The Hellenistic tradition bifurcated early in its codification, one track following Dorotheus and the other his younger contemporary, Ptolemy. The key drivers of the split are many, but they converge in a single issue: whether to reverse the Lot of Fortune for nocturnal charts. In close examination of what is said about lot theory, from Manilius to Dorotheus, from Ptolemy to Valens, we will outline why the choice you make regarding Fortune does matter, perhaps in ways you hadn’t considered. Wade Caves explores the origins of the Lot of Fortune, showing how misread ancient arithmetic gave rise to the doctrine of reversal – and how returning to the rationale of Nechepso and Petosiris restores Fortuna as the lunar counterpart to the solar ascendant.
