moreScholars who study craft books and books of secrets in the Middle Ages can engage on internal debates about the modes of transmission or interpretations of numerous facets of these important treatises, but they can all agree on two relatively firm facts. First, in the past, technical knowledge was more an art (techne) than a science (scientia); that is, it was about doing rather than necessarily knowing for knowing's sake. To put it another way, it was decidedly not philosophia naturalis, with its emphasis on causes but rather ars practica, with an emphasis on doing and making. Second, practitioners of these arts tended to disseminate knowledge from one generation to the next more or less directly
through the apprenticeship system rather than through written texts. What this means, on both counts, is that in the Middle Ages and early modem period textbooks in the modem sense were generally unavailable, irrelevant, and simply not needed. The craft treatises, which survive then, can only represent a small fraction of the vast craft tradition, and that they were ever written down at all should give us pause to consider by whom and for what purpose.
Considering the craft of gunnery and its preserved treatises also adds another layer of interpretive difficulty: the study of the rise of gunnery overlaps chronologically with the Scientific Revolution and its historiography in a peculiar manner. For the Scientific Revolution, a traditional narrative exists of the increasing rationalization, quantification, and geometrization of nature. For the military use of gunpowder weaponry, the narrative argues that the gunners, seeking ever-more-accurate bombardment of fortifications, turned to exacting understandings of ballistic trajectories to accomplish this task. The conflation of these two narratives is that the gunners became "scientific," that is, using science in the modem sense, and by some extension, quantitative natural philosophy in the historical sense.
Focusing on the contemporary manuals, this conflation is found to be quite unfounded for gunnery before at least the later seventeenth century. The vast majority of gunners' manuals, treatises, notebooks, and manuals before the eighteenth century have much more in common with cookbooks than they do with the Principia of Newton or even The Two New Sciences of Galileo. Gunnery manuals, in particular, preserve collections of the description of a variety of substances, processes, and mixtures that provided aides memoire to the users and perhaps didactic tools for the preservation and transmission of such knowledge. This study analyzes a number of gunners manuals and notebooks for their content, range of coverage, and material knowledge, and then looks in-depth at a number of firework recipes across a number of manuals to understand the gunners' interests, background knowledge, and goals. The material demonstrates
their great felicity with material properties and substances, and at the same time a remarkable disinterest in philosophical frameworks in which these materials might have meaning (notably, alchemical connections are entirely absent, and even Scholastic terminology does not appear).
