Speculum Romanae Magnificentiae: Longitudinal Section Showing the Interior of Saint Peter's Basilica as Conceived by Michelangelo (Published in 1569)

Art Historical Context

This striking print by Etienne DuPérac captures Michelangelo’s visionary design for the interior of Saint Peter’s Basilica in Rome. Created as part of the *Speculum Romanae Magnificentiae*—a celebrated 16th-century collection of views documenting Rome’s ancient and modern wonders—the etching with engraving presents a longitudinal section that reveals the soaring nave, dramatic lighting effects, and harmonious proportions Michelangelo conceived after taking over the project in 1547. Though the basilica’s construction spanned decades, this image preserves the architect’s bold ideas for a unified, awe-inspiring space centered on the great dome. DuPérac’s precise technique blends the fluid lines of etching with the crisp detail of engraving, allowing viewers to appreciate both the architectural grandeur and intricate ornamentation. Produced between 1558 and 1561 and published in 1569, such prints played a vital role in spreading Renaissance architectural ideals across Europe at a time when few could travel to Rome. Today, the work offers modern visitors an intimate glimpse into how one of history’s greatest artists reimagined the heart of Christendom.
