Los versos pitagóricos de Clara Janés

The late work of the Spanish poetess Clara Janés is characterized by the reception of mathematics. The present article analyses this particular characteristic focusing on the question how the concept of number unfolds itself in the poems. On the basis of a brief reflection on the relation between poetry and mathematics from a general point of view, the author presents a double lecture, cosmological and mystical, of Janés' work, concluding that she follows the Pythagorean tradition and "poetizises" mathematics in order to indicate the ineffable mystery of creation which is, in the end, also the mystery of poetry itself.
