The theory of the written sign in the commentaries of the Parisian Scotist theologian Peter Tartaret (fL 1485-1522) is inspired by Duns Scotus's commentaries on Aristotle's Peri Hermeneias. Tartaret differs, however, from Scotus in that his theory refers less to written sign understood within a causalist relationship with the significatum of the vox itself, than to a scriptum completely dependent on an equivalence between itself and the vox, of which it is a " synonym". Far from naturalizing the scriptum through notions of "similitude" and "proportion", Tartaret's recognition of its particular status within the semiotic triad confirms, on the contrary, the necessary and voluntary relationship that ties the written sign to the concept.
