This article deals with Calchas’ prophecy and Diomedes’ and Ulysses’ interventions during the mustering of the Greeks at Aulis in Statius’ Achilleid (1.514–52). It will be argued that Calchas and Ulysses embody two different approaches to the generic tensions of the new epic which Statius’ poem represents. Calchas, the old uates of the Homeric tradition, seems unable to fully understand the ‘poetics of illusion’ enacted by Thetis and Achilles in disguise, as is clear from his vision. His point of view is skilfully complemented by Ulysses, who turns out to be the true uates, as well as the perfect leader for Achilles’ rescue. As the only figure who can face the fluid and ambiguous reality of the poem and its literary dynamics as well, Ulysses also stands as a poetic voice himself; through his speech, Statius reflects upon the tensions of his epic and the poetic effort needed to channel the narrative from the peaceful setting of Scyros to the martial horizon of Troy.
