• Resumen

  • This is the first description of two complete astrolabes from ‘Abbāsid Bagh-dad. One is by the enigmatic but prolific NasÐýlusand datable ca. 900-930, and the other is the first known instrument of A¬mad al-Muhandis, datable ca. 875. Both instruments and two additional incomplete ones also described here, are fully in the tradition of Abbasid astrolabes, of which close to two dozen, not all complete, are now known and published.
