In the summer of 1263, Nahmanides (Rabbi Moses ben Nahman, c. 1195-1270) traveled from his home in Girona to Barcelona at the behest of King James I of Aragon (1213-1276) to debate with a Dominican Friar named Paul about specific claims concerning the Messiah in Judaism and Christianity. The two disputants, each thoroughly convinced of the indisputable truth of his own religious faith and theological interpretations, argued their positions before a panel of judges headed by James I himself. Nina Caputo's new graphic history tells the story of the Barcelona Disputation from the perspective of Nahmanides.

By combining the visual power of graphics with primary sources, contextualizing essays, historiography, and study questions, Debating Truth explores issues of the nature of truth, interfaith relations, and the complicated dynamics between Christians and Jews in the medieval Mediterranean.
