Discovered at the foot of Strasbourg's cathedral in 2012, during excavations of the Argentorate camp, this fresco adorned one of the houses of the six tribunes commanding the Roman legion. The fresco is a pictorial technique that assumes a certain skill and speed of the artist. After laying a wet plaster, composed of lime and sand, the painter must quickly apply the pigments before the surface dries, so that it absorbs the colors.
