Die Madonna mit dem Jesuskind erscheint in einer engelgesäumten Gloriole den Heiligen Petrus und Hieronymus 

Francesco Vanni's drawing presents the Madonna and Child in a celestial vision for Saints Peter and Jerome. Note the keys held by Saint Peter; these are no mere earthly objects, but the keys to the Kingdom of Heaven itself. Consider how this symbol resonates through time. The key, an ancient emblem of power and authority, unlocks not just physical spaces but also spiritual realms. The scepter, the cross, the sword; all carry a similar weight of meaning and authority. The key has appeared in various guises, from the hands of Janus, the Roman god of beginnings and transitions, to more modern uses in heraldry and corporate logos. The key taps into our collective subconscious, a potent symbol of access, control, and the unlocking of hidden potential. It’s a psychological trigger, engaging viewers on a deep, primal level. This symbol transcends epochs, reappearing, transforming, and gaining new relevance with each passing age. The key's journey is a testament to the enduring power of symbols to evolve and adapt, constantly resonating with our deepest anxieties and aspirations.
