This paper puts the emphasis on the so-called Vorproömium of the Aeneid, and proposes a formal analysis
and commentary which explores the intertextual weft of the four verses, in order to emphasize their nonauthenticity.
It then provides a hypothesis for dating of the false proem (as early as possible in an advanced
Tiberian age) and investigates the purposes that led the anonymous author, who will remain unknown, to
invent these four verses.
