This study of the early Dominican ‘Peter Martyr’, an exceedingly professional contribution to the Church, Faith and Culture in the Medieval West series, provides the first overview of materials for the life of Peter of Verona since a major article of 1953, and the first ever integrated survey of the evidence, not least iconographic (exemplified in ten well-reproduced images), of his cult. Though discussion of the sources is relegated to an appendix (a companion appendix contains pertinent texts in translation), the judicious manner of Prudlo's handling of evidence inspires confidence throughout. Interest in the life of Peter of Verona, beyond the confines of the Order of Preachers, centres on his unique claim to fame: the only medieval saint whose personal origins were Catharist. The complex politics of the north Italian cities, necessary background for the life, are indicated briefly but convincingly. His cult deserves the space it receives. That is in part owing to the circumstances of the canonisation. Peter exemplifies the kind of candidate typically chosen in early papal canonisations: he was one who had struggled against heresy and the state. He also inspired a theology of the ‘triple crown’: a saint who was virgin, doctor and martyr. Peter scooped the lot, and so became ‘the Dominican's ideal Dominican’ (p. 124), sometimes to the point of marginalising the founder himself.
