The Viking Heart, the latest work by the historian Arthur Herman, is engaging, informative, and highly readable. As Herman deals with four separate topics each of which deserves a book of its own, it is also an extremely ambitious undertaking. His reach may some­times exceed his grasp, but even when that is the case the results are likely to leave readers wanting more — in a good way.

The first topic, taking up a third or so of The Viking Heart’s text, is a history of the “classic” Viking era. The second is a discussion of what happened next — the Vikings did not just vanish into nothingness when the longships ceased setting sail. The third touches on the Scandinavian experience in America. The fourth, which is more of a thread running through the book, is an examination of what Herman dubs “the Viking heart,” character traits (mercifully somewhat evolved since that heart began beating) that, in his view, contributed so much to the development of these northern peoples and the impact they have had far beyond the fjords, forests, and lakes of their homelands.
