Carlo Maderno designed the palace at the beginning of the 17th century for Asdrubale Mattei, Marquis di Giove and father of Girolamo Mattei and Luigi Mattei. It was Maderno who was responsible for the extravagantly enriched cornice on the otherwise rather plain stuccoed public façade, the piano nobile loggia in the courtyard and the rooftop loggia or altana. For the interior of the palazzo, Pietro da Cortona was commissioned to execute the pair of compositions on the ceiling of the gallery, dating before 1626. Like others of the Mattei family, Asdrubale Mattei was an enthusiastic patron of the arts. Michelangelo Merisi da Caravaggio (better known simply as Caravaggio) is recorded as living at the palazzo in 1601. (Text based on Wikipedia).
