Contacts with the Mohammedans in Spain, and to a lesser extent in Sicily, made the West aware of Aristotle; also of Arabic numerals, algebra, and chemistry. It was this contact that began the revival of learning in the eleventh century, leading to the Scholastic philosophy. It was later, from the thirteenth century onward, that the study of the Greek enabled men to go direct to the works of Plato and Aristotle and other Greeks writers of antiquity. But if the Arabs had not preserved the tradition, the men of the Renaissance might not have suspected how much was to be gained by the revival of classical learning.
