Not too much was known about this volcanic system at that time. Between 1701 and 1740, and also around 1780, quite a number of eruptions took place under the glacier from Bárðarbungu´s caldera itself or north east of it. In 1357, after a rest of 95 years, a medium-sized eruption occurred covering large areas in Mýrdal with volcanic debris. Some scholars say this huge eruption around the time when Iceland was settled influenced some of the descriptive imagery which appears in Völuspá, the first and best-known poem within the Poetic Edda.
