Bernardo Daddi was among the eminent painters of the early Renaissance. He developed a graceful, naturalistic language to represent holy figures. This half-length image of a crowned saint demonstrates his characteristically subtle modeling of the face. The saint’s rosy cheeks and lips contrast with faint shadows that articulate the contours of her nose and the slight squint of her eyes. The palm frond and bejeweled crown identify her as a martyr, possibly Saint Catherine of Alexandria, a scholar persecuted for her Christian faith, according to legend. This panel once formed part of a large altarpiece, most likely for a church in Florence.
