581 Josephus may have known this at first hand (he certainly wishes to convey this impression), and later extends an invitation to readers to consult the work themselves (1.182). If this is not an empty gesture, it suggests some confidence that he knew what it contained. If so, his peculiar truncation of the tale raises all the more suspicion (see note to “endurance” at 1.182). The topic of sleep interested philosophers as it suggested that the soul had a life separate from the body, and if separable, arguably immortal. On Clearchus’ inclination to the Platonic (and early Aristotelian) viewpoint on this subject, see Wehrli 1948: 47.
