Priesthoods
Ceres was served by several public priesthoods. Some were male; her senior priest, the flamen cerialis, also served Tellus and was usually plebeian by ancestry or adoption. Her public cult at the Ambarvalia, or "perambulation of fields" identified her with Dea Dia, and was led by the Arval Brethren ("The Brothers of the Fields"); rural versions of these rites were led as private cult by the heads of households. An inscription at Capua names a male sacerdos Cerialis mundalis, a priest dedicated to Ceres' rites of the mundus. The plebeian aediles had minor or occasional priestly functions at Ceres' Aventine Temple and were responsible for its management and financial affairs including collection of fines, the organisation of ludi Cerealia and probably the Cerealia itself. Their cure (care and jurisdiction) included, or came to include, the grain supply (annona) and later the plebeian grain doles (frumentationes), the organisation and management of public games in general, and the maintenance of Rome's streets and public buildings.
Otherwise, in Rome and throughout Italy, as at her ancient sanctuaries of Henna and Catena, Ceres' ritus graecus and her joint cult with Proserpina were invariably led by female sacerdotes, drawn from women of local and Roman elites: Cicero notes that once the new cult had been founded, its earliest priestesses "generally were either from Naples or Velia", cities allied or federated to Rome. Elsewhere, he describes Ceres' Sicilian priestesses as "older women respected for their noble birth and character". Celibacy may have been a condition of their office; sexual abstinence was, according to Ovid, required of those attending Ceres' major, nine-day festival. Her public priesthood was reserved to respectable matrons, be they married, divorced or widowed. The process of their selection and their relationship to Ceres' older, entirely male priesthood is unknown; but they far outnumbered her few male priests, and would have been highly respected and influential figures in their own communities.
