eunuchism

Political eunuchism became a fully established institution among the Achamenide Persians.

When the cult of Cybele was imported to Rome at the end of the 3rd century BC, its traditional eunuchism was confined to foreign priests (the Galli), while Roman citizens formed sodalities to perform honors in keeping with their own customs.

When the cult of Cybele was imported to Rome, the eunuchism of her priests the galli discouraged Roman men from forming an official priesthood; instead, they joined sodalitates to hold banquets and other forms of traditional Roman cultus in her honor.
