The gothic project of the Seville cathedral. Outline, measurement and proportion evidences

Abstract

The ground plan of the Seville Cathedral is characterized by its remarkable overall orthogonality, that was very innovative and influential in its time. A graphical analysis of the ‘Bidaurreta trace’, an unsigned drawing datable to the fifteenth century, enables an approach to the original project and to the beginnings of the Cathedral work. Moreover, new hypotheses about the authorship, date and aim of the document itself are possible.
