The Arcades du Capitole also known as the Galerue des Arcades is a series of 29 serigraphs (silk screen prints) on translucent material fastened to illuminated cases on the ceiling of the arcade of the Capitole building. Each serigraph measures 2.50 x 3.10 metres. The series depicts the history of Toulouse. Moretti executed 89 works from which the 29 were chosen. Moretti also installed a huge Occitan cross (cross of Languedoc) made of bronze measuring 18 metres wide and weighing 20 tons embedded in the square in front of the Capitole. This panel depicts the martyrdom of Saint Sernin. St Saturnin (Sernin) is styled as the first Bishop of Tolosa (Toulouse), died ca. 257. He was martyred in front of the (then Roman) Capitole by having his feet tied to a bull, which dragged him around Toulouse.
