The subject of this sketch is a view looking north towards St Peter’s and the Vatican with the Janiculum Hill on the west (right-hand side). Visible in the distance is the heights of Monte Mario crowned by trees and the Villa Mellini. Turner’s location is not conclusively identified although it appears to have been a point on the Via delle Fornaci. The composition continues on the opposite sheet of the double-page spread, see folio 76 verso (D15442; Turner Bequest CLXXXII 75a). For further sketches from the Janiculum see folio 39 verso-40 (D15369–D15370).
A separate sketch along the top of the page appears to show part of the skyline of the city with distant mountains beyond.
