Noirons li Arabis is one of the many unica that punctuate the ms. L.11.14 of the National University Library of Turin, damaged by the fire of 1904. The present contribution provides a new study on this narrative unit, now almost illegible to the naked eye apart from a few sections having survived the flames. My examination takes as its point of departure a re-establishment of the critical text largely based on the editions published before the fire and focuses on the figure of Virgil and his fictitious genealogy, while situating this narrative unit within the general structure of the manuscript.
