This article discusses the terms in which Cicero, Lucretius and Diogenes Laertius sought to make sense of the prólêpsis of Epicurus. To give voice to and to divulge among Latin speakers the doctrine of Epicureanism, Cicero furnished the terms antecipatio, praenotio, and informationem, and Lucretius provided notitia, exemplare, and vestiga. Diogenes Laertius presented the terms katalêpsis, dóxa, énnoia, and hypólêpsin, with which, he says, the Epicureans tried to explain the prólêpsis of Epicurus. The article also discusses the views of some contemporary commentators.
