Foote, Peter. The Viking achievement: the society and culture of early medieval Scandinavia [by] Peter Foote [and] David M. Wilson. London, Sidgwick & Jackson, 1970. xxv, 473 p.
This is an account of the Norsemen in the period A.D. 800-1200. To understand the Vikings, the society, technology, art, and literature of these vital people, a vast amount of evidence of very different kinds has to be considered. Some of this evidence is literary, philological, and archaeological;
parts of the evidence only came to light in 1967 and 1968 excavations; some of it has been intensively studied and argued about in a host of languages for 200 years or more.
