Solidi, Byzantine, Arab-Byzantine, Muʿāwiya, ʿAbd al-Malik
Seventh-century solidi displaying crosses with their main horizontals removed have often been described as Arab-Byzantine imitations of Byzantine solidi and their production attributed to either the caliph Muʿāwiya (661-80) or the caliph ʿAbd al-Malik (685-705). It is argued here that they were probably produced by Byzantine officials in c. 639 as they sought to buy their safety from the Arab conquerors of the greater Syrian region.
