In 1894, Grivolas invited his youngest brother, Antoine Grivolas, a still-life painter, to leave his home on the Côte d'Azur and join him at his home near Mont Ventoux, where they lived like shepherds while making sketches. The following year, they moved to Monieux, a small village at the entrance to the Gorges de la Nesque. They spent the next season at Ventouret, near Aurel, attempting to capture the colors of the mountain landscape. A street in Avignon has been named after him.
