The Table of Contents of En Islam iranien (1971–1973, hereafter Iranian Islam) shows that its central concern is The Word or Book, and is thus a contribution to Quranic studies. The heart of Corbin’s interest in the Quran is metaphor—or better, “metaphoricity.” While symbol is Corbin’s preferred term, an analysis of the various modes of interpretation in Iranian Islam reveals that they all share a common metaphoric dynamism. These modes are signaled by Corbin’s technical terminology: mundus imaginalis, hikaya, amphiboly, isomorphism, docetism, and music. A survey of these indicators of the metaphorical imagination will contextualize Corbin’s insistence that the Angel of Revelation is also the Angel of Interpretation, Angelus Interpres, who is, in the first place, the Angel of Humanity. It is metaphor that provides the imaginative ballast, energy, and vision, otherwise referred to as inspiration, gnosis, or revelation. The distinctive structure of metaphor is an analogue for the Path, one that begins with the known and moves towards a goal which is unknown because forgotten. These modes of metaphoricity are seen to work symphonically in the Quranic Sura of Joseph to reveal a remarkable “hidden hikaya” of the Covenant. Iranian Islam embodies in no uncertain terms Corbin’s philosophic faith in the universality of the Quran’s message for humanity especially as it is heard through a distinctive Iranian voice.
