Çatalhöyük

approx. 9400-9100 years a.a.

This article is based to a large extent on the wonderful research that the Prof. did. UAM, PhD, hab. Kamilla Pawłowska. Ref. The smells of Neolithic Çatalhöyük, Turkey: Time and space of human activity

It doesn't look like much from the plain. A low hill, with no particular form, with nothing that can anticipate the visitor to find a place where the equality-based organization existed.

Çatalhöyük has been there for over nine thousand years. Thirteen hectares of adobe stacked in the Konya plain, at the center of what we call Turkey today. At the time of its highest density, between 8,000 people lived on it. No streets. No temple. No king. The houses attached to each other as in the cell, the ceilings worked as squares, without cemeteries, temples or monumental constructions, even the dead were buried under the floor of the rooms where the living were sleeping, eating and giving birth.

To understand Çatalhöyük we must leave our modernity, allow us disorientation and also try to put aside the romanticism with which we see the past. Because Çatalhöyük sucked, but before we got into those aromas that would be unbearable for our nose, let's go to the structure of the site.

The houses of Çatalhöyük have no entrance to the ground. To access you have to go up to the roof and down a wooden staircase through a hole. There are no streets because they don't need them: the roof is the street, the square, the collective space. Inside, the rooms are small and without windows. The home burns dry manure cakes, the fuel available on the plain, and that specific, dense and low smoke, permeates the plaster walls, clothes and hair of those who sleep there. The layers of black soot on the white plaster record the years as an involuntary file. The only fresh air goes through the same hole where people come down and smoke up.

Why live like this, half buried, without natural light, without separation between smoke and sleep? Maybe because winters on Konya's plain reach less than 25 degrees. The shared walls remain warm. A house attached to five neighbors loses much less temperature than an isolated house. The roof as the only entrance also functions as a barrier against predators and the cold. Maybe that extreme density, living without physical separation between houses means living without the possibility of secretly accumulating, without being able to build something that others don't see. Architecture made opacity almost impossible. And that impossibility may have been precisely the mechanism that maintained egalitarianism for centuries.

When the eyes adapt to the darkness, the paintings appear. Large fields of intense red, geometric bands that are repeated with the artist's interpretation, animals of impossible proportions: bulls, deer, vultures, leopards. And by emerging directly from the wall, in slabs and in relief, the royal skulls of bovids with the horns intact. The animal is incorporated into the house architecture.

These paintings are renewed. When something important happens, a death, a birth, the wall is linked in white and repainted. Under today's cast there are scenes that no one has ever seen. Some houses accumulate dozens of layers. Art doesn't decorate space, it records its history.

On a wall at the deepest level of the site something different appeared: a grid of rectangles that someone interpreted as the houses of the settlement itself, and behind it, a bicuspid form with black dots that could be the erupting Hasan Dağı volcano, a hundred and thirty kilometres away. If the interpretation is correct, it is one of the first known maps of human history. Someone looked at their own world from the outside and drew it. And he chose to paint it next to what could destroy it. The paintings cover the walls. The dead occupy the ground.

The dead are buried under the platforms where the living sleep, inside the active house, with the family living on top. Over time the soil is opened to add to another, the bones of the former are reordered, some skulls are recovered, painted from red ocre and stored. There are houses with more than twenty individuals accumulated under the floor over generations. The house is the place where everyone who lived is still there.

The smell that this produced in the first days after a burial, in a space without windows, with the only hole in the roof, was part of domestic life. There was no way to separate it. The smoke of the manure, the fat boiling in the mud bowl, the animal skins hanging on the north wall, and below all that, the earth just removed. For those born there, that smell was just the smell of home. The same air that brought the smoke from the manure and the ground removed also brought roasted cereal, sheep fat boiling in mud, fermented almez. Smells that any nose would recognize as good, mixed without possible separation with those we would consider unbearable today. There was no way to choose one and rule out the other. They were the same air.

The settlement from the outside

From the roof, Çatalhöyük smells different. The middens, the common dumpsters located between houses and in abandoned buildings, accumulate decaying houses, faeces, ashes and bones. Dogs are around their edges. In some building without owner, a flock of sheep spend the night. The smoke of thousands of homes on simultaneously forms a low cloud on the mound. When the wind changes, it all comes at once.

For the modern visitor, unbearable. For those who lived there, invisible. The human olfactory system used to a constant stimulus stops recording it. What for our nose would be an alarm signal, for them was the sign that everything was still in place. The world was working.

olfactory functions

Incentive function - food assessment
The diet combined cereals (emmer wheat, bare barley), legumes (lentils, peas, veza) and animal products. The processing of these foods generated specific aromas: toast of grains and nuts, boiled of vegetables and meat, fermentation of plants.
The presence of potentially toxic wild species (e.g. Oenanthe - water cituta -) in the wetland environment suggests that the smell played a critical role in avoiding poisoning when collecting aquatic plants.

Hazard avoidance - detect threats
The risk of fire was high: adobe houses with flat wooden and plumbing ceilings, access by stairs, constant fires in homes and ovens. The smell of smoke was omnipresent, but a change in its intensity or the smell of burning could point to an accidental fire or a deliberate burning of garbage.
The presence of landfill (middens) between houses and in abandoned buildings generated intense odors of decomposing organic matter (remains of animals with soft tissues, faeces). The ability to perceive these odors was essential to avoid infection and maintain health in a dense settlement (13 ha, thousands of people).
Predators (bears, leopards, wolves) documented by bones and skins posed a real threat; the smell of these animals or their excrements near the settlement would have activated alert responses.

attachment and link - care chemistry
The burial under the house platforms meant that the living lived together with the remains of their ancestors. The smell of decomposition (controlled) and then the smell of bones and pigments was part of the daily atmosphere. This prolonged contact with family remains reinforced intergenerational attachment.
The maternal-child link is reflected in the burial of neonates and children within the houses on specific platforms. The smell of breast milk, wet hair and sweat of care should be part of the sensory experience that weaned the breeding ties.
The repetitive domestic architecture, with fixed homes, platforms and storage spaces, created a stable olfactory environment that associated safety with family odors.

Olfactory nodes

Olavender Geographies
Conditions met:

Fixed space anchor: Each house had its own combination of odors (smoke from its home, its adjacent garbage, its burials). The communal dump, the corrals in abandoned buildings and the rooftop food processing areas were localized olfactory seals.

Characterisation of the place: The general smell of the settlement —a mixture of manure smoke, waste and animal excrement— was an identifiable feature of Çatalhöyük, which distinguishes it from other sites.

Flexible patterns observed:

Activity profile: The smell of the waste was from the accumulation of remains of slaughter, cooking and human waste; the smell of the corrals, the stocking of ovicaprines in disused buildings.

Organic signature: The adjacent wetland (Çarşamba River) provided stalled water odors, junks, fish and aquatic birds, while the nearby steppe areas provided thyme odors, aromatic plants and wild herbivores excrements.

Limit marker: When crossing from the inside of a house (with its atmosphere filled with smoke and plaster) to the outside (with odors of garbage and manure), the olfactory change was abrupt. The boundaries between neighbourhoods could also be marked by the accumulation of garbage.

Guidance and navigation: The intense odors of the dumpsters or the corrals could serve as a reference to be placed in an urban fabric without clear streets.

Loss of identity of the place: The abandonment of a house involved the disappearance of its domestic odors (smoke, cooking, life), radically transforming the olfactory identity of that space.
