 The lines are quoted by Sextus Empiricus (M 11.20); there is no further trace of them in the surviving record. The context in which Sextus introduces them shows that he is inclined to understand the first couplet according to reading (A) rather than reading( B); but he suggests that he is not sure about this. The speaker into whose mouth Timon put these lines is never identified, but it has generally been assumed to be Pyrrho.
