The Tubilla del Agua mural paintings reveal the artistic contacts that existed between the different territories on the Iberian Peninsula, especially between Catalonia, Aragon and Castile, since they share the same style as the paintings at Santa Maria de Taüll. They depict two angels fighting a dragon, a relatively recurrent theme in Romanesque art. Specifically it might refer to the angels' struggle against the forces of evil, as related in the Apocalypse. The figures are rendered with elegance, especially the one on the right, who would be the Archangel Michael, to whom the church where the paintings were originally located is dedicated.
