1. Well over a thousand astrolabes and hundreds of globes, quadrants, sundials and other devices, have survived (out of which at least 150 astrolabes, a dozen quadrants and about 20 sundials are from before a.d. 1600), and more than 500 treatises written in Arabic, Persian or Ottoman Turkish on the construction and use of astronomical instruments are documented. For a checklist of Islamic instruments to c. 1500, see King David A., In synchrony with the heavens: Studies in astronomical timekeeping and instrumentation in medieval Islamic civilization (2 vols, Leiden, 2004), ii, 993–1020.
2. A good illustration of this are the inscriptions on some seventeenth-century astrolabes from Safavid Iran; see e.g. my description of astrolabe AST0594 in: François Charette, “Eastern astrolabes”, in van Kleempoel Koenraad (ed.), Astrolabes at Greenwich: A catalogue of the astrolabes in the National Maritime Museum (Oxford and Greenwich, 2006), 210–335.
