Sleypnir (OI. Sleipnir, lit. "sliding") - magical eight-legged horse of Odin. The greatest and fastest of all horses on earth. The gray horse of Odin had a remarkable ability - he could move between worlds. Descend into the sad realm of the dead and ascend the rainbow bridge to Asgard, the heavenly abode of the gods for the eight-legged horse was not difficult. Teeth Sleipnir were carved runes - ancient symbols with magical powers. In Speeches Sigrdrifa, Valkyrie Sigrdrifa (eng. Sigrdrifa) tells the hero Sigurd that "runes adorned... Sleipnir teeth and sliding undercut".

According to legend, made one day, the gods of the stranger agreed that he will build a wall around Asgard the wall without any help wall over the winter. The only horse he could use - Swaldiphary. But was that masked man really is a giant, and his horse stood a huge weight. But the gods did not know this, and as payment for the construction was a stranger to the sun, the moon and the goddess of beauty Freya. The gods were confident that the construction will not be completed in time and agreed. But soon they realized that the conditions are fulfilled, and they did not want to perform the oath. Then had Loki, because the Treaty was signed on his advice, turning into a beautiful Mare to distract the stranger from the construction, because without a horse he could not transport stones for wall. So Asgard freed from his promise. While Loki became the father of the foal of Svadilfari. And there was no better horse nor the gods, nor the people, nor the Jotuns. The foal named Sleipnir, and Loki gave it to Odin. One first saw Sleipnir, when he was still a colt, was led on a rope Loki. One admired the young horse, and Loki gave him Sleipnir. This is the perfect horse for God, no one can overtake. The Sleipnir could go everywhere, be carried on the waves of the ocean and race on the rainbow.
