Converso poet Antón de Montoro creates a material poetics based on a subtle positioning that reveals his contact with urban oligarchies, a middle class of artisans and merchants, and courtly bureaucrats. Through an intense poetic activity, Montoro negotiates his converso identity and middle status with several interlocutors that return to him a stigmatized image that disqualifies him for poetic practice. The result is an affirmation of the self as social being that sustains and justifies the material quality of poetry.
