Finished on November 2008, this article is devoted to Ibn Manẓūr's Aḫbār Abī Nuwās and to the methods according to which it shaped the famous muḥdaṯ poet into a complex literary image. For this purpose, I shall first consider the relations of Ibn Manẓūr's book to the homonymous work of Abū Hiffān al-Mihzamī and to the monumental Kitāb al-Aġānī. Then, I'll point out the shifts by which the man al-Ḥasan Ibn Hāni' turned into a legendary hero and became the parangon of brilliant libertine poet. For that purpose, I'll go through the following themes : The poet's identity, his familial ties, his relations with the Abbassid caliphs and with women. At last some trails to explore will be signalled and two particularly original narratives told by Ibn Manẓūr shortly presented.
