On the back-cover of the book one reads that the author “suggests that the Roman Empire, in its surviving Eastern Roman (‘Byzantine’) form, maintained a continual and sustained part in shaping the life of the West until at least the seventh century …”, and “Byzantine objects found in the West – whether they arrived through trade, diplomacy or the travels of individuals – force us to reconsider the extent and the purpose of the Eastern Roman Empire's intervention in the West, including Britain. In conclusion Dr Harris explores the idea of a ‘Late Antique Commonwealth’, extending from Britain to the Mediterranean”. From this résumé, in which the words ‘intervention’ and ‘shaping the life of the West’ figure prominently, one may conclude that the author is convinced that the Byzantine Empire in the East played an active role in the history of Western Europe.
