Celer and Nepos

Asconius 63, commenting on the pro Cornelio: Fuerunt enim plures Quinti Metelli, ex quibus duo consulares, Pius et Creticus, de quibus apparet eum non dicere, duo autem adulescentes, Nepos et Celer, ex quibus nunc Nepotem significat. Eius enim patrem Q.Metellum Nepotem, Baliarici filium, Macedonici nepotem qui consul fuit cum T. Didio, Curio is de quo loquitur accusavit … Cicero and his scholiast refer to ‘duo Metelli, Celer et Nepos’ but like Asconius do not specify their relationship. Celer himself, followed by Cicero in correspondence with him, calls Nepos his frater, but since both bore the praenomen Q., this cannot be the whole story. Celer's career shows that he was the elder, yet Nepos senior, according to Asconius, entrusted his feud with Curio not to him but to Nepos iunior.
