DANTE AND ISLAM, ALLEGORY by Casalino Pierluigi, Laigueglia, 1949

As concisely formulated in Dante's famous letter to Can Grande della Scala, allegory embraces four levels of meaning: the literal, the typological, the moral and the anagogic. This interpretative is not historical relevant to Islamic texts, but analogous Islamic  models of hermeneutical analysis do exist.
