The monograph presents the origin, design, evolution and development of Armenian Ornamental Art starting from the Stone Age. The research of visual and cognitive motifs in the Rock Art, ideograms, dragon and cross-stones, ceramics, architecture, clothing, carpets, household utensils, weapons, medieval Armenian manuscripts allow to identify the Armenian style (including archetypes of crosses and swastikas, six and eight-pointed stars, and many other images of plant, animal and mythological motifs), which has its impact on different ornamental styles (Egyptian, Greek, Arabic, Celtic, Nordic, Turkish, Persian) in religious and spiritual symbolism and iconography. The monograph presents an original collection of old and modern ornaments and patterns. They can be used in different applications in visual and applied art: ornamental design, book design, interior and exterior design, rug and carpet design, textile and clothing design, scenic design, architecture and web-design, computer graphic design, image design for movie and game industries and cognitive medical (neuropsychiatric) diagnostics. The collection can be used in education, creative virtual reality and capacity design.
