The moment when in 1912 Russian modernist Andrei Bely met Austrian occultist Rudolf Steiner was very important for the writer's further output. Bely decided to join The Anthroposophical Society and became one of the closest students of the Doctor (as the antrhoposophists called Rudolf Steiner). It defined the subject of Bely's works and marked one of the possible interpretation keys of his novels. In this article the authoress looks into 'Masks' (the second part of Moscow duology) in the context of eurythmy, ie 'visible speech', created by Steiner and his wife Marie von Sivers. Characteristic movements of the novel's heroes and repeated sequences of pronounced syllables form coded gnostic-anthroposophical scheme of the adept's initiation, ie show the way from the darkness into light.
