Draughtsmen in front of a Waterfall at the Foot of Tivoli

Draughtsmen in front of a Waterfall at the Foot of Tivoli by Vernet from around 1752 combines the famous Tivoli cascades — one of Rome's most celebrated tourist attractions — with figures of artists sketching from nature. The subject reflects the practice of plein-air drawing that was central to landscape painters' training in Italy, where the tradition of outdoor sketching from ancient times was reinforced by the concentrated presence of hundreds of artists from across Europe who used Rome as their training ground. Vernet's oil technique carefully observed the behavior of light on water and cloud at different times of day and in different weather conditions, building atmospheric effects through careful layering of translucent glazes. The inclusion of the draughtsmen provides both narrative interest and a self-referential element — the painting depicts artists in the very act of making the kind of observational studies that Vernet himself practiced and that formed the empirical foundation of his atmospheric mastery. The waterfall itself, with its rushing water and spray, gave Vernet an opportunity to demonstrate his command of water in motion alongside his better-known calm and stormy sea subjects.

The dramatic waterfall provides a natural spectacle, the artists' figures establishing scale while Vernet renders the water's motion and spray with his characteristic naturalistic skill.
