Plastic culture in the context of olonkho semiotic systems

The Yakut heroic epic Olonkho contains valuable information about the plastic culture of Sakha, which historically developed based on national and cultural traditions, as the relationship of a Person with the outside world. The work considers ritual actions as a semiotic text with the inclusion of mnemonic-sacred symbols in it, also the rituals are considered in the context of the theory of «rites of passage», the plastic of the main character during his experience of heroic anger, as an informational and communicative sign. Human plasticity – physical action, gesture, pose, facial expressions, objects of the material world surrounding him, time and place of action, teleology and actionality make up the ritual syntax. The decoding of the main character’s sporting and hunting movements, the plasticity of the heroic anger, the combat duel reflects the multidimensional behavior of the hero as a person.
