El espacio ilusorio barroco en las perspectivas arquitectónicas de Girolamo Curti y Angelo Michele Colonna en el Palacio de la Ciudad de Bolonia = The illusory baroque space in the architectural perspectives of Girolamo Curti and Angelo Michele Colonna at the town hall of Bologna

The research describes the projective principles of illusory space of the Bolognese School through the representation of the architectural perspectives of Girolamo Curti (1575-1632) and Angelo Michele Colonna (1604-1687) at the town hall of Bologna. In 1627 Cardinal Bernardino Spada was commissioned by Pope Urban VIII to drive the Bolognese delegation; he started the renovation of his apartments through the illusory artifice of perspective. In addition to the sala Urbana and the sala del Dentone, Colonna, a pupil of Curti, will become the protagonist of a long artistic season; he was also active in Spain where at the initiative of Diego Velázquez, he worked at the Court of Philip IV. Returned from Madrid he left his last masterpiece painting on the ceiling of the Council Hall. The operative methodologies of “sotto in su” perspective, here presented, are based on the rigorous representation of the illusory space.
