Sebastiano Serlio (6 September 1475 – c. 1554) was an Italian Mannerist architect, who was part of the Italian team building the Palace of Fontainebleau. Serlio helped canonize the classical orders of architecture in his influential treatise variously known as I sette libri dell'architettura ("Seven Books of Architecture") or Tutte l'opere d'architettura et prospetiva ("All the works on architecture and perspective").
