In 1765, Jean-Jacques de Boissieu accompanied the young Duke Alexandre de la Rochefoucauld to Italy. This trip fuelled the artist's imagination, and for years after his return he produced etchings based on his travel sketches. This one is dedicated to his patron Duke Alexandre. The Ponte Lucano lies between Rome and Tivoli, at the point where the old Roman road, the Via Tiburtina, crosses the river Aniene. It was built to commemorate the victory of the Romans over the Lucanians, from which it derives its name. The squat, cylindrical structure adjacent to the bridge is the tomb of the Plautii, built about A.D. 15.
