This article attempts to elucidate the description of Ovid’s ingenium by Seneca the Elder (Contr. 2.2.8) through an inquiry into its rhetorical and poetic models, namely Ovid himself and Horace. Aspects of literary allusiveness in Seneca are therewith explored, as well as possible links, both literary and prosopograhical, between Horace’s Epistles and Ovid. Finally, an examination of Horatian influence on Seneca’s portrait of Ovid and on Ovid’s self-portrait as an exiled poet proves relevant to the question about the date of Horace’s Ars Poetica.El presente trabajo intenta elucidar la descripción del ingenium de Ovidio por Séneca el Viejo (Contr. 2.2.8), indagando en sus modelos retóricos y poéticos, principalmente Ovidio mismo y Horacio. La tarea permite explorar cuestiones de alusividad literaria en Séneca, y posibles conexiones, prosopograficas y literarias, de las Epístolas horacianas con Ovidio; asimismo, abordar la influencia de Horacio en Séneca y en el autorretrato del Ovidio exiliado es de interés para la cuestión sobre la fecha del Ars Poetica
