From the dust jacket: "The Commentary is an essential adjunct to the facsimiles published in 1970 as The Blathwayt Atlas, Volume I: The Maps. But the Commentary is an independent reference work, too ... All forty-eight Blathwayt maps, which form what has been called the first atlas of the British Empire, are discussed in the Commentary."
