Moving the Augustan Obelisk at St. Peter's

The print shows the south flank of Old St. Peter’s, the atrium of the old basilica with Giotto’s mosaic of the Navicella on the inside entrance wall, a view into the sacristy of St. Peter’s through the wall breached to make room for the pulleys and winches used for moving the obelisk, and the new St. Peter’s under construction.
