Aubin Vouet (1595-1641), the brother of the famous Simon Vouet (1590-1649) was called upon to decorate the nave in the chapel of the Pénitents Noirs. He completed two giant works, more than six metres long, whose subject evokes the revelation of faith through the adoration of the Cross. These were most probably completed by one of Vouet's pupils, Jean Senelle. The Bronze serpent and The Invention of the true Cross (approx. 1630) are characteristic of Vouet's contribution to French painting at the beginning of the 17th century. His great effects of movement and masses, a strong pallet of fresh colours and clear light, sumptuous draperies and opulent forms, produce a sweeping composition in frieze form. Previously in the Pénitents noirs, there was also the austere Battle of the Red Rocks by Tournier, painted after he settled in Toulouse in around 1632-35. Unfortunately it is quite damaged today.
