Yes, Nando, it's true that the first gunners were looked at with a mixture of awe and fear, for having this powerful and frightening thing in their hands, whose noise, fire, and sulphurous stench suggested ties to the Devil. But it wasn't long before modern science began to take over and thus we see the huge advances in artillery design and practice during the 16th cent. all over Europe. We must look to Renaissance Italy as the starting point:
1. Metallurgy and metal fabrication -- Vanoccio Biringuccio's
Pirotecnica (1540) is a lucid and detailed compendium of 10 books, over 400 pages' worth in a modern English translation, of the state of the art as of the first half of the century. Book VI, of 10 chapters, covers gun- and bell-founding with tables of standard sizes and weights, and Book VII covers furnaces and molds, and also the making of cannon-balls and the designs of cannon carriages. The author (born 1480) who devoted his adult life to working in the metals industry, including the casting of large cannon. This book is a landmark in technical writing, standing out for its just-the-facts prose, avoiding the inclusion of lore and superstition, as well as flowery allusions to classical mythology, which characterised the literature of the era. The work has seen several editions through the centuries, including partial translations into other languages including Latin and Spanish.
2, Mathematics: Gunners had to do more than just be able to count. During the first half of the 16th cent., the practice became more science than art with the development of powerful tools created by the Venetian mathematician Niccolò Fontana "il Tartaglia" (his nickname The Stammerer came from a speech impediment caused when a French soldier cut his head with a sword when as a kid he had the misfortune of being in a war zone). Tartaglia revolutionized the study of ballistics when he, an avid student of the Greek thinkers, was able to prove mathematically that a projectile traveled in a parabolic trajectory. Not, as Aristotle posited, going straight through the air and then dropping abruptly to earth when its inertia was spent and gravity took over. From this, he was able to calculate the correlation of projectile range to barrel elevation, all else being equal. The figures were compiled into books of tables which became must-have field references for gunners all over the Western world and were disseminated to Eastern armies whose artillery corps were coached by mercenary trainers from Portugal and elsewhere. Tartaglia's studies were also the bases for the invention of several devices for the accurate aiming of cannon, the most important being the gunner's quadrant, which had a service life of over 3 centuries, and which is depicted in military manuals and art from as far away as India and China.
