Ceiling painting

The picture shows the ceiling of the Sala dell'Aurora, the central room on the ground floor. It was painted by Guercino depicting Aurora on Her Triumphal Chariot. This composition was a deliberate response to Guido Reni's Aurora in the Palazzo Pallavicini-Rospigliosi in Rome. Guercino's coworker was Agostino Tassi who was responsible for the architecture (quadratura) painted in fresco technique. (Guercino painted in tempera instead of fresco.)
