Liber Abraham Iudei de Nativitatibus [The Book of Nativities by Avraham the Jew]. Bound together with: Magistralis Compositio Astrolabii, by Hanrici [Henry] Bate. Venice: Erhard Ratdolt press, 1485. Latin. Incunabula.
Book containing two early astrological works (printed together originally):
* "Liber de Nativitatibus" - astrological work by "Abraham Iudei" [Abraham the Jew], attributed by the bibliographer Moritz Steinschneider and by other scholars to Rabbi Abraham Ibn Ezra. Although some scholars believed the work is a translation from the Hebrew of Ibn Ezra's "Sefer HaMoladot", apparently it is in fact a work originally written in Latin by Ibn Ezra himself, or under his supervision.
* "Magistralis Compositio Astrolabii", work on the subject of the astrolabe (a device that measures the inclined position in the sky of celestial bodies), by the Flemish philosopher, astronomer, astrologist and poet Henry Bate (1246-1310).
The works are accompanied by a number of woodcuts: decorated initials and ten astrological illustrations (including diagrams of the various houses, a diagram of the night sky, and more).
[22] leaves. Missing [8] leaves (signature B of the work attributed to Ibn Ezra, which includes a number of illustrations), 22 cm. Good condition. Worming to all the leaves. Foxing. Some ancient markings (in ink) to text margins. Cardboard binding with vellum spine and corners. Inscriptions in pencil and bookplate on endpapers.
