San Crisogono
As private secretary to Pope Urban, among his most valuable services was that of purchasing old works of art, or commissioning new works, for that inveterate collector; among the artists he encouraged was Claude Lorrain. He was rewarded toward the end of Urban's pontificate by being raised to the purple as Cardinal-Priest of San Crisogono on 31 August 1643. He was appointed Bishop of Orvieto in 1644.
