Works

Al-Asturlabi wrote some of the earliest comments on thehistory of science.These included the following comparison between the "ancients" (including the ancientBabylonians,Egyptians,GreeksandIndians) and the "modern scholars" (theMuslim scientistsof his time):

"The ancients distinguished themselves through their chance discovery of basic principles and the invention of ideas. The modern scholars, on the other hand, distinguish themselves through the invention of a multitude of scientific details, the simplification of difficult (problems), the combination of scattered (information), and the explanation of (material which already exists in) coherent (form). The ancients came to their particular achievements by virtue of their priority in time, and not on account of any natural qualification and intelligence. Yet, how many things escaped them which then became the original inventions of modern scholars, and how much did the former leave for the latter to do."
