Abstract
As Hegel once said, in Byzantium, between homoousis and homoiousis, the difference of one letter could decide over the life and death of thousands. As the present essay would like to argue, Byzantine thinking was not only attentive to conceptual, but also to iconic differences. The iconoclastic controversy arose from two different interpretations of the nature of images: whereas iconoclastic philosophy is based on the assumption of a fundamental ‘iconic identity’, iconophile philosophy defends the idea of ‘iconic difference’. While the reception in the Latin West of the controversies over the image as a mere problem of referentiality of the Letter explains why its originality has remained underestimated for centuries, re-examining Byzantine visual thinking in the light of today’s ‘iconic turn’ reveals its striking modernity.
