Archaeologists believe that the pre-Christian stone idols were intended as centerpieces for worship sites. A majority of the surviving examples were rediscovered near sacred wells, rivers or trees. On the British Isles especially, these locations were typically adapted by early Christians for churches and monasteries. Many of the Celtic era stone carvings are of human heads, sometimes with multiple faces or heads. The modern consensus, first articulated by the historian
Anne Ross, is that the Celts venerated the head as a "symbol of divinity" and believed it to be "the seat of the soul".
Classical Greek and
Roman sources mention that Celtic peoples practised
headhunting and used the severed heads of their enemies as
war trophies, and would, in the words of Ross, "tie them to the necks of their horses, bearing them home in triumph...the more severed heads a warrior possessed the greater was his reputation as a hero." There are numerous
Insular Celtic—(that is, Celts living in
Great Britain and Ireland) myths in which severed but living heads preside over feasts and/or speak prophecies. This has led to speculation as to the existence of a
Celtic head cult. File:Armagh St. Patrick's Cathedral of the Church of Ireland North Aisle “Tandragee Man“ 2019 09 09 (cropped).jpg|The horned and brutish
