Mathematicians of Islam
"In seeking to chart the courses of the stars, the astronomers of medieval Islam made use of the most comprehensive mathematics the world had known to that time. This 16th-century Persian illumination shows a group of turbaned astronomers working in their observatory with an array of instruments including compasses, a globe of the world, astrolabes, and a mechanical clock."
