Whereas so much of the terminology of medieval history and criticism is the invention of the eighteenth century, the terminology of troubadour poetry is wholly contemporary. The worldly, witty, and self-conscious verse was discussed and evaluated by its practitioners and their circles. Poets wrote verses criticizing and satirizing each other and theorizing about their own poetry. Literary controversy developed, with songs exchanged like challenges. Should poetry be clear and accessible, easy to understand, and social in nature (trobar leu), as in the verses of Bernart de Ventadorn and Raimon de Miraval, or should it be personal, allusive, and difficult, making use of colored words with overtones and nuances, like the poetry of Arnaut Daniel (trobar clus)? Macabru boasted that he had written poems he himself could not understand.
