It's literally true: Spoiler : This is a coin issued by Offa of Mercia (died 796) after the fashion of an Abbasid dinar. That Anglo-Saxon kings could issue Arabic coins is a big lesson on the dynamics of the 8th century world. The coin also uses Latin. So if England's coinage is a Roman inheritance of later medieval Europe for the most part, it has to also be, in part, an Arabic inheritance. On that logic anyway. Of course it reflects the fact that the Arabic political spheres exerted contemporary economic and therefore political influence. There is a tendency to discuss 'dark age' civilization in northern Europe purely in terms of 'survival'/non 'survival' of Roman/Mediterranean institutions, acting like these institutions could never themselves change. The coin should remind us that Mediterranean influence was also contemporary rather than historic in Anglo-Saxon England. Bede still used Roman emperors to date affairs, but the Arab coins show that maybe the Roman Empire's contemporary models were beginning to be marginalized in terms of prestige in favour of newer 'barbarian' remakes. Was this in part because of the replacement of the Romans by the Arabs as the dominant political unit of Western Eurasia during the seventh and eighth centuries?
