The danger of these daily changes between the degrees of night and day lies on the course of one day and then throughout the seasons leads to the expansion and contraction of the rocks and then weakening their cohesion and fragmentation. This is indeed the current situation of this block displayed in the hall, in addition to the fading of colors, as well as the use of a high-viscosity restoration material in the reinforcement that led to the attraction of dust and dirt and its adhesion to the surface. The color faded as a result of the lack of lighting control inside the exhibition hall, the remnants of the existing colors were blurred as a result of applying a reinforcement material with a high viscosity, which led to the attraction of dust and dirt, and then blurring the colors on the inscription. Examinations and analyzes were carried out on the block, and the results of the examination with a polarized microscope showed that it is of primitive limestone, which contains fossils and microorganisms,
