The article deals with ontological issues of creativity and mortal implied sense of Pushkin's fairy tale. The study object is the figures of Thanatos and Eros in 'The Tale of the Golden Cockerel' fairy tale. The images of King Dadon and the Queen of Shamakhan are revealed in symbiotic relationship with folklore aesthetics. Reference to folklore is caused not only by genre of the work but also by metaphysical nature of oral tradition since the Russian people have a special attitude to the theme of death. This is evidenced by the Russian fairy tale with search of "the other kingdom" in which a hero must suffer a temporary death in order to get a wonderful object, save a prophetic bride and obtain the sacred knowledge.
