Star Names

The Well Rope (ar-risha’)

The Well Rope is the main rope used to raise and lower the Well Bucket (ad-dalw). Ancient Arab well buckets were made from a large leather pouch, and the ends of two intersecting, perpendicular wooden crossbars were fitted into the mouth of the pouch, forming it into a square shape. The main rope attaches to the crossbar.

Appearance

A bright orange star located to the east of the four bright stars that form the shape of a large, near-perfect square, known in modern times as the Great Square of Pegasus. The Well Rope included at least this star, but it is likely that the name more completely referred to a string of stars that extended from the Rear Crossbars of the Well Bucket through the bright stars of the modern constellation of Andromeda. A possible second Rope may be identified with a second string of stars that extends from the same point on the Bucket in a path that diverges farther to the north through Andromeda.

Modern Identification

β AND (Mirach), red giant, magnitude 2.49
The primary rope might also include α AND/δ PEG (Alpheratz/Sirrah), δ AND and γ AND (Almach). This path is designated with a bright line in the locator map above.
A possible second rope would pass from α AND/δ PEG (Alpheratz/Sirrah) through π, μ and 51 AND. This path is designated with a dimmer line in the locator map.

Timing

The star that certainly represented the Well Rope was also known as a lunar station by the name of the Fish (al-hut). Ibn Qutayba (d. 879 CE) reported that the Fish was said to rise on the morning of April 4 and set on the morning of October 5. On account of the precession of the equinoxes, today we can expect to observe the Well Rope setting in mid-November and rising at the end of March, as seen from the latitude of Tucson. (See How to Observe on the About page for more on this topic.)

Rain Stars

The Well Rope does not figure among the rain stars.

Lunar Stations

The star that represents the Well Rope is also one of the lunar stations as the Fish (al-hut). In early listings of the lunar stations, the Fish is the second station of the year. This was later changed to the 28th lunar station after the stations were adjusted to begin with the vernal equinox.
