Thomas Malton, the Elder (1726–1801), A Rotunda in a Colonnaded Courtyard
, Pen and black ink, gray-brown wash, touches of white heightening, over traces of graphite; incised with a stylus, Purchased on the E. J. Rousuck Fund
, 1976.3
This pen and ink drawing was the design for the frontispiece of Malton's A Compleat Treatise on Perspective in Theory and Practice of 1776. The drawing has been chalked on the back and gone over with a stylus to transfer the design to an engraving plate; highly finished, it shows the flawless, uniform coverage possible with the early wash technique.
