Ceffyl Dŵr and the vow of silence for its riders
By Ralf Ittermann · last reviewed on
Ceffyl Dwr is a demon of Celtic (Welsh) tradition.
Deadly in North Wales, often helpful and warning in South Wales. The tradition binds its riders to a vow of silence, its nature shifting between menace and warning depending on the region.
The Ceffyl Dŵr is the water horse of the Welsh mountains: it lures tired travellers, carries them into the air and lets them fall, or drags them into the water.
Regionally divided: in North Wales sinister, in South Wales often a shining horse that warns and leads safely.
