Understanding contemporary environments in the laboratory and elsewhere requires grappling conceptually with multiple, coexisting, nonconforming infrastructures which actors engage at the same time. In this article, I develop the analytical vocabulary of “seams” for studying heterogeneous, multi-infrastructural environments. Drawing upon six years of ethnographic fieldwork with two distributed science teams, as well as studies in Ubiquitous Computing, I examine overlaps among infrastructures and how actors work creatively with and across their seams. Rather than suggesting that actors are hemmed in or (...) incapacitated by multiple infrastructural commitments, inclusions, and exclusions, I show instead how they work artfully to align them in ways concordant with membership and how this produces both consequences for their work and opportunities for analysis.

This article investigates the maps of the moon produced in the mid-seventeenth century by Jesuit Giambattista Riccioli and Johannes Hevelius, whose cartographic projects competed for widespread acceptance. Although Hevelius’s Selenographia was applauded for its many detailed, self-engraved pictures of the moon, his cartography and proposed nomenclature were supplanted by Riccioli’s as offered in Almagestum novum, in spite of the latter’s simplistic pictures and promotion of geocentric cosmology. Exploring this paradox through pictorial analysis, three types of images common to both Selenographia (...) and Almagestum novum are compared, employing an analytical tool developed by Svetlana Alpers in The art of describing. A focus on this debate exposes the tensions evoked by new technologies of vision and competing cultures of visual epistemology in seventeenth-century astronomy. As both selenographers grappled with questions about the role of representation and what kinds of knowledge could be generated visually, the successes and failures of their competing projects present implications for the course of visual astronomy, as well as for our understanding of the use of ‘visual technologies’ in a period of controversy.Keywords: Johannes Hevelius; Giambattista Riccioli ; Svetlana Alpers; Astronomy; Early modern; Moon maps; Visual culture; Images in science.
