 Here again we encounter Xenocrates the theologian: Sextus tells us (149) that Xenocrates associated the three fates with his three groups of substances: Atropos with the intelligible ones, Clotho with the perceptible ones, and Lachesis with the believable ones. This sounds a Xenocratean touch: it connects with the interpretation of Plato (see Republic X 620d–e) and takes mythology very seriously.
