This is A VERY RARE separately published map of Holderness in the East Riding of Yorkshire. John Tuke’s ‘map of Holderness is of particular significance and, due to its large scale, it is possible to recognise areas which have now been eroded by the sea’ (Rawnsley). Actual distances to the sea from five villages are given but the most interesting part of the map is the identification of several towns lost to the sea noted just offshore. Some are even in the Humber Estuary. Examples are Pensthorpe, Birstall Garth, Owthorne, Sandley Meer and Auburne which amongst others have all since disappeared into the sea. Previous places washed away are also noted such as ‘Hartburn, washed away by the sea’, ‘Site of Hornsea Burton’ and others. This whole area of East Yorkshire has long been eroded by the sea, its most significant capture being Ravenser where King Henry IV landed in 1399. The town at one point rivalled Grimsby and Hull for importance. Little is known of Tuke other than that he was a land surveyor. In the following year he would publish his rare four-sheet map of the whole county. This map of Holderness includes Kingston upon Hull, Beverley and Hornsea. Rawnsley (1970) 30.
