To look upon the archaeological record of humanity is to look upon a vast, global network of tears. As an anthropological historian, my work is a form of deep-time listening. When we strip away the distinct material textures of the past — the carved stone slabs of the Valley of Mexico, the moss-grown dolmens of Atlantic Europe, the shell-middens of the Australian coast — we find a single, repeating human pulse. It is the pulse of a species that loves deeply, loses inevitably, and must figure out what to do with the heavy, destabilising energy left behind when a life ends.

In our contemporary, individualistic landscape, death has been sanitised, professionalised, and hidden away. We are expected to grieve quietly, neatly, and with an eye toward a rapid return to productivity. But across the vast stretches of ancient history, our ancestors operated under a starkly different, far more urgent realisation: unexpressed grief is a dangerous, toxic entity.

To the ancient mind, grief was not an internal, passive emotional state to be managed with silent resilience. It was a volatile psychic current, a disruption in the local ecology, and a literal weight on both the living community and the departing soul. Left trapped within the human chest, it was believed to poison the body, drive the mind to madness, shatter the social fabric, and leave the spirit of the deceased stranded in an agonising limbo.

What we observe when we study seemingly unconnected civilisations across human history is a phenomenon known as convergent cultural evolution. Without any physical contact, separated by thousands of miles and vast oceans of time, disparate societies independently engineered identical, highly effective social and spiritual technologies to handle this danger. They did not suppress the dark waters of loss; they built deep, communal channels for them to flow through.

The danger of unexpressed grief: two views

The traditional view treated grief as:

  • •A volatile psychic current
  • •Poisonous if trapped inside
  • •A shared, communal burden
  • •Essential spiritual labour

The modern view treats grief as:

  • •An internal, passive emotion
  • •Something to be sanitised and privatised
  • •An individualised problem
  • •A disruption to productivity

1. The Anatomy of Convergent Grief Rituals

When we look across history, the structural similarities in grief rituals between entirely isolated cultures are staggering. It is a reality that invites us to look past mere historical coincidence and see a universal blueprint for human healing. Consider the striking structural parallels between the ancient continental Celts of the European Iron Age and the Aztecs of Mesoamerica half a millennium later.

These cultures shared no common trade routes, no linguistic roots, and no shared ancestors within tens of thousands of years. Yet both civilisations independently concluded that the immediate aftermath of a death required a loud, raw, public, and highly coordinated emotional explosion.

The same pattern repeats across four widely separated traditions:

  • •Ancient Celts — Keening (Caoineadh) and the festive wake, lasting several days to weeks. Its rationale: propelling the soul into the Otherworld and maintaining the cosmic cycle.
  • •Aztecs — Extended public weeping and effigy burning, sustained for up to 80 days. Its rationale: assisting the soul through the trials of Mictlan, the underworld.
  • •Ancient Egyptians — Professional moirology for the full duration of mummification. Its rationale: embodying the cosmic grief of Isis and protecting the transition to Osiris.
  • •Traditional Chinese — Ku Sang (ritual wailing) across a multi-day funeral sequence. Its rationale: demonstrating filial piety and clearing the path to the ancestor realm.

For both the Celtic clansman and the Aztec warrior, a silent household was a terrifying omen. Silence meant the grief was stagnating, curdling inside the living. To prevent this, both cultures used structural anchors: intense public weeping, multi-day communal vigils, and the deliberate creation of a festive atmosphere alongside deep sorrow to ground the community while a soul transitioned between worlds.

2. The Techne of the Tears: The Role of Professional Mourners

Perhaps the most fascinating manifestation of this universal human blueprint is the widespread, independent development of professional mourning — a concept that feels utterly foreign, if not transactional, to the modern Western mind. Why would a family hire strangers to weep for their beloved?

The answer lies in a profound understanding of psychological friction. In the immediate paralysis of shock and devastating loss, the deeply bereaved are often frozen. Their throats are constricted; their pain is a hard, unyielding knot. The ancients understood that this frozen state is where the danger lies.

To break the ice, they brought in emotional specialists. In Ancient Egypt, these were women who embodied the archetype of the goddess sisters Isis and Nephthys. They shaved their heads, covered their arms in dirt, and walked before the funeral procession — shrieking, beating their breasts, and weeping uncontrollably. In the Mediterranean, the Roman praeficae and Greek moirologists sang sweeping, guttural laments that filled the streets with an undeniable, suffocating atmosphere of tragedy.

