Hel (Old Norse: [ˈhel]) is a female being in Norse mythology who is said to preside over an underworld realm of the same name, where she receives a portion of the dead. Hel is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century. In addition, she is mentioned in poems recorded in Heimskringla and Egils saga that date from the 9th and 10th centuries, respectively. An episode in the Latin work Gesta Danorum, written in the 12th century by Saxo Grammaticus, is generally considered to refer to Hel, and Hel may appear on various Migration Period bracteates. In the Poetic Edda, Prose Edda, and Heimskringla, Hel is referred to as a daughter of Loki. In the Prose Edda book Gylfaginning, Hel is described as having been appointed by the god Odin as ruler of a realm of the same name, located in Niflheim. In the same source, her appearance is described as half blue and half flesh-coloured and further as having a gloomy, downcast appearance. The Prose Edda details that Hel rules over vast mansions with many servants in her underworld realm and plays a key role in the attempted resurrection of the god Baldr. Scholarly theories have been proposed about Hel's potential connections to figures appearing in the 11th-century Old English Gospel of Nicodemus and Old Norse Bartholomeus saga postola, that she may have been considered a goddess with potential Indo-European parallels in Bhavani, Kali, and Mahakali or that Hel may have become a being only as a late personification of the location of the same name.
