Abstract
It is well known that Polenis analysis of the dome based on the catenary principle, included in his Memorie (1748), was the first time that the safe theorem of the Limit Analysis was applied to a masonry structure. However, his manuscripts are not so well known as the Memorie but they are very interesting because Poleni solved the problem of the dome in these documents. No quantitative structural analysis was included in the manuscripts, but when he left Rome, he gave Vanvitelli, main architect of the basilica, orders about the number, location and dimensions of the iron rings to put around it during the summer of 1743. His Memorie served as a record of the process of study and restoration of the dome though included his detailed analysis of the stability of the dome, but the new rings had been around the dome since 1743. In his manuscripts Poleni wrote about the theory of vaults that was developing at that time but it seems another case where practice prevailed over the theory.
