Although early Jewish authors gave thought to the concept of literary authorship, they composed virtually no separate treatises on the subject, nor in fact did they usually address it directly. Their conceptions of authorship were presented implicitly within larger discussions relating to the ultimate form of literature in their eyes, namely the Holy Bible. Sacred Scripture, of course, stood at the heart of Judaism since Antiquity, and its interpretation has always been an essential element of Jewish learning. The science and art of Bible interpretation were systematized in the medieval period by a number of key Jewish scholars, and their writings included sporadic discussions about the nature of the authorship of the various books in sacred Scripture. In what follows, we explore selected statements from this corpus that together offer a representative sample of how literary authorship was perceived in early Jewish cultures.
