The tree, which is one of the most popular symbol appearing on the rugs, is pictured either single or as a group. In its most general sense, the symbolism of the tree denotes the life of cosmos: its consistence, its growth, proliferation, generative and regenerative processes. Briefly, it symbolize world-axis and inexhaustible life-process putting focus on multiplication, fertility, continuity and immortality. With its roots, trunk and leaves, it also symbolize the main axis of the world. It was believed that tree connected the underground world (magical world), the earth (land of human beings), and the sky (sacred world/paradise) to each other. Tree with the birds symbolized unification and recarnation. In the Christian faith, the tree denotes the Cross of Redemption and the cross which is depicted as the tree of life.
