[[Abd al-Rahman al-Sufi]] was an important 10th-century astronomer whose works were instrumental in the Islamic development of the celestial globe.{{sfn|Blair|Bloom|2013|pages=125, 153}} His book, ''[[The Book of Fixed Stars]]'', designed for accuracy for the year 964, was a "description of the constellations that combines Greek/ Ptolemaic traditions with Arabic/Bedouin ones".{{sfn|Blair|Bloom|2013|pages=125–126}} ''The Book of Fixed Stars'' then served as an important source of star coordinates for makers of [[astrolabe]]s and globes across the Islamic world.{{sfn|Blair|Bloom|2013|page=153}} Similarly, it was "instrumental in displacing the traditional Bedouin constellation imagery and replacing it with the Greek/Ptolemaic system which ultimately came to dominate all astronomy".{{sfn|Blair|Bloom|2013|page=153}}
