Der Mund der Wahrheit

Rocca’s handling of light and color follows the dynamic, theatrical approach of the Baroque, while his brushwork and tonal choices hint at the later Barbizon school's emphasis on naturalistic representation, creating a blend of dramatic narrative and subdued realism.

Although Rocca was active in the early 18th century, the painting entered the Alte Pinakothek’s holdings at a later date, where it remains on display. The work has been catalogued under Rocca’s alternative names, including Parmigianino the Younger and Michele da Parma, reflecting his varied artistic identity.

Rocca’s career unfolded during a period when Roman artistic circles were heavily influenced by Pietro da Cortona’s grand manner. By adopting this style, Rocca aligned himself with the prevailing aesthetic while also contributing to the visual discourse surrounding classical motifs such as the Mouth of Truth.
