The Pit of the Elbow (al-ma’bid)
The Pit of the Elbow is part of the Henna-Dyed Hand (al-kaf al-khadib) of Thuraya, a brilliant star cluster that was anthropomorphized as a female figure. One of two Hands, the Henna-Dyed Hand is longer than the Amputated Hand (al-kaf al-jadhma’) and features several well-defined elements.
A group of two (according to Ibn Qutayba) or one (according to as-Sufi) average stars located between the Henna-Dyed Hand and the Elbow. Ibn Qutayba’s description suggests it should be ι PER and another star near the Elbow. As-Sufi identifies the single faint star σ PER.
ι PER, yellow-white star, magnitude 4.05
σ PER, orange star, magnitude 4.35
The Pit of the Elbow sets about the time that the Brand (al-haq’a) sets. Ibn Qutayba (d. 879 CE) reported that the Brand was said to set on the morning of December 9. On account of the precession of the equinoxes, today we can expect to observe the Pit of the Elbow setting in early January and rising in the middle of April, as seen from the latitude of Tucson. (See How to Observe on the About page for more on this topic.)
The Pit of the Elbow does not figure among the rain stars.
The Pit of the Elbow is not one of the lunar stations.
