Gallus

Gallus or Galla (plural galli or gallae) is an Ancient Hellenist, Phrygian, and Roman religiogender for castrated priests (eunoukhoi) of the goddess Cybele (Magna Mater in Rome, sometimes Rhea in Greece). In modern times a gallus may be transfeminine, transsex, an androgynon, intersex, or an AMAB transgender person.

Priestesses of Cybele
The Gallae were priestesses of the Phrygian goddess Cybele and her lover, Attis, from about 2,300 years ago to 600 CE. According to mythology, Attis castrated himself beneath a tree in a fit of madness, dying of the wound; the reason for his insanity varies, but is usually a curse.

The gallae would castrate themselves in an ecstatic ritual as a devotional act to Cybele, casting their severed genitals into a home or crowd. Whichever family caught the genitals would then provide dress and care for the galla as they recovered from their emasculation. Afterwards, they would serve as a priestess to Cybele and Attis. It is of note that becoming a galla was not a requirement to serve as a priest to Cybele, implying that castration was indeed a form of sex reassignment to validate internal identity.

The Femminiello
It is believed that the galla tradition was continued by the Italian femminiello after the gallae were outlawed, destroyed, and/or integrated by the rise of Christianity.

Modern Gallae
In modern times, a number of individuals--mainly transgender women--may identify as gallae. Of note is the women's shelter and modern temple of Cybele in New York of worshipers calling themselves gallae established in 1998. Tales of the Galli is a historical fiction comic by a modern Galla by the name of Laura Seabrook chronicling the role, humanity, and life of the gallae.
