Renaissance architecture on steroids
ITALIAN BAROQUE ARCHITECTURE, Piedmont; church of S. Lorenzo, 1668-80, Turin, by Guarini. "At the upper sides, Serlian windows alternate with pendentives supporting the cone-shaped tower-like dome, which consists of eight semi-circular ribs disposed so as to crate an eight-pointed star with an open octagonal space in the centre. Above this space rises a tall lantern covered by a small dome which is itself constructed of ribs."
File:Frontons. A pediment is an element in classical, neoclassical and baroque architecture, and derivatives therefrom, consisting of a gable, originally of a triangular shape, placed above the horizontal structure of the entablature, typically supported by columns. The tympanum, or triangular area within the pediment, was often decorated with relief sculpture depicting scenes from Greek and Roman mythology or allegorical figures.
