Matthew Francis Rarey’s essay ​”Camera Lucida Mexicana: Travel, Visual Technologies, and Contested Objectivities” discusses three nascent visual technologies—the camera lucida, the panorama, and the daguerreotype—as often stubborn and defiant agents in quests for both scientific rationality and picturesque image-making in the first four decades of the nineteenth century. It also details how the agency of such technologies emerged in the complex circuits of transatlantic intellectual and artistic exchange formed in order to represent, and thus claim access to or ownership of, Mexican history and archaeology across Europe and the Americas. This suggests the possibility of recasting the genesis of these technologies not as a fixed point, but as a process of transatlantic exchange oriented toward the New World and the south, in this case, Mexico. The essay is part of Visuality’s Romantic Genealogies, a special issues of Romantic Circles Praxis Series edited by Jill H. Casid and Theresa M. Kelley of UW-Madison, and featuring contributions by noted scholars Marcus Wood, Sophie Thomas, Kay Dian Kriz, and Lucy Traverse.
