Introduction: When Celtic Tradition Meets Ancient Greece
Halloween, the festival of pumpkins, costumes, and "Trick or Treat," is inextricably linked in the minds of most with Ireland, the Celts, and American lifestyle. Its official history traces its roots back to the ancient Celtic festival of Samhain, which marked the end of the harvest, the beginning of the dark winter, and the "blurring" of the lines between the world of the living and the dead.
However, a deeper look into Europe's ancient rituals reveals a striking affinity with Ancient Greek customs, specifically the Anthesteria. Many scholars now argue that Samhain, and by extension modern Halloween, carries a hidden "Greek DNA," which reached the Celtic West through ancient trade and cultural exchanges. By examining the similarities in themes such as the souls of the dead, disguises, and the warding off of evil spirits, we discover a common pagan core connecting Dionysus with the Celtic deities.
The Celtic Origin: Samhain and the Bridge of Worlds
Samhain was celebrated on the eve of November 1st by the Celts (who inhabited areas such as modern-day Ireland, Scotland, and Great Britain), marking the transition from the bright half of the year to the dark one. The Celts believed that on this night, the Veil between the world of the living and the Otherworld became extremely thin, allowing the dead and spirits to return to Earth.
To appease or frighten these spirits, people lit large sacred bonfires and wore terrifying costumes, often made from animal skins, attempting either to mimic the spirits so as not to be recognized or to scare them away. The custom of offering treats and food provisions (which later evolved into "Trick or Treat") was initially a way to ensure the good will of the spirits or the costumed mortals who represented them.
The Anthesteria: The Ancient Greek Festival of Souls and Dionysus
In Ancient Athens, the festival of the Anthesteria, which took place in late February, presents astonishing structural similarities to Samhain. The Anthesteria was a three-day celebration honoring Dionysus, the god of wine, vegetation, but also the Underworld. It was also the official day when the dead were permitted to wander the Earth, just as they did during Samhain.
The Arrival of the Dead
The second day of the Anthesteria, the Choes (or Khoai), was dedicated to consuming the new wine (hence the association with the Dionysia) and was considered the day when the gates of Hades opened and the souls (the Keres) ascended to Earth. The Ancient Greeks closed the temples, chewed on rhampnis a plant with repellent properties, and smeared pitch (or vines) on their doors to protect themselves from malevolent souls, while no one ventured outside after sunset. The use of repellent substances and isolation mirrors the bonfires and attire of the Celts.
The Disguises and the Prank
During the Anthesteria, primarily on the second day, people dressed up (usually as followers of Dionysus, such as Satyrs and Nymphs) and visited friends, exchanging jokes and perhaps playing minor "pranks" (similar to the trick) on the occasion of the temporary reversal of order permitted by the festival. The link between disguise and contact with or repulsion of dead spirits is a strong common element connecting the disguised followers of Dionysus with the masked figures of Samhain.
The "Keres Out, Anthesteria Done"
The third day, the Chytroi, was dedicated to Hermes Psychopomp. The day concluded with a ritualistic phrase shouted by the Athenians, closing the festival: "Thyrwzate Keres, ouketi Anthesteria!" ("Out, Keres [spirits], the Anthesteria is over!"). This phrase, which served as a ritualistic banishment of the dead back to Hades, is functionally identical to the warding off of evil spirits during Samhain/Halloween.

Cultural Interconnection: How the Greek Touched the Celtic
The theory of the "Greek DNA" in Halloween is not based solely on ritualistic similarities. The Greeks of Phocaea had established colonies such as Massalia (600 BCE) in Southern Gaul. Contacts between Greeks and Celts, through trade, religion, and cultural exchanges, were continuous.
It is highly probable that the ancient Celts, having come into contact with the rituals of Greek colonists and other Southern peoples, adopted or adapted the Ancient Greek motif of the feast of the dead, reversal, and protection/purification, integrating it into their own calendar that coincided with the transition into winter. The spread of Dionysian cults, even indirectly, explains the structural similarity between a festival linked to the "god of liberation and ecstatic state" Dionysus and a festival that signals the end of light.
The Timeless Need for Purification
Although Halloween today has taken on a strongly commercial and secular character, its root remains deeply human: the need for purification, the confrontation of the fear of death through parody (disguises), and the annual transcendence of the world's boundaries.
Whether it is the Celtic Samhain, the Ancient Greek Anthesteria, or the Christian "All Hallows' Eve," all these celebrations reflect the same universal anxiety and humanity's timeless effort to manage its relationship with mystery and the dead. Halloween, therefore, may not have been "born" in Greece, but it carries within the heart of its customs an ancient Mediterranean "soul" that connects it to Dionysus and the Athenians thousands of years ago. Ancient Greek thought offers a bright window into understanding our darkest festivities.
