Decoration with apostles and figurative fragment

The fragment is from the intrados of the gothic arches sustaining the rib vault of the ancient presbytery of Saint George's church in Fidenza, that someone has probably realized for Bernabò Visconti when present in Borgo San Donnino accompained by Saint George knights; the symbols of the evangelists are interrupted by a monocrome grotesque in the red background, the painting has been attribuited to Bartolomeo and Jacopino from Reggio.
