This map is a part of an atlas known as the Queen Mary Atlas. Queen Mary commissioned the atlas in 1558 from the Portuguese mapmaker Diego Homen. Mary died before the atlas was finished, and after her death, the atlas was presented to Queen Elizabeth I.
This very attractive engraving by William Hole has a design that is based on the work of William Rogers for the smaller sized 1600 printing of Camden's Britannia. Neptune and Ceres flank the central roundel with a map of the British Isles
