Manlius, upon this, takes the tribune aside, and presenting a poniard to his breast, “Swear,” says he, “that you will let this cause fall, or you shall have this dagger in the heart of you; and now it is at your choice which way you will deliver my father.” The tribune swore and kept his word, and made a fair report of the whole matter to the council. He that makes himself famous by his eloquence, justice, or arms, illustrates his extraction, let it be never so mean; and gives inestimable reputation to his parents. We should never have heard of Sophroniscus, but for his son Socrates; nor for Aristo and Gryllus, if it had not been for Xenophon and Plato.
