was consul A. D. 68 with Silius Italicus, and a relation of Galeria Fundana, the wife of Vitellius, who protected him on the accession of her husband to the throne. Trachalus is frequently mentioned by his contemporary Quintilian, as one of the most distinguished orators of his age. Tacitus takes notice of a report that Trachalus wrote the orations which the emperor Otho delivered, but the speeches of Otho in the Histories of Tacitus (1.37, 83) were composed by the historian and not by Trachalus.
