The sketch of figures and vases is one of a number of late drawings -- see also 1966.11:18 and 1966.11:19 -- that show vases and other objects not as isolated items, as in most sketches related to Piranesi's "Vasi, Candelabra...," but rather as elements in rough compositional sketches.
The verso has a fragmentary list of Piranesi publications in a clerical hand (see Stampfle catalogue entry cited below for a transcription). The latest of the works listed there is Piranesi's "Colonna Triana" in book form, which can be dated to 1774, giving a likely date for the list. The list of publications also includes a "Vasi, e candelabri, in one volume," which was surely an early version of what became the "Vasi, Candelabri, Cippi..." published in 1778.
On same mat as 1966.11:119.
Inscribed at right, in pen and brown ink, "Vaso Villa Medici".
