Britannia Depicta

Britannia Depicta or Ogilby improv'd was an illustrated road atlas for Britain. It was printed in numerous editions over many decades from 1720 into the 19th century and updated with engravings by many artisans who worked from drawings of other artists. It featured strip maps.

The atlas was based on the earlier work of John Ogilby who published his Britannia, the first British road atlas drwn to scale, in 1675. Britannia Depicta was printed in 1720 by Emanuel Bowen and John Owen's firm Bowen & Owen. It was one of Bowen's earliest works.

A road atlas, it contains two hundred and seventy three road maps along with drawings of landmarks and miniature county maps of each of the counties of England and Wales. It augmented John Ogilby's original with additional historical and heraldic detail. As the atlas was printed with maps on both sides of each page, this resulted in a handier-sized book.

Cadell & Davies editions
Cadell & Davies published its own editions of the Britannia Depicta atlas over many years, with accompanying descriptions by Samuel Lysons. Engraved plates for their Britannia Depicta are dated 1803–1818.

The Quarterly Review of 1816 reported it was ordered along with Magna Britannia.

Landscapes by Joseph Farington were included in Cadell and Davies' six-volume "modernisation" of the illustrated atlas. His contributions include topographical Views in Cornwall (1814) and other views. He also depicted Devon for a 7th edition and had his drawings engraved but they were never published.
