Abstract. Today, the weight of works created in historical and biographical content is increasing in Uzbek literature. Most of these works depict the events of the historical period, the characters of the writers and poets who lived and created in that period, and their ways of life. For example, Oybek's "Navoiy", "Starry Nights" and "Avlodlar Dovani" by P. Kadirov, "Mohlaroyim" by M. Karim, "Ahmad Yassavi" and "Avaz" by S. Siyoyev can be included. In creating the image of the creator, their prototypes are a rich resource for the writer and a great responsibility, as well. First, all historical sources related to the chosen hero should be carefully studied. Secondly, the writer should sort the collected sources and create his own artistic interpretation. In fiction, the image of the same creator can be artistically interpreted by different writers. In this article, Uzbek enlightener poet, Avaz the son of Polvonniyoz (Otar) is described as a poet and person through the novel "Avaz" by Sa'dulla Siyoyev, and the historical events of that time are described.
