Antoine Rivalz began his training in the studios of his father Jean-Pierre, the sculptor Marc Arcis and the artist Raymond Lafage.
In 1703, he returned to Toulouse and was made painter of the city's hôtel de ville, a post he held until his death.
Rich from the varied training he had received in Toulouse, Paris and Rome, he created an original and varied style influenced by Baroque painting, classical art, 17th-century painting styles and the inheritance of the Italian masters.
For instance, his work on the door of a Pharmacy presents the same subject of the Italian "Pestapepe", usually referred to Melozzo da Forlì.
He produced a personal synthesis of them and revived the artistic life of Toulouse, choosing an aesthetic that was resolutely turned towards the 17th century, and resisted the innovations of Parisian painting.
