"Among the Aesir is also counted what some call the slanderer of the Aesir or the origin of deception and the misfortune of all gods and men, he is called Loki or Loptr, son of the giant Fárbauti. His mother is Laufey or Nál, his brothers are Býleistr and Helbindi. Loki is handsome and handsome in appearance, evil in character and very changeable in behavior. He possessed much more than other men the science which is called cunning, and he achieves everything through deception. He always led the Aesir into great difficulties and often got them out of trouble with deceptive designs. (Snorri Sturluson)"
