Maghribî ASTROLABE which belonged to John Selden
Before 1654 A.D.

Unsigned and undated; the design of this astrolabe (cf. the {ain}ankabût, kursî and shackle) suggests that it was made in North Africa, probably in the 16th century or in the first half of the 17th century (cf. the astrolabes made by Muhammad b. Ahmad al-Battutî, exhibited in this case). Brass.

{ain}Ankabût for 32 stars. 8 plates. One plate is inscribed on one side, 'Latitude of Marrakesh, 31. 30'; the other side is engraved for latitude 33°, but has no indication of the latitude or place for which it was intended. The remainder of the plates bear no inscriptions whatever. One of them is engraved on one side with an az-zarqellu projection, and on the other side with a tablet of horizons of the type found in maghribî astrolabes. The other plates are ordinary plates for latitudes 0°, 15°, 22°50', 25°, 28°, 30°, 32°, 34°, 37°, 40°, 45°, and 48°.

This astrolabe belonged to John Selden (1584-1654), the jurist and antiquary, and came to the Bodleian Library with his library in 1659.
