Snorre the Icelander tells us that the Danes fortified Southwark with ditch and rampart, which the English assailed in vain.
One of the most useful nutritious species is Cetraria islandica, " Iceland moss," which, after being deprived of its bitterness by boiling in water, is reduced to a powder and made into cakes, or is boiled and eaten with milk by the poor Icelander, whose sole food it often constitutes.
One of them is the "Saga of Eric the Red" as found in the collection known as Hauk's Book, so called because the manuscript was made by Hauk Erlendsson, an Icelander who spent much of his life in Norway.
Later, in 1003, an Icelander, Thorfinn Karlsefni, who was visiting the Greenland colony, and who had married Gudrid, the widow of Leif's brother Thorstein, set out with four vessels and 160 followers to found a colony in the new lands.
Almost every young Icelander of sufficient means and position, and a very large number of young Norsemen, made one or more viking expeditions.
