Saint Peter of Verona

Guercino — Giovanni Francesco Barbieri, nicknamed "the squinter" for his eye condition — was one of the most prolific and commercially successful painters of seventeenth-century Italy. This Saint Peter of Verona from around 1629 depicts the Dominican friar murdered by Cathar heretics in 1252, shown with the cleaver embedded in his skull that became his identifying attribute. The subject's violence and devotional intensity perfectly suited Guercino's dramatic early manner.

Bold chiaroscuro models the saint's upturned face with sculptural force, the raking light emphasizing both physical suffering and spiritual ecstasy. Fluid, confident brushwork in the Dominican habit creates rich tonal variation within the limited black-and-white palette.
