Measured drawing of the lower part of the front elevation of the Rotunda of Capra by Palladio, near Vicenza by leading architect and designer Sir William Chambers (1723-1795) about 1755. The design has been trimmed along its top edge removing the roof. Although the drawing has been measured from the villa, many of the mouldings have been omitted; only outlines being shown.

Chambers was born in Sweden and died in London. He travelled widely, visiting China, and studied architecture at the Ecole des Arts, Paris, from 1749 and in Italy from 1750 to 1755. Many of his drawings from this period are contained in his important 'Franco-Italian' album, held in the V&A. Chambers moved to London in 1755 and published his influential Treatise on Civil Architecture in 1759. Chambers demonstrated the breadth of his style in buildings such as Gower (later Carrington) House and Melbourne House, London, in such country houses as Duddingston, Scotland, and in the garden architecture he designed for Wilton House, Wiltshire, and at Kew Gardens. He became head of government building in 1782, and in this capacity built Somerset House, London.
