#Christian theology of late antiquity promoted the idea of “primal androgyny,” that is, that human beings were created as androgynous beings (Adam before the separation of Eve) and that this non-binary state was the ideal state for humanity.
This concept fell from popularity around the 12-13th centuries, as androgyny became conflated with dual-bodied hermaphroditism and thus with monstrosity.
