Giovanni Battista Borra, 1748. Trattato della cognizione pratica delle resistenze geometricamente. Turin, Italy
Unfortunately I couldn’t find any translations, abridgments, reeditions or reprints of the book.
The reason for this might be that apparently the treatise of Giovanni Battista Borra in 1748 was not of significant meaning for the international architecture scene. His treatise was just a collection of several known theories, which have already been published before and weren’t up to date anymore according to Olga Zoller.
