In Dominicans, Muslims and Jews, Robin Vose sets out to revise what he sees as a widely-accepted yet unsustainable view of Dominican missionary work vis-à-vis non-Christians in the thirteenth-century Crown of Aragon. According to Vose the ‘maximalist’ (p. 8) contention that Dominicans deliberately prioritised and energetically pioneered the conversion of Muslims and Jews is simply untrue; the friars were at bottom an inward-turned institution, which sought to eliminate heresy and dissent within the Church and Christian community. This is argued through eight chapters that review the Dominican concept of mission, the establishment of the friars in the Crown of Aragon, their educational programme, missionary activity, pastoral work, foreign relations and political ties and activities in everyday life. Although there is little here by way of fresh sources or new material and some of the episodes with which he deals at length (for example the Disputation of 1263) have been studied thoroughly by previous scholars, Vose does a service by contextualising the story of the early friars and disputing some previous interpretations, and wrings out some thought-provoking observations and conclusions. Most important, his basic position appears sound. That said, the eighth chapter (on everyday life) is only seven pages long, and completely ignores the wealth of documentation housed in archives such as the Archive of the Crown of Aragon and Spain's National Historical – material which might either confirm or undermine his sketch of the first century of Dominican activity in north-eastern Iberia and the western Mediterranean. Nor does the study evince great theoretical depth; his conclusions take the narrative of conversion up to the seventeenth-century. Like the Dominican order that Vose discerns, this is very much an inward-oriented study. Nevertheless, it is a useful corrective that will be an aid to historians studying the history of Christian mission and inter-faith relations in the Middle Ages.
