Il Tempio Vaticano e sua origine : con gl'edifitii più cospicui, antichi e moderni, fatti dentro e fuori di esso
Il Tempio Vaticano e sua origine is a 1694 Roman architectural treatise on St Peter's Basilica, printed by Giovanni Francesco Buagni and written by Carlo Fontana with other architects for patrons and architecture students. Its engraved plates show plans, sections and elevations of the basilica, its dome and the surrounding piazza, drawn with fine hatched lines and precise lettered keys that a designer could use for classical architectural diagrams.
