Il mercurio errante delle grandezze di Roma : tanto antiche, che moderne
An early eighteenth-century guidebook to Rome's ancient and modern monuments, printed in Rome in 1704 by Antonio de' Rossi and sold by Gaetano Capranica, written by Pietro Rossini for travellers and readers interested in Roman architecture. The four pictures are small square decorative initials in woodcut style: a letter R with leafy vine borders, a letter I set among flowers and foliage, a letter C wrapped in a blossom and leaves, and a letter R framed by ornate scrollwork, useful for designers seeking historic capitals and border ornament.
