This painting is the cartoon designed for the lunette west of the vestibule of the chapel. Maratta depicts Isaiah in the act of turning to the cloud in front of which he kneels, holding a book in his hand. Isaiah, the biblical prophet, looks up toward the cloud, disperser of justice, and according to the words of the sacred text implores: “Shower, O heavens, from above and let the clouds rain down righteousness”; at his feet the other books serve as a reminder of his roles as a politician and writer.
