The Foot of Jawza’ (rijl al-jawza’)
The Two Feet of Jawza’ (rijla al-jawza’)
The Foot of Jawza’ (rijl al-Jawza’) is the name attributed to each of two bright stars that represent the two feet of the female figure of Jawza’. In the earliest times, the name “Jawza’ ” referred to only the three bright stars that are lined up in the middle of the figure.
A pair of very bright blue-white stars that appear below the three stars of the Belt of Pearls. One star lies on each side of the Belt stars below them.
β ORI (Rigel), blue-white supergiant star, magnitude 0.1
κ ORI (Saiph), blue supergiant star, magnitude 2.1
The two Feet of Jawza’ rise and set one after the other about a week apart. The right-side Foot rises a couple days before the first star of the lunar station called the Neck Mark (al-han’a) rises, and sets when Thuraya (ath-thuraya) sets. The left-side Foot rises with the second star of the Neck Mark (al-han’a) and sets a couple days after the Follower (ad-dabaran) sets. Ibn Qutayba (d. 879 CE) reported that the Neck Mark was said to rise on the morning of June 23, and that Thuraya was said to set on the morning of November 13 and the Follower on November 26. On account of the precession of the equinoxes, we can expect to observe the Feet of Jawza’ setting in late December and rising in late July, as seen from the latitude of Tucson.
