Jacopo Palma il Vecchio
Central image in the St. Barbara Altar
Church of Santa Maria Formosa, Venice
St. Barbara is the patron saint of artillerymen, hence the canons at her feet. In the background is the tower that serves as her attribute. The palm branch signifies martyrdom. This saint is not usually shown with a crown, but there is a tendency in paintings of this period to put crowns on virgin martyrs.
