Bibiena was born on 18 August 1657 at
Bologna. In his decorations for the theatre and festivities, Bibiena replaced the central (vertical) axis with a diagonal axis, introducing an angular perspective. In the competition to select a design and architect for the construction of the
Karlskirche,
Johann Bernhard Fischer von Erlach was chosen over Bibiena. He returned to
Bologna in 1716, where in 1717, he was elected as a member of the
Clementine Academy. In 1731, Bibiena built the royal theatre of
Mantua (which burned down 50 years later, in 1781). He produced several books, including: :* ''L'Architettura civile'' (1711; "Civil Architecture"), later reissued under various titles :*
Varie opere di prospettiva (1703–1708; "Various Works of Perspective"). Past the age of 86, Bibiena died on 3 January 1743. == Family ==
