The present Master s dissertation has two central concepts as object of investigation that support a discussion about the poetry and rhapsody exposed by Plato in his early dialogue, Ion: the concept of techne, a pattern of comparison which the philosopher uses to demonstrate that it is not through art/ability that the poet and the rhapsodist turn out to be capable of talking about different subjects; and the concept of poetical inspiration, which disrupts in part the traditional concepts of poetry at the time, as it sustains the possibility of straight connection with the Muses, a possibility which can stop man´s rational faculties temporarily. From the intertwine of these two ideas, traits emerge concerning the redirection of the rhapsodic activity and the new understanding about poetry, whose presence in his following dialogues attests its programmatic nature and points to the origin of Philosophy.
