Nigrinus

But a good marksman, a Nigrinus, begins with a careful examination of the mark, in case it should be particularly soft,—or again too hard; for there are marks which will take no impression from an arrow. Satisfied on this point, he dips his shaft, not in the poisons of Scythia or Crete, but in a certain ointment of his own, which is sweet in flavour and gentle in operation; then, without more ado, he lets fly. The shaft speeds with well-judged swiftness, cleaves the mark right through, and remains lodged in it; and the drug works its way through every part. Thus it is that men hear his words with mingled joy and grief; and this was my own case, while the drug was gently diffusing itself through my soul. Hence I was moved to apostrophize him in the words of Homer: So aim; and thou shalt bring (to some) salvation. For as it is not every man that is maddened by the sound of the Phrygian flute, but only those who are inspired of Cybele, and by those strains are recalled to their frenzy,—so too not every man who hears the words of the philosophers will go away possessed, and stricken at heart, but only those in whose nature is something akin to philosophy.
