Front view of the construction of the Maselles de Tasciaca (Thésée-la-Romaine). The drawing is in landscape format. It is framed in ink. Traces of watercolor and inscriptions are visible in the margins.
In the foreground, beside a pile of stones and bricks, workers can be seen preparing mortar. Donkey-drawn carts help transport the materials. In the background, workers erect the walls of the building using wooden scaffolding, ladders and a pulley system.
