Luzzatto manifested extraordinary ability from his very childhood, such that while reading the Book of Job at school, he formed the intention to write a commentary thereon, considering the existing commentaries to be deficient. In 1811 he received, as a prize, Montesquieu's "Considérations sur les Causes de la Grandeur des Romains," etc., which contributed much to the development of his critical faculties. Indeed, his literary activity began in that very year, for it was then that he undertook to write a Hebrew grammar in Italian; translated into Hebrew the life of Aesop; and wrote exegetical notes on the Pentateuch. The discovery of an unpublished commentary on the Targum of Onkelos induced him to study Aramaic.
