Quintus Roscius, a Roman actor, born at Lanuvium, so celebrated on the stage that every comedian of excellence and merit has received his name. His eyes were naturally distorted, and he always appeared on the stage with a mask, but the Romans obliged him to act his characters without, and they overlooked the deformities of his face, that they might the better hear his elegant pronunciation, and be delighted with the sweetness of his voice. He was accused on suspicion of dishonourable practices; but Cicero, who had been one of his pupils, undertook his defence, and cleared him of the malevolent aspersions of his enemies, in an elegant oration still extant. Roscius wrote a treatise, in which he compared with great success and much learning the profession of the orator with that of the comedian. He died about 60 years before Christ.
