This work analyses the evolution of iconic art from its beginning in the Byzantine period, until the time of the Russian Empire. This work is for specialists and students as it is written by one of the world's leading authorities on early Christian iconography. Icons are a fundamental element in art history, it is therefore crucial to understand how this imagery started and how it evolved through the centuries. As there are very few books on the subject, "Icons" stands out and is bound to become a reference in the subject.
