The Greeks created a culture that seemed secure and well ordered, in which status, gender and identity appeared to be if not fixed, then at least clear cut. A free man knew his place and his privileges, a foreigner was aware of their disabilities, an enslaved woman had a fair idea of her lot, a worker in the mines of Laureion even more so. Yet, lived experience was precarious. The rich man could lose his fortune, the highborn girl could become shipwrecked and enslaved. These are not just the plot devices of Hellenistic novels; they are the potential experiences of men and women for whom vulnerability and impermanence were as real as wealth and good fortune. These conditions favoured expressions – stories and images in particular – that made change and anomaly part of the cultural repertoire of the Greeks. This is perhaps why the vivid, vibrant hybrids of the Greek imagination attracted so much attention from Christian writers. By imagining other ways of engaging with the world and offering alternatives to the settled convention, hybrids would always be a threat to those attempting to impose their order. Hybrids became demons to be slain.
