Among the several examples of Islamic influences on the medieval art and architecture of the southern Italy, the mausoleum of Bohemond I in Canosa (Apulia) stands out for importance. Numerous studies have been devoted to this monument, and in particular to its famous bronze door, but still no attention has been paid to the decoration of its right leaf. A mixture of Islamic and Byzantine elements can be found in its decorative roundels, which betray the syncretic influences that built up the artistic background of Bohemond I himself.
