Saint Dominic

Niccolò dell'Arca, San Domenico, 1474, polychrome terracotta, Fondazione Cavallini, Ferrara

Dominic was the founder of the Dominican order, which he founded with the goal of forming religious communities to bring heretics back to the church.    

Some depictions of Dominic also include a dog (often with a torch in its mouth), as the word "Dominicans" is close to "Domini canes," meaning "dogs of the lord."
