This article tests a comparative and trans-disciplinary methodology I am developing for a research project titled ‘Un-Walling the Mediterranean Sea. New Southern performances: towards a no-border wall poetics and politics of togetherness’. The article investigates ways to develop and make visible MediterrAtlantic theories and performances inspired by grass-roots activism and artivism in order to disrupt Eurocentric geopolitical cartography. To this end, I will make reference to many (de)signs disseminated by trans-Mediterranean intellectuals, activists, artists, migrants and refugees along the Mediterranean routes and walls, as a way to shape both an Asian-African-European Mediterranean consciousness and a new TransMediterrAtlantic one. Finally, I will use as a case study Io sto con la Sposa, a docufiction on the experience of asylum seeking in Europe, by Antonio Augugliaro, Gabriele del Grande and Khaled Soliman (2014).
