We do not know who the original Norse myth-makers were. We do know that the Danish historian Saxo Grammaticus (1150–1220 C.E.) was a major redactor of Germanic myths, including the Norse myths. The composers of the thirteenth-century Volsung Saga provide us with much of the heroic material of Norse mythology—the story of Sigurd, for example. But the most important redactor of Norse mythology was undoubtedly Snorri Sturluson.
