 Gregory the Great had a mosaic portrait of his parents executed at the monastery of Saint Andrew; it is minutely described by Johannes Diaconus ("P.L.," LXXV, 229-30).Silvia was portrayed sitting with the face, in which the wrinkles of age could not hide the beauty; the eyes were large and blue, and the expression was gracious and animated.The veneration of Saint Silvia is of early date.
