Cassius: Did Cicero say any thing?
Casca: Ay, he spoke Greek.
Cassius: To what effect?
Casca: Nay, an I tell you that, I'll ne'er look you i' the face again; but those that understood him smiled at one another and shook their heads; but, for mine own part, it was Greek to me.
Julius Caesar (1599) act 1, sc. 2, l. [288]
