This study aims to introduce the term (aesthetics of ugliness), and the poet Badr Shaker Al-Sayyab, the pioneer and founder of Tafil poetry, was chosen, because his poetry collection is filled with the theme of ugliness and its movement between image, myth, place, and others. The reason for his collection of ugliness is due to the social and economic conditions, as well as the political conditions from which the poet truly suffered until he passed away far from his family and homeland. Ugliness - as is known - is the opposite of beauty. Hence, the study chose the term aesthetics despite its dissonance and contradiction, in an effort to create an ontology specific to it. The question then arises: How can ugliness have beauty? Are there aesthetics to ugliness? This is what the study will seek to answer by revealing it through the determinants that dominated the poets style. Hence, the study presented ugliness in terms and importance. To demonstrate his specificity and presence in the cultural and humanitarian scene, to determine his effectiveness and process in literature in general and in the poets experience in particular.
