The Oldest Aged Kefir Cheese and the Tarim River Basin Mummies of Xiaohe Mudi in Northwest China

Xinjiang Uyghur Autonomous Region constitutes the northwesternmost extension of the People’s Republic of China in both bio-geographical and politico-administrative terms. The regional division contains the Gurbantünggüt, Kumtag, and Taklamakan Deserts. But in this southwestern portion of Xinjiang, place names whose spellings begin with the letter “T” serendipitously define the land and dominate the people. The three deserts indeed have in common proximity to the Tarim River Basin and the Tien Shan Mountains. They also include in their bio-histories outposts and stops along ancient China’s two-way Silk and Horse Trade Routes. It nevertheless is the geological interaction between the Taklamakan, the Tarim, and the Tien Shan that emerges most unforgettably in the existence and memories of ancient civilizations. 

The Tarim historically acts as one of Xinjiang’s natural attractions. The river claims dual titles as the region’s iconic water body and the Republic’s longest inland river. Waters converge to form and replenish the Tarim at:

• The source rivers -- the Aksu from the north, the Khotan from the south, and the Yarkand from the southwest;
• The tributary rivers, the Kashgar and the Muzat from the north.

But mountains define the river’s course and volume. The Tarim follows an easterly course of shifting banks and beds because of:

• Rain shadows cast by the drying, leeward side of the Himalayan Mountain Range;
• Sandwich effects from the Kunlun Shan to the south and the Tien Shan to the north.

The Tarim River Basin additionally claims as the internal drainage system’s prevailing geography and geology:

• Arid plains;
• Ethane-, methane-, natural gas-, petroleum-, and propane-rich sedimentary rocks;
• Salt lakes and marshes;
• Sand dunes and massifs;
• Sandy deserts;
• Wooded foothills and valleys.

Soils encourage forests, meadows, and peatlands. Vegetation exists as:

• Flowering plants (Apocynum venetum [dogbane], Glycyrrhiza inflata [licorice], Karelinia caspica [daisy], Lycium ruthenicum [Russian box-thorn], Oxytropis glabra [locoweed];
• Grasses (Aeluropus pungens, Calamagrostis pseudophragmites);
• Reeds (Phragmites australis);
• Sedges (Carex spp, Cyperus spp);
• Shrubs (Alhagi sparsifolia [camelthorn], Eleagnus spp [silverberry], Halimodendron halimodendron [Russian salt tree], Halostachys caspica [amaranth], Myricaria pulcherrima [tamarisk], Nitraria sibirica [Siberian nitre bush], Tamarix ramossissima [Salt cedar]);
• Trees (Populus euphratica [Euphrates poplar], Populus pruinosa [White-powdered desert poplar).

The basin challenges them with yearly rainfall averages of 0.47 inches (12 millimeters). Temperatures freeze the Tarim from December to March. They otherwise head toward 104°F (40°C). The environmental configuration consequently is supportive to:

• Artifact preservation;
• Cultural isolation;
• Garden oases;
• Natural mummification;
• Nomadic societies;
• Pastoral economies;
• Tribal government;
• Xeriscape agriculture.

The above-mentioned constellation obtains in the life cycles and natural histories of the mountain-climbing, oasis-hopping, plains-roaming carpenters, chefs, furriers, growers, herders, irrigators, milliners, morticians, shamans, shoemakers, tailors, and weavers whose remains fill cemeteries proximitous to:

• Beifang Mudi;
• Cherchen;
• Hami;
• Loulan;
• Subeixi;
• Xiaohe Mudi.

Xiaohe Mudi historically carries the names of:

• Ördek’s Necropolis;
• (Small River) Cemetery Number 5.

Its non-Chinese designations come from Swedish archaeologist Folke Bergman (1902 – 1946), as:

• Han Dynasty-dated, Juyan Region-buried, wood-stripped manuscript discover, 1930 – 1931;
• Sino-Swedish Northwest China Scientific Inspection Team expeditioner along with Stockholm-born Swedish explorer Dr. Sven Anders Hedin (February 19, 1865 – November 26, 1952);
• Xiaohe tomb complex explorer, 1934.

The four millennia-old cemetery conserves:

• Arrow shaft-like, poplar-carved, two feather-tufted pegs;
• Blade- or oar-ended, poplar-carved, red ochre-painted, tomb-marking posts;
• Bunched grasses, yellow hemp (Ephedra sinica) twigs;
• Cowhide-covered, overturned boat-like, poplar coffins;
• Mummified, fringed loincloth-donned men and fringed skirt-dressed women sporting felt caps, leather boots or moccasins, plaited or woven belts, and woven mantles;
• Plaited baskets.

The light-haired, light-skinned, long-nosed, slender-bodied, tall-built mummies articulate ancient, pre-Tarim Basin-mingled European and Siberian ancestries per analyses of:

• Mitochrondrial DNA;
• Y chromosomes.

Researchers conjecture as the mummies’ language Tokharian, proximitous to:

• Celtic linguistically;
• Indo-European’s Balto-Slavic and Indo-Iranian geographically.

They consider among the mummies’ missions -- as the wild Tarim River Basin’s lifetime civilizers -- the realization of perfect cheeses. Excavations and investigations since 2002 indeed identify the mummies as pioneers of:

• Dairy products among lactose-intolerant East Asians;
• Wheat in barley-planted East Asia.

The recipe of skimmed ruminant milk being curdled by bacteria (Lactobacillus kefiranofaciens) -- not the calf intestine enzyme rennet -- and fermented by yeast, is recognizable as:

• Cottage cheese-like in consistency;
• Kefir-like in fermentation method.

Scientists guesstimate that cheese-making occupies a 10,000-year-old niche in the history of human-palatable foods. They identify the emergence of the culinary endeavor with the domestication of sheep around 7500 B.C. Both activities therefore link with the last suspected departure points of the animal-loving of modernizing northwest China’s Tarim River Basin. Experts indeed ponder what artifacts and genetics verify regarding Central Asia’ most mysterious migrants:

• The Iranian plateau is their last hypothesized exit before their first steps on journeys of thousands of kilometers, miles, and years eastward;
• The river basin is their last known homeland.

Problem-solving the above two facts’ prequels and sequels undoubtedly requires following ancient, multi-directional trails of:

• Cheese-making;
• Fabric-weaving;
• Horse-riding;
• Leather-working;
• Livestock-herding;
• Oasis-founding;
• Wheat-growing;
• Wood-carving.

My special thanks to talented artists and photographers/concerned organizations who make their fine images available on the internet.

Boat-shaped coffin (Coffin 5.A) of Small River Cemetery: Body of mummified young man, resting on his back, was wrapped in yellow-white wool mantle, with wheat grains in small bag tied into mantle near mummy’s head.
Coffin’s lid of 10 short boards was covered by ox-hides “which had apparently been applied in a wet state because…when…hides were removed the lid came off with them. In Pl. VI-a…lid with the hides is seen lying to the right of the coffin.” (pp. 68-69)
