Mural painting in the main chapel and transept of the Cathedral of Santiago

Pictorial decoration covering the two straight sections of the barrel vault of the main chapel, the shell-shaped vault, and the triforium columns, extending all the way to the transept and the dome. Originally painted in 1604 by Juan Bautista de Celma, it was repainted by various artists over the centuries, the current version being attributed to Gabriel Fernández in the 18th century.
It stands out for the profusion of gilded motifs on a blue background—an early sign of the Rococo style—including numerous angels bearing banners, instruments, crowns, and various Jacobean emblems, which emphasize the significance of the space they fly over: the tomb of the Apostle.
