This large scale map of the county of Oxford at the scale of one inch to the mile was not superseded until that of Richard Davis in 1797. This example is in the first available state; one earlier survives in just one known example. This bears the imprint lower right of Thomas Jefferys dated 1769, just two years before his death. A rare early survey of the county and the first produced on this scale. It affords great detail in displaying towns, parishes, cottages, farms, hills, parks and commons. The roads broken down into turnpike open or enclosed show distances to London. The ornate cartouche upper right features the title set in the sail of a barge with the city of Oxford shown in the background. A fine large scale plan of the City of Oxford drawn to the scale of 132 yards to the inch is included along with a dedication to the Duke of Marlborough, owner of Blenheim Palace and the Lord Lieutenant of the County.

Jefferys was involved in no less than ten large scale English counties and was one of the most influential cartographers in the publishing of large scale maps. The mid-eighteenth century saw the first fresh series of surveys since those of Saxton carried out in the 1570s. Indeed Jefferys provides a nice link as he was also a publisher of the original Saxton copper plates. Rodger (1972) no. 371.
