纳尼亚，从峡谷到北部，与奥古斯都桥

Turner devoted a considerable number of sketches to the Bridge of Augustus (Ponte d’Augusto) at Narni, one of the most famous landmarks in Umbria, see folio 61 verso ( D14772 ). This page contains two drawings executed with the sketchbook held vertically like a notebook. Both landscapes are taken from the same viewpoint in the gorge to the north of the town, but looking in different directions. The lower sketch depicts the view looking west with Narni at the top of the slopes on the left and the monastery of San Cassiano above on the right. The upper sketch meanwhile shows the view looking east towards the Bridge of Augustus, with the town perched above on the right. This angle was the preferred composition chosen by the French painter, Jean-Baptiste-Camille Corot (1796–1875) for his celebrated outdoor studies of the bridge, executed during a sketching tour in 1826. In paintings such as The Augustan bridge at Narni , oil on paper (Louvre, Paris), Corot sought to synthesise the authenticity and spontaneity of en plein-air painting with the academic principles of the classical landscape tradition of Claude Lorrain and Poussin. 1

Also on this page is part of a horizontal landscape drawing of trees by the banks of the River Nera. This sketch continues on the opposite sheet of the double-page spread, see folio 66 ( D14781 ).
