Fresco and wall painting



D. Winfield. Middle and Later Byzantine Wall Painting Methods. Dumbarton Oak Papers, 22, 1968, p. 70. According to Mora and Philippot, pontate are "sections of some 2 m high corresponding to the different levels of scaffolding. [...] Intonaco can extend in width to a considerable surface without joints, up to a maximum of 6 m. [Joints are] often only visible with favorable light." (P. y L. Mora, P. Philippot, 62). It seems reasonable to conclude that pontate are surfaces of flat white plaster that the mason can apply at one time. Their joints do not follow the composition of the drawing, nor does their surface area depend on the drawngs’ complexity, but only on the physical limitations of the mason to extend and even the wet plaster. Unlike giornate joints, pontate joints are only visible with racking light because the lime plaster is unpainted and the mason can easily extend the new mortar over the old and obscure the joint with vigorous movements of the trowel.
