Two Alternate Designs for a Pedentive 1700 - 1780

This anonymous drawing from the 18th century is a design for a pedentive, a curved triangular surface that transitions from a square base to a circular dome. The drawing showcases two alternative designs, both featuring intricate, swirling Rococo ornamentation. The artist's delicate lines and shading suggest the elaborate plasterwork that would have adorned the ceiling of a grand interior space. The drawing's inscription indicates its intended use for the "Maniera di far la Faccia Curve," or the method of constructing curved surfaces. This work offers a glimpse into the creative process of an unknown designer and the decorative trends of the Rococo era.
