Draughtsman: [Dawson, Robert]
Medium: Pen and ink on paper
This drawing of the area around Launceston in Cornwall displays several of the characteristic techniques of draughtsman, Robert Dawson (1771-1860). He used dense colour washes and short, hatched lines pointing in the direction of slopes ('hachures') to represent relief, combining them with numerical estimates of relative altitude. Magnetic north is decoratively indicated just off the coast at Tintagell Castle, the legendary birthplace of King Arthur, to the central left of the picture. Launceston Castle is shown at the most easterly point of the smaller inland landmass. Slate quarries are marked at Delaboule, in the centre of the left landmass, and Tresmarrow, in the centre of the right. Pencil lines are clearly visible, recording the angles between fixed points used for triangulation. The paper carries an Edmeads & Pine watermark.
