One of the defining features of modernism lies in its far-reaching rethinking of the relation between the human and the non-human. In the present volume, this crucial aspect of modernism's legacy is investigated from an authentically transnational perspective, taking an innovative stance on a diverse range of authors - from posthumanist classics such as Beckett and Woolf to Valentine de Saint-Point, Radoje Domanovic and Aldo Palazzeschi among others. On the one hand, this collection sheds new light on the modernist contribution to posthumanism, providing a valuable reference point for future studies on the topic. On the other, it offers a new take on the transnational dimension of modernism, highlighting unexplored convergences between modernist authors from several different national contexts.
