The Hill of Sorcery: Mythology and Archaeology of the Tlachtga Barrow
In an era long passed, all of the fires of Ireland were extinguished at sundown on October 31 st, and a single blazing bonfire was lit at the epicenter of the annual feast of the dead—Samhain had begun at the Hill of Ward. The Druidical priests gathered the people together, and set places with food offerings for those unseen, which had crossed into the realm of shadow, the land of the dead. For between the nights of October 31 st and the 1 st of November, the barriers between the worlds, which closed the doors of perception throughout the year, would fall away and the dimensions would interact freely with one another. At this time when the harvest faded and the darker time of winter began, the known and the unknown would meet, and dance in the flickering light of the celebratory flames.

It was not only the dead, but also the powerful aos sí who would cross into the land of the living on Samhain. The aos sí were a supernatural race, which according to the Lebor Gabála dwelt in an alternate world existing side by side with our own, usually imperceptible to mortals. They are variously considered archetypal deified ancestors or gods and goddesses, associated by some with the Tuatha Dé Danann, who legend states disappeared into the Celtic Otherworld. The Otherworld ( Tír nAill , “the other land”) was entered by way of ancient burial mounds or caves. In fact, one translation of aos sí is people of the mounds. Along with the aos sî, it was also believed that the souls of dead family and friends were attending their former homes and the festivities, and many left food, drink, and special treats out for the dead. Rituals, disguises, and the reciting of verses were commonplace, and seasonal foods such as nuts and apples were also incorporated into the celebrations.
The Hill of Ward, located 2 km (1.2 miles) east of Athboy in the county of Meath, is host to one of the most fascinating archaeological sites in the world: the Tlachtga Earthworks (pronounced “Clackda”).

The monument still visible today is a circular earthwork consisting of four concentric ditches with earthen banks, with an outer circumference of 150 m (492 ft.) in diameter. Quadrivallate hengiform earthworks are considered to be extremely high status, and a similar example—known as the Rath of the Synods—is located at the nearby Hill of Tara.

“Tlachtga” is thought to mean “earth sphere”, and as the site of the Samhain fires, the ring work has attracted numerous legends over the centuries. One such legend involves a powerful magician named Mug Ruith, and his daughter Tlachtga (presumably after whom the site was named). Apparently, the two had traveled to Rome to study under the discipleship of the Gnostic sage Simon Magus. Some versions of the story have it that Simon took Mug Ruith to a secret place where he revealed the secrets of the sacred Isles over the course of either 6 or 33 years. Eventually, the trio designed a mysterious flying device known as the Roth Ramach , in which they sailed across the heavens. The flying device apparently had the power to blind all that gazed upon it and to kill those brave enough to touch it, and Tlachtga herself is said to have buried it at the site of the Hill of Ward. Some versions of the legend have it that Tlachtga was raped by Simon’s sons, while others say that she actually bore him three sons; Dorb, Cuma, and Muach, dying in childbirth at the enclosure which bears her name. This is probably an indicator of Tlachtga’s earlier status as a mother goddess who may have been worshipped at the site. The Tlachtga barrow never lost its relevance in the minds of the Irish people. For example, in 1167, High King Ruaidrí Ua Conchobair chose the site for a great reform synod attended by all of the provincial kings, ecclesiastical figures, and 13,000 horsemen.

Excavations at the Tlachtga Barrow have revealed that the site was used for millennia, yielding evidence that certainly fires the imagination. There are actually three enclosures now recognized at the site, two of which are no longer visible. Research conducted in 2014 at the visible monument revealed one of the banks to be constructed of layers of small and medium sized stones and sand. A fox tooth recovered from one of the ditches was radiocarbon dated to the 5 th century AD. In the outer ditch, worked chert and a fragment of a megalithic sandstone featuring four parallel grooves were found. The visible enclosure was actually constructed over a more ancient earthwork consisting of three concentric banks, 195 m (639 ft.) in outer diameter. The inner ditch of this enclosure was 0.75-0.85 m (2-2 ft.) wide at the base, expanding to 3.4 m (11ft.) wide at the top. In the strata of fill representing the final phase of the ditch, a cattle bone was found and radiocarbon dated to the 4 th century BC. Articles associated with the earlier enclosure include a bone pin, clay pipe stem, metal disk, chert and worked flint.
