Fundamentally, this paper is an intervention on the crucial importance of the geophysical when situating and defining the space of the Maghrib.1 Considering the age-old question, “Where is the Maghrib?,” to borrow the title of an introduction to a recent special issue of Arab Studies Journal, requires attending to the Maghrib’s unique liminality, its “interstitial position between different continents and transnational cultural formations, a variety of linguistic, ethnic, racial, religious, aesthetic, and other cultural elements [that] constitute the Maghrib. This position as a space-between-spaces makes the Maghrib a hub for human hybridization, literary creolization, artistic miscegenation, and cultural cross-pollination.”2 Although these cultural and identity-based narratives are crucial, I argue that framing the Maghrib’s liminality in terms of “space-between-spaces” concurrently requires accounting for the region’s geophysical dimension—its topography, morphology, volume, geological density, and material agency, among other markers.
