Page "Sefer haYashar (midrash)" Paragraph 7

Although there remains doubt about whether the 1552 " edition " in Naples was ever truly printed, the study of Joseph Dan professor of Kabbalah at the Hebrew University of Jerusalem in the preface to his 1986 critical edition of the 1625 text concludes, from the Hebrew used and other indications, that the work was in fact written in Naples in the early sixteenth century.

The Arabic connections suggest that if the preface to the 1625 version is an " exaggeration ", it was then probably written by a Jew who lived in Spain or southern Italy.
