Hag Stone
Also known as Adder stone, Holey stone, Witch stone, Glain neidr, Milpreve
Pick up a beach pebble with a hole worn right through it and you are holding one of Britain’s oldest folk charms, once hung by doors, beds and stable stalls for protection.
A hag stone is simply a stone with a natural hole through it. Such stones turn up on beaches and riverbeds all over Britain and Northern Europe, and for centuries people have threaded them on string and hung them up for protection. Few talismans are so humble, or so pleasant to find.
How the hole is made
Nature makes hag stones in several ways. Moving water can wear a hole as pebbles grind against one another in a hollow. In flint, the hole often marks a place where a softer inclusion, sometimes the remains of an ancient sponge, has weathered away. Along some coasts, rock-boring shellfish called drill neat tunnels into soft stone.
The shingle beaches of Dorset, Sussex and Kent are well known for them, and so are many other shores and riverbeds. Every one is different in shape, colour and size, which is a large part of the pleasure of looking.
Many names
The stone has gathered names as it travelled through folklore. In England it is a hag stone, holey stone, witch stone or holy stone. In Wales it was called glain neidr, roughly “adder’s jewel”, and in Cornwall milpreve. These snake names come from an old belief that such stones were made when many adders gathered together, often around Midsummer or May Eve.
The idea is old. In the first century CE, the Roman writer Pliny the Elder described a “serpent’s egg” said to be formed by a mass of snakes and prized by the Druids of Gaul. Whether that object resembled a hag stone is uncertain, but the Welsh and Cornish snake stories clearly belong to the same family of belief.
The word hag points to another belief. In English folk speech a hag could be the night spirit thought to sit on sleepers and bring bad dreams, or to ride horses through the dark hours, a belief known as . The stone with a hole was the answer to her.
What it was believed to do
Holed stones have been kept as protective charms for centuries. Their main uses were practical and domestic:
- Hung above a bed to keep away nightmares and give peaceful sleep
- Tied to the stable key or hung over stalls, so that horses would not be ridden by night and found tired in the morning
- Hung by the front door or in a window to guard the home
- Kept on fishing boats in some coastal communities
- Carried in a pocket or worn on a cord as a personal charm
Folklorists of the early twentieth century noticed that the stones were often strung on red ribbon or thread, the colour and the stone working together. Others recorded strings of several holed stones hung up as a single charm for a stable.
Looking through the hole
One of the loveliest beliefs is that if you look through the hole, you may see what is otherwise hidden: the fairy folk, or the truth behind a disguise. Children still play the game on the beach, holding a stone to one eye and seeing the world through a small round window.
The sea makes every hag stone, and no two are ever alike.
Great stones with holes
Larger holed stones played their part in local custom too. At Men-an-Tol in Cornwall, a ring-shaped prehistoric stone stands between two upright ones, and a good deal of folklore grew up around passing through it. In Orkney, couples once joined hands through the hole of the Odin Stone near Stenness to seal their promises, until the stone was destroyed in 1814.
Finding and keeping one
Tradition holds that a hag stone means most when you find it yourself, and many people simply keep an eye out on every beach walk. The best time is a falling tide after rough weather, when fresh shingle has been turned over and wet stones show their colours and their dark holes most clearly. Take only a small stone or two, leave cliffs and protected sites untouched, and check local rules, since collecting is restricted on some beaches.
Thread it on cord, string or red ribbon and hang it by the door, over the bed or on your keys. It needs no care beyond an occasional rinse in fresh water, and it can always go back to the sea one day. For other ways of looking after small treasures, see caring for your talisman.
The hag stone shares its quiet work with the Horseshoe over the door and, far to the south, the blue glass evil eye. It is one of the simplest objects among the talismans of Northern Europe, and one of the most widely kept for protection and a peaceful home.
