Artistic Data and Network Analysis Figure 1. Aby Warburg’s Panel 45 with the color version of the images mapped over the black-and-white photographic reproductions. Peer-Reviewed Images as Data: Cultural Analytics and Aby Warburg’s Mnemosyne Stefka Hristova Abstract: In this paper, by extending the methodology of media archaeology to the praxis of Cultural Analytics/Media Visualization I ask how have we compared multitude of diverse images and what can we learn about the narratives that these comparisons allow? I turn to the work of Aby Warburg who attempted to organize close to two thousand images in his Mnemosyne Atlas. In comparing contemporary methods of image data visualization through cultural analytics method of remapping and the turn of the century methodology developed by Warburg under the working title of the “iconology of intervals,” I examine the shifts and continuities that have shaped informational aesthetics as well as data-driven narratives. Furthermore, in drawing parallels between contemporary Cultural Analytics/Media Visualization techniques, and Aby Warburg’s Atlas, I argue that contextual and image color data knowledge should continue to be important for digital art history. More specifically, I take the case study of Warburg’s Panel 45 in order to explore what we can learn through different visualization techniques about the role of color in the representation of violence and the promise of prosperous civil society. Keywords: images as data, Aby Warburg, Cultural Analytics, color, visualization, violence, reconciliation In their current state, the methods information about the artifact. In this of Cultural Analytics and Digital project, I take on a hybrid Digital Art Humanities provide two radically Historical methodology that combines different ways of interpreting images. Cultural Analytics as articulated by Cultural Analytics calls upon the Lev Manovich with Digital Humanities understanding of images as objects paradigms. I apply this method to with features, and more specifically as the case study of Aby Warburg’s image-data in and of themselves. The Mnemosyne Atlas from 1924, and potential of this computational method to Panel 45 more specifically. The to digital art history was presented twenty-four images in Panel 45, many in detail in Manovich’s essay “Data of which were created by the Italian Science and Digital Art History.”1 fresco painter Domenico Ghirlandaio, Digital Humanities methodologies on comprise the objects for this study. I the other hand rarely analyze images selected Panel 45 because it grapples per se. Instead, they tend to focus on with the relationship between color and the metadata: historical and cultural violence. Using Cultural Analytics, I Images as Data render Warburg’s images as color-data. an understanding of not only of I argue that this color-data, situated in the formal elements of the images, the theoretical framework provided but also of their cultural meaning.5 by Christopher Johnson’s 2013 Digital While his panels contained no textual Humanities project about Warburg descriptions, Warburg kept notes that titled Mnemosyne: Meandering through listed provisional titles as well as the Aby Warburg’s Atlas2 and in reference overarching theme of each panel. with traditional art historical texts about Domenico Ghirlandaio, speaks The black-and-white photographs of to the larger tropes of violence and civil artworks were pinned either directly to reconciliation.
