Scale: 1:40,000,000. John Senex was a surveyor, engraver, publisher and Geographer to Queen Anne. His works include "System of Geography" (with Jeremiah Seller and C. Price), "General Atlas" folio 1708-12, Lawson's "Carolina" (1709), "England Atlas" (1714), Ogilby's "Roads" (1719), "New General Atlas" (1721), Mayo's "Barbados" (1722), Norden's "Hertfordshire" (1723), Budgen's "Sussex" (1724), "First Settlements America" (1735), and "Surrey, Sussex, Kent, Hants., and Berkshire" (1746) (Tooley, 574-6). The land of "Iesso" or "Yezo" was an island allegedly lying north of Japan. Later identified as Hokkaido, explorers in the seventeenth century were unsure of its nature. The Russians attempted to discern whether Yezo was indeed an island or part of Asia with a number of expeditions in the seventeenth century. Under the reign of Peter the Great, the explorers were able to chart Russia's Kamchatka Peninsula and the Kurile Islands. In the 1780s, a French expedition sailed between Yezo and Korea, and then, through the Kuriles (Tooley and Bricker, 130). Source(s): Tooley, Ronald Vere, ed. "The Mapping of America."
