Monumento Primo arcuato del Cimiterio de Santi Marcellino, e Pietro nella Via Lauicana, inter duas Lauros, ad Sanctam Helenam.

Page 391 from the book "De Roma Sotterranea" ("Rome Underground"), by Antoine Bosio. Blank verso. With an engraving depicting a monumental arch in the early Christian cemetary of St. Marcellino. The depiction is a fisheye view and is intended to show the various paintings or carvings of Biblical scenes that decorate the arch. Among these is a nude man emerging from the mouth of a chimeric monster, and a nude man under a lattice hung with gourd vines: these illustrate scenes from the Book of Jonah. Italian text printed above and below describes the figure.
Watermark in paper; a rectangular shieldlike form with what may be an animal motif.
