Edda (Iceland.). Lit., “great-grandmother”of the Scandinavian Lays. It was Bishop Brynjϋld Sveinsson, who collected them and brought them to light in 1643. There are two collections of Sagas, translated by the Northern Skalds, and there are two Eddas. The earliest is of unknown authorship and date and its antiquity is very great. These Sagas were collected in the XIth century by an Icelandic priest; the second is a collection of the history (or myths) of the gods spoken of in the first, which became the Germanic deities, giants, dwarfs and heroes.