The mechanism was a deliberate transfer of permission:

  • •The bereaved family — frozen in trauma, socially constricted, unable to break out of their paralysis.
  • •The professional mourner — vocalises the raw pain, shatters the silence, and grants the family permission to feel.
  • •The result — a cathartic, communal release that the family could not have reached alone.

This was not a hollow performance; it was an act of sacred, psychological labour. The professional mourners acted as a cultural release valve. By producing a loud, externalised, and socially sanctioned manifestation of agony, they shattered the polite, fragile silence of the community. They gave the family explicit permission to lose their minds, to scream, and to drop their social armour. The performance of the stranger unlocked the authentic, healing crisis of the loved one.

3. The Spiritual Necessity of Motion: Grief as a Rite of Passage

To understand why our ancestors feared unexpressed grief so deeply, we must step outside the modern, materialistic view of the universe and look through a spiritual lens. To the ancient world, death was never a sudden, absolute cut-off point. It was a complex, perilous journey — a migration of consciousness from this material plane to an immaterial one.

In his foundational anthropological work, Arnold van Gennep identified the three-part structure of all rites of passage:

  • •Separation — the individual leaves their old status behind.
  • •Liminality — a transitional, threshold state where they are neither here nor there.
  • •Aggregation — reintegration into a new role or world.

Ancient funeral rituals were explicitly designed to navigate this highly volatile liminal phase. When a person died, their soul did not instantly arrive at its destination; it was hovering on the threshold.

In the Aboriginal Australian tradition of "Sorry Business," this liminality is treated with immense spiritual caution. The spirit of the dead is believed to linger close to the earth — confused, vulnerable, and easily pulled back by the earthly attachments of the living. To protect the spirit, strict taboos were put in place: the dead person’s name could not be spoken, and their image could not be looked upon. Smoking ceremonies using native plants were performed to cleanse the physical spaces they had inhabited. This was not an act of forgetting; it was an act of aggressive spiritual boundary-keeping. If the living held onto their grief silently, secretly wishing for the person’s physical return, they would trap the spirit in the earthly realm, preventing its return to the Dreaming.

The journey runs in one direction only: from physical life, to the soul hovering at the liminal threshold, and finally into the ancestral realm — the Dreaming, or the Otherworld. The mourners’ task is to block the backward path with ritual, smoke, and taboo, so the spirit cannot be dragged home.

Similarly, the Celtic practice of keening (Caoineadh) — a vocalisation that sat on the razor’s edge between a song, a cry, and a wild animal shriek — was viewed as literal fuel for the soul’s journey. The keen was led by a woman who stood over the body, singing the lineage of the dead, recounting their deeds, and unleashing a torrent of raw, sonic sorrow. The community would join in on the repeating choruses.

This acoustic wall of grief was believed to open a portal between this world and the Otherworld, providing the psychic momentum necessary to propel the soul across the veil. If the family repressed their grief, if they failed to keen, the path remained closed. The soul would remain bound to the rotting corpse, transforming into a restless, malevolent entity born of spiritual stagnation.

4. The Somatic Toll: What the Body Remembers

While ancient peoples used spiritual language to describe the dangers of unexpressed grief, modern somatic psychology and neuroscience are beginning to validate their warnings using the language of biology. When we suppress a profound emotional shock, the nervous system does not simply delete the data; it buries it alive in our tissues.

During a major loss, the brain is flooded with a cocktail of stress hormones, primarily cortisol and adrenaline. In a natural, ancient setting, the immediate, explosive somatic responses — screaming, violent shaking, weeping, and thrashing — are the body’s instinctual methods of burning off this neurochemical surge.

When a modern individual is socialised to "stay strong," to hold it together, and to limit their weeping to a quiet, dignified tear at a graveside, the nervous system remains trapped in a state of incomplete, low-grade freeze. The stress response has no path to completion. Over months and years, this unreleased strain tends to manifest physically:

  • •It dysregulates the grieving brain’s stress-response pathways.
  • •It taxes the immune system and is associated with chronic inflammation.
  • •It hardens into muscular tension and digestive issues, and is linked to longer-term difficulties such as Prolonged Grief Disorder (PGD).

The Aztecs, Egyptians, and Celts did not have access to functional MRI machines, but they possessed a profound, empirical understanding of the human body. They knew that if you do not give the body a physical, loud, and exhausting avenue to expel the horror of death, the horror will eat the body from the inside out.

They understood that heavy, visceral sorrow must be physically moved out through the breath, the throat, and the tear ducts. By the end of an ancient multi-day wake or an 80-day Aztec mourning period, the community was physically exhausted. Their bodies had run a marathon of sorrow, leaving them completely drained but entirely clear. They had safely metabolised the poison of loss.

