Analysis Of The Greek-Roman Isis Temple

Abstract
The Greek-Roman Isis temple is located on the west bank of Luxor; Upper Egypt was made of sandstone and decorated with different kinds of wall paintings. It suffers from many causes of deterioration and degradation mainly ground water, salt weathering, and different types of dirt accumulations on the relives and paint surface such as soot, grease, wax, biodeteriorated colored patches, bat patches, waste of birds and even house fly specks. All these lead to the gradual disappearance of paintings. In the present article we report a study on some
Nanoparticles Materials synthesized by sol-gel process to set up a cleaning system to remove a wide range of different types of organic and inorganic materials from the surface of the wall paintings
Many emperors made additions to the temple over a period of 100 years. Today all that remains of the temple is its small main building and ruins of the propylon, along with its brick enclosure wall and the well. The temple precinct had an area of 74×51 meters; the temple itself is much smaller - 13×16m. Its entrance faces east. The outer walls don't have much decoration but on the inside the reliefs are well preserved and some have
2a) due to the prolonged action of microorganisms. The atmospheric conditions of the Isis tomb have favored the growth of microorganism, in particular where higher humidity values were present. Among the macroorganisms, bats had a critical importance in the mural paintings deterioration of Isis temple. They had more destructive tools than other macroorganisms through their excretions. These excretions which contain guano, blood and urine (Fig. 2b) cause not only aesthetic damages but also physicochemical changes of the substrate that lead to irreversible loss of valuable historical stone surfaces [4]. Concentrated layer from birds dropping, bees' nests and spider web nests were noticed clearly (Fig. 2c). Also, the wall is completely covered with concentrated layer from soot and patches of waxes (Fig. 2d), resulting from burnt candles by visitors in Coptic era which caused irreversible disfigurations, changing and reducing the surface permeability. The extensive observations of the zones with ground moisture and stone shows crumbling, scaling, and the most salt efflorescences appearances (Fig. 2e). Analyses showed that chlorides and gypsum are locally concentrated and accumulated. The presence of salts had led to the detachment and flaking of the paint layer (Fig. 2f). The
