"It's hard to imagine any culture without stable elements. True creation can be revealed only through comparison with the stable, single with the whole, individual with the tribal. In the narrow sense of the word the canon may be interpreted as the definite totality of rules, norms and proportions being set consciousnessly. According to M.M,Bakhtin in the broadest sense of the word the canon is the particular and dynamically developing tendency. As a rule, speaking of the "canon' they mean the narrow sense of the word. At once you can remember the Egyptian canon. The face is profiled, eyes are fronted, shoulders are fronted too, legs are profiled. It's well known from the school years. Any art work made on the base of the canon is like the text which not only initiated people can read but all members of the society without any exception. Any canon element is a sign, combination of elements within the canon have also the sign nature. The culture of a particular epoch is based on the system of canons. The canons are not so many in number, their manifestations in various arts are different as, let's say, the verses by one and the same poet translated into various languages There are two kinds of canons in the architecture: ones having the sources out of professional activity and others are so called withinprofessional canons. The appearance of the within-professional canons can be explained by history development when the architectural activity becomes the profession. It's not our aim to dwell upon the non-professional canons in this paper. It will he mentioned that both non-professional and withinprofessional canons have similar nature and they are based as a rule on the different sign systems. Within-professional systems of rules, norms and proportions are far from being understood by everyone, these systems may be rightly called elite. It's realy so."
