The Galli were eunuch priests of the goddess Cybele, whose cult spread all over the ancient world from Mesopotamia to Rome.   They were famous for their extravagant clothes and feminine appearance. 

The galli castrated themselves during an ecstatic celebration called the Dies sanguinis, or "Day of Blood", which took place on March 24. On this day of mourning for Attis, they ran around wildly and disheveled. They performed dances to the music of pipes and tambourines, and, in an ecstasy, flogged themselves until they bled. This was followed by a day of feasting and rest.

The signs of their office have been described as a type of crown, possibly a laurel wreath, as well as a golden bracelet known as the occabus. They generally wore women's clothing (often yellow), and a turban, pendants, and earrings. They bleached their hair and wore it long, and they wore heavy makeup. They wandered around with followers, begging for charity, in return for which they were prepared to tell fortunes.

In Rome, the head of the galli was known as the archigallus, at least from the period of Claudius on. A number of archaeological finds depict the archigallus wearing luxurious and extravagant costumes.

In Rome, the Galli and their cult fell under the supreme authority of the pontifices, who were usually drawn from Rome's highest ranking, wealthiest citizens. The Galli themselves, although imported to serve the day-to-day workings of their goddess's cult on Rome's behalf, represented an inversion of Roman priestly traditions in which senior priests were citizens, expected to raise families, and personally responsible for the running costs of their temples, assistants, cults, and festivals. As eunuchs, incapable of reproduction, the Galli were forbidden Roman citizenship and rights of inheritance; like their eastern counterparts, they were technically mendicants whose living depended on the pious generosity of others. For a few days of the year, during the Megalesia, Cybele's laws allowed them to leave their quarters, located within the goddess' temple complex, and roam the streets to beg for money. They were outsiders, marked out as Galli by their regalia, and their notoriously effeminate dress and demeanour, but as priests of a state cult, they were sacred and inviolate. From the start, they were objects of Roman fascination, scorn, and religious awe. No Roman, not even a slave, could castrate himself "in honour of the Goddess" without penalty; in 101 BC, a slave who had done so was exiled. Augustus selected priests from among his own freedmen to supervise Magna Mater's cult, and brought it under Imperial control. Claudius introduced the senior priestly office of Archigallus, who was not a eunuch and held full Roman citizenship.

The religiously lawful circumstances for a Gallus's self-castration remain unclear; some may have performed the operation on the Dies Sanguinis ("Day of Blood") in Cybele and Attis' March festival. Pliny describes the procedure as relatively safe, but it is not known at what stage in their career the Galli performed it, or exactly what was removed, or even whether all Galli performed it. Some Galli devoted themselves to their goddess for most of their lives, maintained relationships with relatives and partners throughout, and eventually retired from service. Galli remained a presence in Roman cities well into the Empire's Christian era. Some decades after Christianity became the sole Imperial religion, St. Augustine saw Galli "parading through the squares and streets of Carthage, with oiled hair and powdered faces, languid limbs and feminine gait, demanding even from the tradespeople the means of continuing to live in disgrace".

They were infamous, derided, and tightly controlled as well. The holiness, or apartness, of priesthoods wasn't for the priest but for the commonwealth. A theme throughout Roman history, because these nasty creatures in all cults could stir up frenzy in the crowds.
