Whence, and whither, Catius? I have not time[ to converse with you], being desirous of impressing on my memory some new precepts; such as excel Pythagoras, and him that was accused by Anytus, and the learned Plato. I acknowledge my offense, since I have interrupted you at so unlucky a juncture: but grant me your pardon, good sir, I beseech you. If any thing should have slipped you now, you will presently recollect it: whether this talent of yours be of nature, or of art, you are amazing in both. Nay, but I was anxious, how I might retain all[ these precepts]; as being things of a delicate nature, and in a delicate style. Tell me the name of this man; and at the same time whether he is a Roman, or a foreigner? As I have them by heart, I will recite the precepts: the author shall be concealed.
