters is a 1992 novel by British novelist Margaret Drabble. The novel reflects on a mid-life crisis of an estranged Candida, when she moves to a rundown London apartment. The novel largely follows Candida's evasive and sometimes deceptive representation of events, including a epistolary section which is her "computer diary".
