Cardinal Ranuccio must have done some building in addition to the decoration of the interior. We have seen that the sketch of 1554-1560 (Pl. 42b) implies a halt in construction during the early years of his residence; but another draughtsman, who wrote a frenchified Italian, visited the palace within a few years of his death in 1565 and recorded substantial progress (Pls. 49a-b; Anonymous drawings from the former Destailleur Collection, Berlin, Ehemals Staatliche Kunstbibliothek, Hdz. 4151, fol. 97ff. Tolnay 1930, fig. 21, published the façade elevation; the remaining drawings were found by Lotz. The Berlin volumes are not sketchbooks, as they frequently are called, but a collection of French and Italian sixteenth-century drawings by several architects, similar in character and perhaps in provenance to the group now in the Metropolitan Museum). He drew measured plans of most of the existing portions of the first and second stories (Pls. 49a-b), a longitudinal section/elevation through the façade wing and court (Pl. 48b), the right part of the façade elevation (excluding the central window), and many details. We cannot clearly distinguish in this survey the portions built for Ranuccio from those completed before 1550, except at the rear of the court, where the earliest state is recorded in Pl. 42b. What appear to be nearly identical versions of some of these sketches by the same hand – with all their inaccuracies in proportion and scale – are preserved in the Albertina. Berlin fol. 99 corresponds to Albertina, Ital. arch., Rom, No. 1085r; fol. 97r to No. 1046r; fol. 97v to No. 1046v. I cannot explain, why on-the-site sketches of this sort would have been reproduced without emendation. The following summary of the sketches includes only those that bear on problems of chronology.
