D.O. Hill’s early lithographic views of Perthshire is a work that presaged his connection with Robert Adamson and photography. While still a teenager, Hill applied the new technique of lithography to producing this work which was issued in six parts between 1821 and 1823 by his father Thomas Hill, a publisher and print seller in Perth. Hill went on to study in Edinburgh at the Trustees’ Academy School of Design under Andrew Wilson, a landscape painter and well-known art connoisseur. Although Hill depicted Scottish peasantry in his works, it was the subtle strength of his landscape paintings on which he rapidly built his reputation. These landscapes were admirably suited to engraving, the early nineteenth century’s most influential development in the distribution of images, and many of his paintings are best-known through the engravings made from them — he had more works engraved than any other Scottish artist. Sketches of Scenery in Perthshire is, generally recognized as the earliest series of views to have been produced in Scotland by the lithographic process.
