A photograph of a drawing catalogued by Ruland (1876) as being then in the Thorvaldsen Museum, Copenhagen and 'perhaps a first sketch for' the almost entirely destroyed fresco The gathering of manna painted by the workshop of Raphael (c.1517-19) in the basamento of the eighth bay of the Raphael Loggia in the Vatican.
Ruland noted that this drawing is very different from the fresco executed in the eighth loggia, as depicted in a print made by Pietro Santi Bartoli (see RCIN 853675 for an impression of this print). The drawing does, however, bear strong compositional similarities to one at Christ Church Picture Gallery, Oxford (see RCIN 853684 for a photograph of this drawing), attributed to the school of Raphael, and is even closer to a print made by Agostino Veneziano (see RCIN 853683 for an impression). The Thorvaldsen Museum does hold a drawing in pencil on tracing paper (inv.no.D1126) which corresponds closely with that in this photograph, but is not entirely identical.
According to Dacos (see Bibliographic References), the basamento paintings of the Raphael Loggia in the Vatican were executed in grisaille and imitated bronze reliefs.
