[2] The work depicts Jesus elevating Saint Peter to the rank of Prince of the Apostles, by simbolically giving him the keys of the kingdom of Heaven.

On the ground, lie the iconographic symbols of an open book and a sword, while in the sky, some angels, seraphs and cherubs, appear among the clouds to witness and to celebrate the event.

Saint John the Apostle, at the center, exalts the spiritual meaning of the delivery of the keys by pointing to Heaven.

[3] Constance Lavagne d’Ortigue, from the Louvre, wrote that "In this mature work, Pittoni shows a certain rigidity and takes up elements from his previous compositions such as angels in the sky.

The colors, in simple masses, almost without nuances, mark the space with a coat or a jacket, as if they served to differentiate the figures in a more categorical way."
