284 ARABIC AND INDIAN DIVISIONS OF THE ZODIAC
and γ Aquilae. According to Arabs, the twenty-third lunar
mansion is Balā, which consists of two stars in the left hand of
Aquarius. Here again Arabian and Hindu divisions are at
variance.
24. Dhaniṣṭhā, the twenty-fourth nakṣatra, is represented
by a drum or tabor. It comprises four stars, the westernmost
of which is placed in 36° N and according to Brahmagupta,
Śiromaṇi and the Sūrya-Siddhānta in 290° E (Grahalāghava
gives 286°). This longitude of the circle of declination and the
distance of the star on it from the ecliptic indicate the Dolphin :
and the four stars are α, β, γ and δ Dolphini. The correspond-
ing lunar mansion of Arabs is Sāud, which comprises two stars
in Aquarius (β and ζ Aquarii). Here again the two divisions
disagree completely.
24. Śatabhiṣak, the twenty fifth nakṣatra, is a cluster of 100
stars figured by a circle. The principal or the brightest has no
latitude; or only a third, or at utmost half, a degree of south
latitude; and longitude 320°. This best corresponds with λ
Aquarii. According to Arabs, the twenty-fifth lunar mansion
is known as Akhbiyah which consists of three stars only, placed
in the wrist of the right hand of Aquarius. However, it appears
from Ulugh Beg's tables, as well as from Mohammad of Tīzīn's,
that four stars are assigned to this mansion. The Indian and
Arabian systems of division differ considerably but less widely
according to some.
26. Pūrva-Bhādrapada, the twenty-sixth nakṣatra, consists
of two stars represented by a couch or bed, or else by a double
headed figure, one of which is placed in 24° N and 325° or 326°
E. The only conspicuous star nearly in that position is the bright
star in Pegasus (α Pegasi) and the other may be the nearest
considerable star in the same constellation (ζ Pegasi). The
twenty-sixth Arabian lunar mansion is Mukaddim, consisting
of two brightest stars in Pegasus (α and β). Here the Indian
and Arabian divisions show concurrence.
27. Uttar-Bhādrapada, the twenty-seventh nakṣatra, consists
of two stars, figured as a twin or a person with double face, or
else as a couch. The position of the most northerly of the two
