After passing the village of Belforte del Chienti, see folio 23 verso (D14698), the road to Rome enters the Apennines and winds its way through ever more dramatic scenery with the mountains rising to great heights on either side. John Chetwode Eustace described the terrain in A Classical Tour Through Italy:
The grandeur of the scenery increased as we advanced; beyond the stage Valcimarra, the mountains are naked rocky and wild for some miles; on a sudden they assume a milder aspect sink in height, clothe their sides with sylvan scenery, and present on their wooded summits, churches castles and ruins, the usual ornaments of Italian mountains.1
Amongst the ruined ‘ornaments’ which Turner spotted from the road were the remains of the Rocca di Varano, a decaying fortress perched on the summit of a steep peak between Campolarzo and Camerino. The lower sketch on this page depicts a distant view of the Rocca with a bridge spanning the Chienti river in the foreground. Turner has used the sketchbook vertically to effectively convey the scale and height of the mountains. A similar view from nearby Bistocco can be found in the Route to Rome sketchbook (Tate D13866; Turner Bequest CLXXI 4a). See also folios 25 (D14701), 25 verso (D14702) and 26 verso (D14704).
