Abstract

A finished sketch for a light-and-shadow projection device by the Paduan mechanical artisan Johannes de Fontana (c.1395–1455), in his manuscript book of drawings now known as Liber Bellicorum Instrumentorum, depicts a machine for communicating ideas or information through spectacle. The manuscript is fairly well known, and this sketch is just one of many interesting images worthy of study in its seventy leaves. About two dozen manuscripts of the mechanical arts from this period survive, the best studied of which fall into the “Sienese school” and the “German school” Fontana falls outside these, for he had far less influence than the Sienese. His work also is too early, it seems, to count in narratives directed toward the flowering of technological illustration in the sixteenth century. Of his images of subjects other than hydraulic and military machines only one deep study has been made, concerning two of the automata, although the present sketch has lately attracted a glance or two. Historians of technology pay scant attention to the first half of the fifteenth century, five decades that seem merely to repeat medieval knowledge and have the disadvantage to their prestige of falling “before Leonardo.” Whether one views Fontana as an engineer or as a science-fiction illustrator, a great deal in the manuscript has not been given its due. The brief, normative account in the literature so far on Fontana focuses on politics and warfare. My treatment of his castellus image in this article instead emphasizes issues of imagery, communication, subjectivity, moral feeling, spiritual life, and personhood. My account runs along two lines. For the first, I will suggest some untried ideas for approaching this image. In part this is in pursuit of what Jonathan Sawday calls the imaginative history of machines and mechanisms, though more largely it concerns contributing to a broad-range history of communication and persuasion. If we look at the image from our standpoint in a world accustomed to the reproduction of images, we readily see in it an early step toward our present control of the display and diffusion of images. Fontana’s castle of shadows (castellus umbrarum), based on a worldwide transfer of technical knowledge about imagery in antiquity (and even in prehistory), presents some of the continuing questions driving the reproduction of imagery and the dispersal of information. As a practical matter, a sense of proximity to Fontana and his time, as opposed to a sense of untranslatable distance, helps to broaden the historiography.
