Hubert Robert (1733–1808)

 
Roman Sketchbook, 1760.
"This sketchbook dates from Robert's student days in Rome and contains thirty-nine leaves. It includes both straightforward recordings of Roman monuments as well as many pen and wash drawings that are imaginary variations on Roman monuments.
Mostly pen and brown ink and brown wash, some sketches in black chalk, also in lead, a few in red chalk, and several in watercolor, over slight indications in black chalk, on paper."
