Crivelli\u27s painting originally constituted the central section of a polyptych in the parish church at Porto San Giorgio, near Fermi. The crisp, sculptural forms reflect Crivelli\u27s probable training in the humanist center of Padua. Yet the manner in which Crivelli\u27s figures are modeled in light and shade also expresses a broader Renaissance concern with direct observation of nature. The artist\u27s fascination with the use of chiaroscuro to create an illusion of space and tangible substance has created an overall impression of sculptured marble. Note the diminutive donor kneeling in the lower left corner and the crown which, in the order to heighten the illusion of form, has been partly modeled in low relief.https://digitalcommons.u...
