Editing Celestial globe (section)

=== 11th century ===
The earliest surviving celestial globe was made between 1080 and 1085 C.E. by [[Ibrahim ibn Said al-Sahli]], a well-known astrolabe maker working in [[Valencia]], Spain.{{sfn|Blair|Bloom|2013|pages=126, 127, 153}} Although the imagery on this globe appears to be unrelated to that in al-Sufi's The Book of the Constellations al-Wazzan does seem to have been aware of this work, as all forty-eight of the classical Greek constellations are illustrated on the globe, just as in al-Sufi's treatise, with the stars indicated by circles.{{sfn|Blair|Bloom|2013|pages=126, 127}}
