Abstract
To make an exact definition of the "Non-Byzantine" character is an important problem for the study of religious architecture in Balkan and Russian area. In spite of general adoption of the so-called Greek-cross plan for the central part in the church, the styles of the most of these buildings which belong to the end of the 11th century on, seem to have other essential characteristics than those of the typical "Later-Byzantine". Such a distinctive feature, the native aspect in a sense, which appears on every part of these buildings, should be recognized only through the detailed analysis of following elements and factors : the general project of plan closely related with the local ceremony or riturgy, technical condition, cohice and usage of material, dimension and the formal unity as the reflection of specific condition such as the climate etc. According to these close investigations, it is possible to define the various Non-Byzantine phases of the Serbian and Russian churches and their creative intention to develop their paticular tradition.
