Abstract

The Renaissance and Baroque architecture is very well studied and nevertheless the most complicated structures that architects then used have a lack of information and research. Elliptical domes were built with profusion, but their particular way of working is not well studied yet. Even in the actuality the mathematical analysis ignore systematically these forms. This paper tries to introduce for a first time, an attempt to know something more about these structures. 1. Introduction The geometry of the ellipse is very well know from Euclides. Their use to solve the design of Roman Buildings as amphitheatres are well known. But they never was traced as true ellipses and roman architects made approximate lines by means of arches of circle (Fig. 1) as Romanesque, Byzantin
