Horse Skull Meaning: The Mari Lwyd, Hidden Floor Skulls and O'Keeffe's Desert

The best-known horse skull in Britain belongs to the Mari Lwyd, and it has its own full story on this site. In brief: Museum Wales describes the Mari Lwyd, meaning "Grey Mare," as a decorated horse skull carried from house to house during the Christmas season. The earliest known account dates to 1798, per Museum Wales, and the custom was especially active in Glamorgan, Monmouthshire and Carmarthenshire between about 1850 and 1920. The party sang at each door and traded improvised verses, the pwnco, with the people inside, and letting the Mari in was associated with good luck (Museum Wales).

The skull itself was a working piece of kit. Museum Wales notes that its jaw could be mounted on a spring so that it snapped shut, its eyes might be made from glass bottles, and the same skull could be preserved in lime and brought out again each December. A Mari, in other words, could last for years and keep its bite.

For the people who kept it, the meaning was the visit itself: a winter house call with song, wit and good luck for whoever opened the door.

Across the border in England, East Kent had a related but different custom. In the nineteenth century, farm workers carried a Hooden Horse from farm to farm around Christmas Eve. Its head was carved from wood and usually worked by a person hidden under sacking. Percy Maylam saw the custom in Thanet during the 1880s and published his study of it in 1909 (Kent Archaeological Society).

That wooden head matters. The Kent Archaeological Society account makes clear that the standard Kentish form used carved wood, not a real skull, and it treats claims of a very ancient origin with caution. So, the Hooden Horse belongs in a horse skull story as the horse-head custom without the bone. The shape and the seasonal visit, it turns out, can travel without the skull itself.

Some of the most surprising horse skulls are the ones nobody was meant to see. In Ireland, horse skulls were concealed beneath floorboards, under flagstones, beside hearths, beneath church altars and sometimes even in bridges. The Irish folklorist Seán Ó Súilleabháin reported the practice in 1945, including skulls with coins placed inside them (JSTOR Daily).

The most down-to-earth explanation is sound. Barry O'Reilly proposed that the hollow skull worked as a sound box, amplifying dancing feet during a céilidhe, an evening of music and dance. Irish informants, as JSTOR Daily reports, said the skulls gave a "fine hearty echo" and made the dancing sound better. The same idea reached the church: in County Wexford, reports described horse skulls beneath church altars so that the preacher could be heard throughout the building.

It is hard not to enjoy the thought of a whole kitchen of dancers stamping over a buried skull because it made the floor sing. For the people who laid them, that was a practical choice as much as anything mysterious.

There is a second reading, and it sits beside the first rather than replacing it. Some hidden horse skulls may have been foundation or protective deposits. Eamonn P. Kelly of the National Museum of Ireland recorded beliefs that horses could see ghosts and evil spirits (JSTOR Daily), which would make a horse's head a sensible guardian to place in a house.

Archaeologists have looked at the wider pattern. Maeve Sikora connected horse deposits in Norway, Iceland, Scotland and Ireland with fertility symbolism in Scandinavian mythology, while Colm Moriarty and Sonja Hukantaival discussed ritual deposits in buildings (IAC Archaeology). One concrete find gives the idea weight. At Haynestown in County Louth, archaeologists uncovered a disarticulated horse skull resting on a flat stone in a shallow pit, with charcoal, shells, horseshoes and a fish hook around it.

The evidence from Ireland, Britain and southern Scandinavia supports both the acoustic and the ritual readings. That means one hidden skull does not explain another. If you know of a horse skull found in an old house or church, its meaning is written in that building's own history and in the excavation report for that site and date.

Older still are the burials where horses went into the ground whole, the skull being only one part of the animal. Scythian burial mounds, or tumuli, built between the seventh and fourth centuries BCE across the eastern European steppe and the North Caucasus held horses buried with high-status people. The Encyclopaedia Iranica records complete horses with their harnesses, sometimes in large numbers linked to the status of the dead, and notes that the Greek historian Herodotus described royal Scythian funerals involving horses (Encyclopaedia Iranica). In 2024, Antiquity reported an early Scythian funerary site in eastern Eurasia where horse bones lay with animal-style objects and riding equipment (Antiquity).

In Viking Age Scandinavia, horse burial was a regional practice rather than a universal one. Anne Pedersen's 2021 study finds concentrations in Uppland and Västmanland in eastern Sweden, in southeast Norway and in parts of western Sweden (Anne Pedersen). Work on Viking Age Iceland shows horse burial there as a specific rite practised during a limited period (University of Iceland record).

These were people burying animals they had lived and ridden with, and the burials speak of status, riding culture, sacrifice and funeral ceremony. Each grave tells its own story by region and date; together they show how much horses mattered in life and in death.

In American art, the horse skull belongs above all to Georgia O'Keeffe. After visiting New Mexico in 1929, she gathered sun-bleached animal bones and used them as symbols of the desert. She painted horse, mule, deer and steer skulls, and the Whitney Museum describes her skulls and flowers as symbols of life and death within the natural world (Whitney Museum). The Met's record for *From the Faraway, Nearby* sets her bones in the same desert country (The Met).

Her *Horse's Skull with Pink Rose*, from 1931, is the one to know here. LACMA describes it as a modern vanitas, joining the skull's evocation of death and fleeting beauty with a rose (LACMA). That links it to the older painting tradition told in our story on vanitas paintings, and the rose pairing has its own history in skull and roses meaning. For her skull paintings in full, see O'Keeffe's skull paintings, and for the steer skull on the Southwest wall, see cow skull meaning.

A horse skull in this tradition can suggest desert survival, mortality, beauty, time and the land itself. It is not automatically a symbol of the whole American West, and it is not an Indigenous symbol unless a specific nation, artist or community is named.

Today, most horse skulls people meet are in tattoos and decor. Modern tattoo guides such as Tattoo Scribes describe a horse skull tattoo as joining the horse's associations of strength, freedom and independence with the skull's associations of mortality, change, resilience and the cycle of life. These are contemporary design readings, not historical meanings handed down from the customs above.

A horse skull tattoo can also be a memorial to a particular horse or a nod to family history, a love of Western or Gothic imagery, or simply a shape the wearer likes. What surrounds it changes the reading: flowers, desert plants, a bridle, weapons or a rider each push it in a different direction. The meaning that counts is the one the wearer gives it, so if you are admiring someone's ink, ask them. If you are planning your own, our story on skull tattoo meaning covers the wider design choices.

Short answers to the questions that come up most about horse skulls.

A horse skull tends to bring its place with it: a Welsh doorway at Christmas, an Irish kitchen full of dancers, a royal mound on the steppe, a New Mexico canvas. If you like reading an animal skull that way, the bison skull has a very different American story, and the ram skull and deer skull have their own. For O'Keeffe among other painters, try famous skull art, and for the wider story of what skulls have meant across the world, start with skull symbolism.
