I have put this into a more narrative, story-driven format while preserving the historical and literary points.
Among the stranger episodes in ancient literature is the story of Lucius, a wealthy young aristocrat whose curiosity about magic goes terribly wrong. In both the Greek novel Loukios, or the Ass and the Latin masterpiece The Golden Ass (also called Metamorphoses) by Apuleius, Lucius is accidentally transformed into a donkey. Unable to reveal his true identity, he is stolen, beaten, bought, and sold from one master to another, forced to witness the hidden lives of the people around him.
One of his most memorable owners is a wandering group of priests devoted to the Syrian Goddess. Ancient Greek and Roman writers often associated these priests with the followers of Cybele, the Great Mother Goddess. Their rituals were famous for ecstatic music, wild dancing, colorful clothing, and religious ceremonies that challenged conventional ideas about gender and social roles. Classical authors also connected them with practices such as ritual self-castration and forms of sexuality that many Romans considered shocking or threatening.
Lucius, telling the story from his own perspective, describes these priests using the insulting word cinaedi, a common Greek and Roman slur for people viewed as sexually or gender nonconforming. Yet an interesting contrast appears in the novels. The priests never use this label for themselves. Instead, they refer to themselves as "girls" and consistently speak about themselves using feminine language and grammatical forms.
This difference in language reveals an important tension within the story. Lucius, representing the values of the wider Greco-Roman world, attempts to define the priests according to society's prejudices. The priests, however, present themselves in their own words and according to their own identities. The conflict is not simply about religion or appearance but about who has the authority to decide what another person is called and how that person is understood.
Modern scholars have pointed to these passages as evidence that at least some of the galli—the priests of Cybele and the Syrian Goddess—may have understood themselves in ways that do not fit simple male-female categories. Their own speech suggests identities that ancient society often marginalized but that they themselves openly embraced within their religious communities.
The story survives in two different forms. Apuleius' The Golden Ass is much longer and ends with Lucius finding salvation through the goddess Isis, while the Greek Loukios, or the Ass tells a shorter version of the adventure. Despite their differences, both novels follow the same basic plot of a man transformed into a donkey who wanders through the hidden corners of society before finally regaining his human form.
Because of the remarkable similarities between the Greek and Latin versions, many scholars believe they were both based on an even older work, a now-lost Greek novel called Metamorphoseis, traditionally attributed to Lucius of Patrae. Although that original story has disappeared, its influence survives through these extraordinary tales of magic, transformation, and the struggle over who has the power to define identity.
