This paper will consider the way pseudepigrapha functions—both authorising new text and interpreting old text through the practice of attaching a work to a prophet or divinely inspired figure. This is part of the growth of scripture and the creation of new authoritative scriptures. The practice of associating writing with an already established figure is not new to Jewish antiquity, but it becomes an essential feature of the growth of scripture and of later interpretative and mystical traditions. This paper will explore some surprising examples, such as Ezekiel the Tragedian and 4Ezra, and will integrate those newer examples into more well established illustrations of pseudepigrapha. We will also consider the reception of these texts as holy and inspired in the context of the canon debates.
