One who castrates; a person (historically often a specialized practitioner) who performs castration on animals or humans.
From Latin 'castrare' (to castrate) with the agent suffix '-or', parallel to 'castrater' but using the Latin-derived agent noun form.
Medieval castrators were so skilled at their craft that they developed specialized instruments and techniques still studied by historians—some achieved such fame that they traveled between kingdoms performing the procedure.
