Svyatogor is the giant-warrior in Russian mythology and folklore. His name is a derivation from the words "sacred mountain". He and his mighty steed are so large that, when they ride forth, the crest of his helmet sweeps away the clouds.
The story of Svyatogor passing appears as an episode in the larger tale of Ilya Muromets, Russia's greatest hero-warrior. Having heard of the giant's strength, Muromets comes to challenge him, despite being forewarned not to do so by pilgrims who had miraculously healed him. On the road, Ilya Muromets sees a giant asleep on a giant horse. Ilya strikes him three times with his mace, with the only result that the giant, still asleep, grabs and puts Ilya into his pocket. Eventually, the giant awakes, Ilya introduces himself and learns that the giant is Svyatogor, and they become friends and journey together.
They arrive at a giant stone coffin and both have a premonition that it is for Svyatogor. Ilya manages to lie down in the coffin first, but it appears too large for him, but it fits Svyatogor perfectly. When Svyatogor closes the lid, it seals to the coffin. Before the coffin sealed completely, Svyatogor passes part of his strength to Ilya through his breath.
