In his research Acad. O. showed that in ancient times in the Far East, in the regions of Primorye and Priamurye, there was an independent center of primordial art. Rock carvings in the region appeared as early as in the Stone Age.
In the first part of the book, O. describes the monuments. Petroglyphs are located along the coastline on basalt blocks lying on the rocky base of a high terrace or on a sandy shore, sometimes even in the water. They are concentrated on coastal rocks and rocky outcrops, hiding under water during floods. The petroglyphs were with the same repetitive technique, namely with grooves of different depths. The repertoire of the petroglyphs is characterized with a predominance of images of anthropomorphic faces, however, there are also a small number of animals, usually in static poses, and images of waterfowl with long necks. A distinctive feature of the original artistic style of these petroglyphs is the tendency towards abstraction and ornamentalism, using of spirals, concentric circles, and ornamentation as the main form-building elements.
The second part of the book gives a historical interpretation of the Amur petroglyphs. O. traces ethnographic analogies to the Amur petroglyphs and notes their close connection with the traditional artistic work of the Amur tribes (and with their contemporary art), in which the ornament repeats the main subjects of rock carvings: masks, figures of fish, birds, snakes, and spirals.
The book is supplied with a large number of illustrations.
