Searching the collection at UB Heidelberg for words like “Romae”, “Romanae” produces some excellent results, if you know a few of the artists of the period. The drawings of G. A. Dosio have been referenced before on these pages! They come from his Urbis Romae Aedificiorum Illustriumquae Supersunt Reliquiae (1569), online here. The thumbnails of the pages are here.
On tafel 10 is the familiar image, at full size for once, of the ruins of Aurelian’s “temple of the sun” on the Quirinal, now thought to be a temple of Serapis.
On tafel 34 is a very familiar view of the Vatican rotunda, the 3rd century tomb converted into a chapel that stood by the side of Old St Peter’s, with the Vatican obelisk, buried in the earth but in its original position. This appears everywhere, and invariably in a defective form. It is wonderful to see it full size!
Only a couple of images there; but very nice to have. Again, thank you, UB Heidelberg!
