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
