R. Avragam Ibn? Ezra (1089-1164) - philosopher, poet, mathematician and astronomer, philologist and primarily a great commentator on Scripture. He lived and worked in Muslim Spain, then was forced to leave it and wandered from Egypt to Britain. He wrote in Hebrew, Arabic and Latin. Distinguished by historical and philological thoroughness, laconic style and critical spirit, Ibn? Ezra's comments on the Torah are not only widely known - they are studied almost on a par with Rashi's comments.
