A 1725 Roman architectural folio issued by Sebastiano Giannini, reproducing plates of Francesco Borromini's designs for the Oratory of the Roman Oratorians of St Philip Neri, aimed at architects and students. The four plates shown are engraved elevations, a capital with its plan, a doorway, and enlarged cornice and moulding details drawn in fine line with grey wash, useful for studying classical proportion and ornament.