5. Reclaiming the Sacred Architecture of Loss

We live in an age of unprecedented material comfort, yet we are profoundly impoverished when it comes to the architecture of the soul. By privatising grief — by turning it into a shameful, lonely secret to be processed behind closed doors — we have cut ourselves off from the ancient medicine of our ancestors.

The contrast between the two ecosystems is stark. The ancient communal model was public and visible, offered professional emotional aid, made room for boundless somatic release, and kept its focus on the cosmic transition. The modern privatised model is private and hidden, leaves people to solitary processing, permits only a controlled and polite display, and narrows its focus to a clinical checklist.

The lesson we must take from the convergent wisdom of the global past is that grief is not an individual problem to be fixed; it is a communal reality to be honoured. It is a form of sacred, essential labour that requires structure, witnesses, and time.

We do not need to resurrect the literal practices of the Roman praeficae or the Aztec effigy burners, but we desperately need to reclaim the underlying philosophy of their designs. We must begin to build spaces where we can be unapologetically, loudly, and safely broken in the presence of others. We must learn to view our tears not as a sign of emotional weakness, but as the ancient, alchemical element that washes away spiritual stagnation.

Because when someone we love dies, the love we carried for them does not evaporate. It transforms, instantly, into grief. And if we refuse to let that grief speak — if we refuse to let it scream, sing, or dance its way out into the world — it can slowly corrode the temple of the self. The ancients knew this truth in their bones: to steady the living and to free the dead, the grief must be allowed to move.

6. The First Nations of North America: The Wiping of the Tears

Among the hundreds of diverse Indigenous nations across North America — from the Lakota of the Great Plains to the Haudenosaunee (Iroquois) of the Northeast Woodlands — grief was never treated as a private, psychological wound. It was viewed as a spiritual fire that, if left untended, would burn down both the individual and the harmony of the entire community.

To prevent this, First Nations peoples developed highly structured, somatic, and relational rituals designed to actively absorb and transform the heavy energy of loss — moving from somatic shock, through communal satiation and ritual resolution, to integration and rebirth.

The somatic anchor: physical alteration

In many Plains and Woodlands cultures, the onset of grief was met with an immediate, drastic physical transformation. Mourners would cut their hair short — an act of profound somatic and symbolic significance, as hair is often viewed as an extension of one’s spirit and memories. By cutting the hair, the mourner physically shed their past life with the deceased.

Among some nations, individuals would slash their skin or cover themselves in ashes and clay. This was not a hollow act of self-destruction; it was a profound externalisation of internal trauma. The physical body was altered to accurately mirror the broken state of the soul, ensuring that the grief could not hide or fester in a polite, unexpressed guise.

The law of shared weight: the feast and the giveaway

A core tenet of many First Nations philosophies is that a weight too heavy for one person must be divided among the collective. Following a death, a family would often enter a prolonged period of mourning lasting up to a year. At the end of this period, the community would gather for a great feast and a ritual known as the "Giveaway."

The grieving family would give away virtually all of their material possessions — blankets, horses, beadwork, and tools — to those who had supported them during their darkest hours. Anthropologically, this served a dual purpose:

  • •It prevented the stagnant accumulation of material objects that would tie the deceased’s spirit to the physical plane.
  • •It structurally bonded the community, ensuring that the vulnerability of the grieving family became the strength of the collective.

The alchemical resolution: the wiping of the tears

Perhaps the most beautiful spiritual technology found among First Nations peoples is the Lakota ceremonial "Wiping of the Tears." After a year of intense, permissible mourning, the community formally gathered around the bereaved family. Medicine people or respected elders would use sacred eagle feathers and water to literally and ritually wipe the tears from the faces of the mourners.

This ceremony marked the official end of the acute mourning period. It was a communal declaration that the heavy work of grieving had been fully and properly expressed. The family’s hair would be combed, they would be dressed in bright, clean clothing, and they were formally welcomed back into the dance of life.

The universal blueprint completed

When we place the First Nations alongside the Celts, the Aztecs, the Egyptians, and the Aboriginal Australians, the universal blueprint becomes undeniable. The Lakota "Wiping of the Tears" operates on the exact same psychological and spiritual frequency as the Celtic wake or the Aztec public weeping.

Every one of these cultures understood that you cannot intellectualise grief away. You must scream it out, sweat it out, give it away, and physically wash it from your face in the presence of witnesses who love you. Unexpressed grief is dangerous because it isolates the self; ancient rituals heal because they remind the broken individual that they are part of a larger, eternal circle.
