Note 517 — PART III MOSLEM FEATURES IN THE CHRISTIAN LEGENDS PRECURSORY OF THE DIVINE COMEDY
Harold Sunderland translation
According to Schirmer the Latin version is based on tenth or ninth century texts, and Zimmer even connects the legend with the Celtic story, Imram Maelduin, which on the strength of its archaic language he assigns to the ninth or eighth century. These hypotheses, which are not even shared by all Romance scholars, are far from having the positive value of a dated document such as the book of Al Jahiz.
