the number and movements of the celestial spheres; of the
time differences in days and nights in the various parts of the
earth; of the movements of sun and moon; of the solstices, the
neomeniæ, the eclipses, and the leap-years; it contains as well
astronomical tables (an ephemeris) and a perpetual calendar. It
also deals (iv, § 17) with the chronological systems of other
nations and religions, especially Christianity; and gives (iv, § 18)
in chronological order the noted personages of the Biblical,
Talmudic, and geonic periods, following the Sefer ha-Qabbalah
ofAbraham ibn Daud. This last was included by Zacuto in his
Sefer ha-Yuḥasin.
