This article asks what part prehistory could play in establishing a posthumanist settlement, alternative to the humanism of the Enlightenment. We begin by showing how Enlightenment thinking split the concept of the human in two, into species and condition, establishing a point of origin where the history of civilization rises from its baseline in evolution. Drawing on the thinking of the thirteenth-century mystic, Ramon Llull, we present an alternative vision of human becoming according to which life carries on through a process of continuous birth, wherein even death and burial hold the promise of renewal. In prehistory, this vision is exemplified in the work of André Leroi-Gourhan, in his exploration of the relation between voice and hand, and of graphism as a precursor to writing. We conclude that the idea of graphism holds the key to a prehistory that not so much precedes as subtends the historic.
