AFER, DOMITIUS, a Roman orator and advocate, was born at Nemausus (Nimes). He became an informer and gained the favour of Tiberius by accusing Claudia Pulcra, a cousin of Agrippina, of treason. He was consul under Caligula (39) and superintendent of the water supply under Nero. He died in A.D. 6o. His pupil, Quintilian, who calls him the greatest orator he had ever known, quotes some of his witty sayings (dicta), collections of which were published, and mentions two books by him On Witnesses.
