Disputa de l’ase (1417) is a Catalan medieval novel. It is about the discussion between a monk and a donkey about the human superiority over the other animals. After a long debate, and completely by surprise, it is the donkey who wins the argument, and so human superiority cannot be proven. The work was written by Anselm Turmeda, a Majorcan writer and former Catholic friar who lived in Tunis and converted to Islam. It is his longest work in Catalan, his mother tongue. It is of Arabic inspiration, even though it incorporates an important portion of original elements, such as the literary style and a strong feeling of anti-clericalism.
