Samuel David Luzzatto (1800-1865), known by his Hebrew acronym Shadal, was the leading Italian Jewish scholar of the 19th century. A linguist, educator, and religious thinker, he devoted his talents above all to the interpretation of the Bible. As a master of Hebrew grammar and usage, he focused on the plain meaning of the text. Although he was a devout believer in the divinity, unity, and antiquity of the Torah, Shadal approached the text in a remarkably free spirit of inquiry, drawing upon a wide variety of sources, ancient and contemporary, Jewish and non-Jewish. As a result, his interpretations may strike even the modern reader as fresh and novel.
