We hereby focus the study of the Albertian column system, as part of the Digital Alberti project, a research initiative that aims to shed some light on the influence of Alberti on Portuguese architecture. Starting from Alberti’s treatise on architecture, De Re Aedificatoria, and its translation into Portuguese, Da Arte Edificatória, a generative computational model was developed that encodes Alberti’s prescriptions about the elements of the column system, as well as their proportions and shapes. This research complements the elaboration of the corresponding shape grammar on Alberti’s column system. This project is a paradigmatic example of the use of digital technology for understanding architectural tradition. The development of the referred models implied deepening the understanding of Alberti’s rules about the column elements. This in-depth analysis revealed a very coherent hierarchical structure ruling the relationships among the several elements. It also revealed that information was insufficient to inform a formal model of all them, especially the ones showing more complex geometry, such as the corinthian and composite capitals. Therefore, it can be considered that the application of digital technologies allowed to more accurately understand and reproduce Alberti’s guidelines for the art of building.
Foca-se o estudo do sistema de coluna Albertiano, no âmbito do projecto Alberti Digital, cuja investigação pretende elucidar sobre a influência de Alberti na arquitetura portuguesa. Partindo do tratado de Alberti sobre arquitetura, De re aedificatoria, e da sua tradução para português, Da Arte Edificatória, foi desenvolvido um modelo computacional generativo que codifica as instruções de Alberti respeitantes aos elementos do sistema de coluna, bem como as suas proporções e formas. A investigação complementa a elaboração da gramática da forma correspondente ao sistema de coluna Albertiano. O projecto é um exemplo paradigmático do uso de tecnologias digitais na compreensão da tradição arquitetónica. O desenvolvimento dos modelos referidos implicou um entendimento aprofundado das regras de Alberti sobre os elementos da coluna. Esta análise revelou uma estrutura hierárquica consistente que rege as relações entre os diversos elementos. Revelou também que, para uma modelação exacta de todos esses elementos, a informação fornecida por Alberti não é suficiente, nomeadamente nos casos mais complexos dos capitéis coríntio e compósito. Considera-se assim que a aplicação de tecnologias digitais permitiram compreender e reproduzir mais exactamente as orientações de Alberti para a arte da construção.Downloads
