Outline coloured map of the mid-Atlantic region of the US by John Senex from his world atlas entitled “A New General Atlas” first published in London in 1721. This third state of the map, which was originally issued by Christopher Browne in ca 1692, is based on the work of Augustine Herrman, whose large, much improved map of the region was published in 1673. Now oriented to the north instead of the west as done previously, the map is centred on the Chesapeake Bay showing the provinces of Virginia and Maryland along with parts of Pennsylvania and New Jersey, which is divided between East and West Jersey. Although the Delaware Bay is clearly displayed, the province of Delaware does not yet exist and is shown as part of Pennsylvania while the Atlantic Ocean is referred to as The Sea of Virginia. The title cartouche has been re-engraved to replace Browne’s name with that of Senex, show a date of 1719 and dedicate the map to the Earle of Orkney. Blank verso. Other than some short tears to the wide, blank margins and minor offsetting of the old colour, the map is in excellent condition. 49 cm x 56 cm
