Preobrazhenskaya square. Part.2 On the wall of the inner court of the Scientific institute I discovered a huge mosaic, made, probably, in the 1960s, just after the building works had been finished. The mosaic is damaged because of barbarous annexes made , probably, during the last decade. The image of the ensemble is much spoiled by the rubbish heap organized by its walls. Nevertheless, it is still impressive. The stones of the mosaic are large and bright, its surface is very vivid and rich, and it perfectly suits to the glass surface of the high wall above it. Soviet artists loved to invent mosaics for scientific institutes. Appealing to the abstract and figureless images of physical elements they could receive a permission to make an abstract piece. This very mosaic is divided on two parts: on the left one there are three figures of two engineers (male and female) and a worker, they all look rather heavy and absurd. In the opposite, the right part of the composition is covered with an abstraction, which looks much more picturesque and free. Glass and golden inclusions make the mosaic shining like a jewellery. It seems to me, that the author of this panno was much more excited about the right part and, probably made the figures only for the order’s will. They could also be accepted by the artist for material purposes. It is well known, that in the Soviet Union figural compositions were better paid than the abstract ones, and practical artists could take from the wall both a material gain and a professional satisfaction. Unfortunately we know nothing about this monument and its master. To get an information one would have to spend hours in the archives. It is incredible, but the general fashion for the Soviet period, that is embracing our society, does not provoke a careful attitude to the material and cultural values made by the Soviets. Art of the XX century is disappearing in front of our eyes. Some of the monuments look like ancient ruins, the others have been raped without a trace.
