Entre Meeanique et Arehiteeture: e'est-a-dire, entre les proeedes teehniques qui, depuis des temps immemoriaux eonforment l'art et la scienee de la eonstruetion au developpement de la scienee physique et mathematique la plus generale et, peut-etre, la plus abstraite, subalternata tanturn geometriae et philosophiae naturalis, eomme le disait Tartaglia, bien que liee aux faits les plus farniliers: la statique et la meeanique des mareriaux et des struetures. Le theme qui nous eoneeme est done la relation entre la technique et la scienee dans son exemple le plus important, je crois, du point de vue historiographique mais aussi epistemologique: a savoir, la relation entre le savoir faire, qui se eonforme a la norme, en respeetant une determination et une eongruenee parfaites avee son objectif, et la theorie, qui eonfirme la norme et temoigne la neeessite de la determiner eongrfiment avec les lois de la nature. Avee une extreme perspieaeite, quelque peu offusquee par une frivolite erudite, l' Abbe Franeeseo Maria Franeesehinis, mathematieien et adepte de la philosophie des lurnieres, se peneha sur la question dans un bref traite qu'il publia a Padoue en 1808 sous 1 le titre Des Mathematiques appliquees , soutenant la nouvelle tendanee didaetique introduite a l'Universite de Padoue par l'ephemere Regne d'Italie. Simulant un eonflit entre plusieurs auteurs, Franeesehinis exposait une premiere these dans un Discours inaugural qu'il reeita peut-etre reellement en 1807, lorsqu'il devint titulaire de la Chaire de Mathematiques appliquees.

This book is one of the finest I have ever read. To write a foreword for. it is an honor, difficult to accept. Everyone knows that architects and master masons, long before there were mathematical theories, erected structures of astonishing originality, strength, and beauty. Many of these still stand. Were it not for our now acid atmosphere, we could expect them to stand for centuries more. We admire early architects' visible success in the distribution and balance of thrusts, and we presume that master masons had rules, perhaps held secret, that enabled them to turn architects' bold designs into reality. Everyone knows that rational theories of strength and elasticity, created centuries later, were influenced by the wondrous buildings that men of the sixteenth, seventeenth, and eighteenth centuries saw daily. Theorists know that when, at last, theories began to appear, architects distrusted them, partly because they often disregarded details of importance in actual construction, partly because nobody but a mathematician could understand the aim and func tion of a mathematical theory designed to represent an aspect of nature. This book is the first to show how statics, strength of materials, and elasticity grew alongside existing architecture with its millenial traditions, its host of successes, its ever-renewing styles, and its numerous problems of maintenance and repair. In connection with studies toward repair of the dome of St. Peter's by Poleni in 1743, on p."
