摘要：The Abu El Leaf Monastery, also known as Deir Abu Lifa, is considered one of the most important and famous monasteries in Fayoum Oasis, Egypt. It is located about two kilometers north of Quasr Al-Sagha Palace and about thirteen kilometers from Lake Qarun,one hundred kilometers from the capital of Egypt. [1-3].The Abu El Leaf Monastery was mentioned and founded by St. Panoukhius about 687 A.D.. Dir Abu El Leaf monastery was used almost from seventh to ninth centuries. It was seen as a safe haven for Christians seeking safety from religious persecution [4-5]. The monastery is quite rudimentary, its entrance is cut into the mountain and consists of small caves carved into cliff sides that can be difficult to reach. It has seven rooms containing some wall paintings and structures painted with some remains of pigments. Here we reported the investigations and analyses of the materials and techniques of the wall paintings in The Abu El Leaf Monastery using analytical techniques such as: Polarized light microscopy (PLM), X ray diffraction (XRD), scanning electron microscopy energy dispersive X-ray spectroscopy (SEM�EDS) and Fourier Transform Infrared Spectroscopy (FTIR). Earth materials such as iron oxides based on hematite and goethite were the main findings, black carbon was also identified. The analyses of samples from different locations of The Abu El Leaf Monastery with XRD analysis indicated the presence of calcite, anhydrite, gypsum in the ground layer,and calcite in the plaster one. The pigments were identified by close visual investigation which showed that the paint layer was a very thin one, and that some parts were in very bad conditions such as some missing parts and some fallen others. Arabic Gum as organic binding medium suggests that tempera technique was used in The Abu El Leaf Monastery in Fayoum Oases.
