282 ARABIC AND INDIAN DIVISIONS OF THE ZODIAC making it 199° and the other 198°. The Indian asterism totally disagrees with the lunar mansion Ghafr which is the fifteenth Arabian mansion. and which consists of three stars in the Virgin's (Kanyā) foot, according to Ulugh Beg. but in or near the balance (Tulā), according to others. 16. Viśākhā, the sixteenth nakṣatra, consists of four stars described as a festoon. All the authorities place the principal and northernmost star in 1°, 1°20′ or 1°30′ S and in 212°, 212°5′ or 213° E. The latitude seems to indicate the bright star in the Soutehrn Scale (α Librae), though the longitude disagrees (suggest- ing possibly a remote star κ Librae). Colebrooke suggests the four stars to be α ν ι Librae and γ Scorpii. The sixteenth lunar mansion according to Arabs is Zubanah or Zubāniyah according to Mohammad of Tizin, the bright star in the northern scale (β Librae). 17. Anurādhā, the seventeenth nakṣatra, consists of four stars and is described as a row of oblations in a right line. Its chief or middlemost star is placed in 3°, or 2° or 1°45′ S and in 224° or 224°5′E, thus placing it near the head of the Scorpion (Vṛścika) (δ Scorpionis) and the asterism comprises β, δ, π, and ρ Scorpionis. The seventeenth lunar mansion of Arabs is called Iklīl or Iklīlu'l- jebhah, which is said to contain 4, 3, or 6 stars lying in a straight line. Those assigned by Ulugh Beg for this mansion are β, δ, ν and π Scorpionis. Thus here the Indian and Arabian astronomers both concur exactly. 18. Jyeṣṭha, the eighteenth nakṣatra, comprises three stars figured as a ring. The principal and middlemost star is placed in 4°·3½° or 3° S and in 229°, 229°5′ or 230°E; this position indicates Antares or the Scorpion's heart (α Scorpionis), which is also the eighteenth lunar mansion, named Kalb or Kalbul'akrab. The three stars of Indian asterism may be α, σ and τ Scorpionis. 19. Mūla, the nineteenth nakṣatra, is represented by a lion's tail, and it contains eleven stars, of which the charac- teristic one, the easternmost, is placed in 9°, 8½° or 8° S and in 241° or 242° E. This probably (not exactly) indicates ν Scor- pionis. This agrees with the eighteenth lunar mansion of Arabs known as Shaulah, consisting of two stars near the Scorpion's
