Nice example of Tidemann's map of the region bounded by the York River , Williamsburg, James City Isle, Nansimond River, Elizabeth River, Norfolk, Cape Henry, Cape Charles, and the southern portion of Delaware, centered on the Chesapeake. The map includes soundings, rivers, islands bays, capes, and some early settlements, including Norfolk, Newport News, Sheldens, Hamton, Old Pecoson, York, Gochester, Tindles Fort, etc. Mark Tiddeman was a master of the British Vessel Tartar. From 1724 to 1728, he made soundings of the harbor of New York and the Hampton Roads area at the mouth of the Chesapeake. His charts were furnished to Mount & Page for the revised edition of the English Pilot, Fourth Book and were first issued in 1729. As noted by Morrison & Hansen, the map provides the most complete survey of the region to that date and represents an important step in the period between the Augustine Herman map of 1689 and Hoxton's map of 1735. A good copy of this map, with the usual signs of plate wear and a narrow upper margin, as is often the case. Morrison & Hansen, Fig. 15.
