An example from the Codex Mellon.

The Morgan has posted a long series of plates online, depicting a wide range of architecture from Rome in the early 16th century. A gift from Paul Mellon, the collection has been dated to 1513.

Per the website:

Some of the most notable drawings in the Codex are related to the designs for St. Peter’s by both Bramante and Raphael, but it also records many contemporary and antique Roman structures including the Palazzo dei Tribunali and its church of S. Biagio della Pagnotta, both planned by Bramante for Pope Julius II; the interior of the Pantheon; and the elevation and cross section of the Colosseum.

Little is known about the draftsman responsible for the sketchbook. It has been variously attributed to Domenico Antonio (also called Menicantonio) de Chiarellis, a member of a family of stone carvers associated with Bramante, or to the sculptor-architect Domenico Aino da Varignana.
