Abstract
As the Chronography of Theophanes the Confessor includes a lot of information about the
foreign states and tribes which were connected with the Byzantine Empire. It is legitimate, in the
Author’s view, to analyse the account concerning Islam and the Arabs by this Byzantine author. Theophanes
possessed detailed knowledge of the Arabs, Islam and Umayyad caliphs. He used, although
presumably indirectly, some Muslim sources in his work. The argument which strongly proves this
hypothesis is his precise description of inner clashes between the members of the ruling house, as
well as of Arab civil wars. The article discusses how Theophanes (and presumably his sources) depicted
not only the Arabs as an entity, but also the prophet Muhammad and some of the Umayyad
caliphs (Muawiya, Walid I, Umar II, Hisham, Marwan II).
