Carceri d'invenzione

Series of prints by Giovanni Battista Piranesi

Carceri d'invenzione, often translated as Imaginary Prisons, is a series of 16 etchings by the Italian artist Giovanni Battista Piranesi, 14 produced from c. 1745 to 1750, when the first edition of the set was published. All depict enormous subterranean vaults with stairs and mighty machines, in rather extreme versions of the capriccio, a favourite Italian genre of architectural fantasies; the first title page uses the term.
