Giovanni Battista Piranesi, Untitled etching (called "The Drawbridge")

Plate VII (of 16) from the series The Imaginary Prisons (Le Carceri d'Invenzione), Rome, 1761 edition (reworked from 1745).

The Prisons (Carceri d'invenzione or 'Imaginary Prisons'), is a series of 16 prints produced in first and second states that show enormous subterranean vaults with stairs and mighty machines.

These in turn influenced Romanticism and Surrealism. While the Vedutisti (or "view makers") such as Canaletto and Bellotto, more often reveled in the beauty of the sunlit place, in Piranesi this vision takes on a Kafkaesque, Escher-like distortion, seemingly erecting fantastic labyrinthian structures, epic in volume, but empty of purpose. They are cappricci -whimsical aggregates of monumental architecture and ruin.

The series was started in 1745. The first state prints were published in 1750 and consisted of 14 etchings, untitled and unnumbered, with a sketch-like look. The original prints were 16” x 21”. For the second publishing in 1761, all the etchings were reworked and numbered I–XVI (1–16). Numbers II and V were new etchings to the series. Numbers I through IX were all done in portrait format (taller than they are wide), while X to XVI were landscape (wider than they are high).
