a Roman rhetorician, who earned an infamous character by undertaking prosecutions to please the early emperors. He is first mentioned at the commencement of the reign of Tiberius, when he supported the accusation of Caepio Crispinus against Granius Marcellus. In A. D. 62, he accused Seneca as one of the associates of C. Piso, but the accusation was retorted upon him by Seneca (Tac. Ann. 1.74, 16.17). Romanus Hispo constantly occurs as one of the declaimers in the Controversiae of the elder Seneca.
