Interior of Saint Peter's, Romec. 1754

The soaring, gilded vault of a central aisle of the inside of a church fills this horizontal painting. The ceiling of the nave curves up and away from us like a tunnel. It is lined with coffers, which have inset panels, decorated with gold. The light-filled nave angles down from the top center of the composition toward the lower left as it moves away from us. The white stone pillars supporting the barrel vault are intricately carved and decorated with pudgy, winged cherubs holding portraits of men, and aisles run parallel to the central nave to our left and right. In the side aisles, pink marble columns flank altars in chapels. At the far end of the church, the nave is interrupted where it opens into the light-filled crossing, before continuing beyond. Marking the space where the long hall of the church is intersected by a shorter arm to create a cross shape is a structure made of four twisting columns supporting a pointed canopy, all cast in bronze. Tiny men and women pray or gather in pairs and small groups along the nave. Some wear tattered clothing and others are elegantly dressed.

How it was made

Oil paint

Pigment ground in a drying oil, usually linseed. It dries slowly, so painters could blend on the canvas, build up thin translucent glazes, and rework a picture over weeks. Canvas replaced wooden panels in the 1500s because it is lighter and can be rolled.
