Engraving of a landscape which Erich Pontoppidan (1698-1764) describes thus: 'a range of mountains of a very singular aspect, having seven high pinnacles, or crests, known by the appellation of the Seven Sisters, and which are discernable sixteen miles off at sea'. From his 'The Natural History of Norway', the only English translation of the work, published in London in 1755. Pontoppidan was Bishop of Bergen in Norway from where he researched all aspects of Norwegian natural history and ethnography. His book contains 'a particular and accurate account of the temperature of the air, the different soils, waters, vegetables, metals, minerals, stones, beasts, birds, and fishes'.
