Rodrigo Gil de Hontañón and 16th-Century Building Techniques: The Cimborio Vault of Archbishop Fonseca College Chapel in Salamanca (Spain)

Rodrigo Gil is one of the greatest masters of Spanish architecture. His brilliant career is partially explained by the efficiency of his design methods and his building techniques, especially evident in his ribbed vaults. If we examine the latter as a whole, the first aspect to be noted is undoubtedly their great formal complexity. However, the detailed study discloses that rather limited geometric and building techniques are hidden behind those elaborated patterns, aimed at simplifying and making the execution more economical. In order to bring some of these devices to light, one of his best-known vaults was selected for an in-depth study. The construction of a large-scale model of it also revealed some interesting features regarding the placing of the centerings and shorings during the erection.
