The National Museum of Damascus holds a section from a fresco that once decorated the apse of the altar of the monastery's church.
"The panel portrays a winged angel whose head is surrounded by a halo of light.
The panel was executed in varying shades of brown and grey in addition to red, blue and green.
Art historians note that the iconographic facial features are those of the Archangel Michael, one of the highest and most important of the angels.
Indeed, the folds of the garments, the features of the face and the style of shading conform very closely to depictions on the third-layer paintings of the Monastery of Mar Musa al-Habashi (St Moses, the Ethiopian) which lies nearby and flourished contemporaneously.
