W. Hollar The History of Imbanking and Draining of Divers Fens and Marshes 1724 (1661)
Sir William Dugdale's work on fen management was first published in 1662, with maps supplied by Wenceslas Hollar. This map of East and West Fen to the north and north-east of Boston is dated 1661, but is from the 1724 edition of the book. A few light brown marks.
