Três mestres numa obra. A complementaridade dos artistas e artífices na execução do órgão de tubos da igreja do Convento de Santo Elói do Porto

This article aims to contribute to the study of socio­professional relationships between artisans from Porto, taking as a case study the execution of the pipe organ at the Church of the Convent of Santo Elói in the city of Porto. We intend to recompose the historical picture, which illustrates the construction process of the instrument itself and, especially, the execution of the case as an object of carving work and the collaboration of several masters in its execution. We also present a proposal to recognize the attribution of authorship for the gilding and painting of the organ case through the systematization and cross­analysis of documented data. The article highlights the importance of the work obligation contract as a privileged source of artistic and socio­biographical information.
