This is a map showing the mouths of the Thames and the Medway from Ipswich to Sandwich and Maldon and Rochester to the sea. It dates from around 1544 and is annotated ‘Rycherd Cavendishe made this carde’. Richard Cavendish was a master gunner who had supervised new defence works at Berwick and Wark in 1522-3. The map seems to have been made with the purposes of defence and navigation in mind. Coastal forts and navigational channels are shown. The shoreline is exaggerated in order to illustrate clearly how an enemy might move ashore and how they might be stopped. In this case the enemy was England’s ancient adversary France, with whom hostilities had resumed in 1542. This map of the vulnerable south east coast, was made against this historical background. The fear of a French invasion was very real. In 1514 the French had invaded Brighton, and in 1545 French ships entered the Solent and landed on the Isle of Wight.
The lines which cover the sea areas of the map are called rhumb lines. These are lines of constant bearing that radiate from compass roses and allow the sailor to plot a course from harbour to harbour using dividers and straight edge.
Vignettes of several towns are included on this map, Sandwich, Rochester and Canterbury are shown. The view of Essex is possibly derived from a survey Cavendish made in 1520. Other settlements are formalized showing rows of red roofed houses with a church in the centre. A scale bar annotated by ‘3’ is included, however, as this occupies a green painted area it is likely that this was added later.
