The Renaissance resulted in many innovations in architecture and parallel developments in techniques pertaining to drawings and sketches. Exploration of antiquity, and the dissemination of knowledge about its ideals, necessitated methods of communication and analysis. The emergence of paper as a medium to convey information was part of this exchange of ideas. As mentioned in the general introduction, attitudes toward sketching as a mode for exploration distinguished the Renaissance from traditional medieval practices. Renaissance workshops acted as educational facilities, encouraging competition and creativity. All of these factors affected architects’ media manipulation and, consequently, the manner in which they thought about architecture.
