The main depiction shows Sts Dominic and Catherine of Siena, venerating an inset icon of Our Lady which is a copy of a 15th century work. Around the main depiction are fifteen miniature depictions of the Mysteries of the Rosary, which are anonymous. The overall work is 19th century, but the miniatures are thought to have been commissioned by the Dominicans for their 1728 rebuilding.
