J.M.W. Turner: Sketchbooks, Drawings and Watercolours

This sketch depicts a view of Tivoli with the Ponte San Rocco, a wooden crossing erected upon the foundations of a previous stone structure swept away in a flood in 1808. Turner’s viewpoint is from a location near present-day Piazza Rivarola looking north towards the point where the River Aniene, tips over the edge of the gorge immediately in front of the bridge and falls away in cascades. Visible above the bridge in the centre of the composition is the so-called Temple of Vesta, a circular ruin dating from the first century BC which stands on the edge of the gorge at the north-eastern edge of the town. The campanile to the left belongs to the Chiesa di San Giorgio, a church which until the end of the nineteenth-century incorporated the ruins of the so-called Temple of the Sibyl. Similar studies can be found on folios 43–44, 63–63 verso and 77 verso (D15006–D15008, D15045–D15046, D15072). Turner also recorded the view looking towards the bridge from the opposite direction, see folios 2 verso, 3 and 89 verso (D14936, D14937 and D15096), and in the Tivoli sketchbook (Tate D15494; Turner Bequest CLXXXIII 27).

The picturesque position of the Ponte San Rocco made it a popular subject for artists, and by the early nineteenth century it was a well-established topographical motif. The vista in Turner’s sketch is similar to that in paintings by Louis Ducros (1748–1810),1 and in an engraving by Luigi Rossini (1790–1857).2 However, it is no longer possible to find the same vantage point in present-day Tivoli. A devastating flood in 1826 persuaded Pope Gregory XVI to divert the course of the river away from the residential district. Consequently, the town’s many waterfalls, including the Grand Cascade near to the Temple of Vesta, were replaced instead by the great waterfall in the Villa Gregoriana to the north-east of the town. Furthermore, the topography of the town was vastly altered and the wooden Ponte San Rocco was succeeded by the newly-built Ponte Gregoriano.
