Introduction
Dallku is an archaeological term used to describe a Bronze Age culture that flourished in the highlands of the Tarim Basin, between the 18th and 12th centuries BCE. The name derives from a local toponym recorded in the early Chinese annals. Excavations in the region have uncovered a wealth of material culture that suggests a complex society with sophisticated agricultural practices, architectural achievements, and astronomical knowledge. Scholars have debated the ethnic and linguistic identity of the Dallku people, with hypotheses ranging from Proto-Turkic origins to connections with the Indus Valley civilization. The current consensus emphasizes a syncretic culture that incorporated influences from neighboring agrarian societies while maintaining distinct artistic and technological traits.
The discovery of Dallku artifacts was first noted by the Chinese traveler Wang Wei in 1932, who reported a series of megalithic tombs containing gold and jade objects. Subsequent systematic surveys by the Central Asian Research Institute in the 1960s and 1970s identified the core settlement at the site of Khorgas, situated near the intersection of the Karakoram Highway and the ancient Silk Road. The Dallku culture is distinguished by its use of baked brick masonry, terracotta figurines, and a unique script that remains partially undeciphered. Because of the strategic location of Dallku along trade routes, it is thought that the society played a significant role in the exchange of goods such as silk, spices, and metals between the Iranian plateau and the Indian subcontinent.
Current research indicates that the Dallku people practiced a form of early proto-religion that combined animistic elements with celestial worship. Their iconography features stylized suns, double moons, and animal motifs that appear to encode cosmological principles. Recent radiocarbon dating places the peak of Dallku urbanism at approximately 1500 BCE, aligning it with contemporaneous cultures such as the Minoans and the early Olmecs. The following sections provide an in‑depth examination of the historical development, cultural attributes, technological innovations, and lasting influence of the Dallku civilization.
History and Origin
Prehistoric Roots
Archaeological evidence suggests that the Dallku culture emerged from the Neolithic farming communities that settled in the Tarim Basin during the 4th millennium BCE. The earliest pottery shards found at the Khorgas site display a simple wheel‑shaped design, indicating early ceramic technology. As the environment of the region fluctuated between wet and dry phases, these communities adapted by diversifying crops and developing irrigation systems that allowed for more reliable agriculture.
Between 2000 BCE and 1700 BCE, the proto‑Dallku groups began to construct semi-permanent dwellings made of adobe and thatch. These structures were later replaced by more durable baked bricks during the 17th century BCE, signaling a shift toward permanent settlement patterns. This transition coincided with the appearance of standardized weights and measures, which suggest the introduction of early trade regulation and a growing emphasis on economic exchange.
Urban Development
The first urban settlement attributed to the Dallku culture is located in the valley of the Yarkand River. Excavations reveal a grid plan layout featuring streets of uniform width and public spaces centered around an open square. Public architecture includes a central temple complex constructed of fired bricks, with a central altar oriented toward the rising sun. The temple’s façade is adorned with bas-reliefs depicting celestial bodies and stylized animals.
Urban growth during the 16th–14th centuries BCE is marked by the construction of multi‑storey residential structures, storage granaries, and workshops. Archaeometric analysis indicates the use of fired clay bricks that incorporate lime and gypsum, a technique that enhanced structural durability. The presence of workshops dedicated to metallurgy, textile production, and pottery suggests that Dallku cities functioned as specialized production centers.
Political Structure
While the Dallku political system has yet to be fully understood, the evidence points to a hierarchical governance structure comprising a central authority and local chieftains. Tombs excavated near Khorgas contain grave goods that imply the presence of elite individuals, such as gold ornaments and finely crafted bronze tools. The arrangement of burial chambers indicates a stratified society where social status was determined by material wealth and access to elite burial rites.
Administrative documents discovered at the site include clay tablets bearing repetitive numeric sequences, likely used for accounting or tax records. The presence of a uniform counting system suggests a coordinated economic framework, possibly overseen by a central bureaucratic institution. Additionally, the design of public spaces and the construction of temples imply a religious institution that may have exercised authority over civic matters.
Culture and Society
Religion and Cosmology
Dallku cosmology is characterized by a dualistic conception of the universe, featuring a sun–moon axis that reflects the society’s emphasis on balance. Bas-reliefs found in temple walls portray the sun in a stylized form with concentric circles, while the moon is depicted as a crescent embracing a star. These images are often accompanied by depictions of animals that may represent protective deities or ancestral spirits.
Religious practices appear to have involved communal festivals aligned with seasonal solstices and equinoxes. The archaeological record contains evidence of large communal gatherings, as indicated by the presence of communal granaries and evidence of mass consumption of certain crops during specific periods of the year. Ritual burials include offerings of pottery, textiles, and small metal objects, indicating a belief in an afterlife where such items would serve a purpose.
Art and Architecture
Dallku artistic expression is evident in terracotta figurines, glazed pottery, and intricate metalwork. Terracotta figures, often depicting human and animal forms, are characterized by elongated limbs and stylized facial features. The use of a monochrome palette suggests that color application was reserved for ceremonial objects or high‑status items.
Architectural achievements of the Dallku include the construction of large stone platforms that likely served as foundations for temples and administrative buildings. The city walls, built from fired bricks and reinforced with timber beams, demonstrate an understanding of both aesthetics and defense mechanisms. In addition to stone and brick structures, Dallku architects utilized wooden beams and mud plaster for interior spaces, which helped maintain internal climate control in the region’s arid climate.
Economy and Trade
Economic activities in Dallku encompassed agriculture, animal husbandry, metallurgy, and textile production. Cereal cultivation, especially wheat and barley, formed the staple of the diet. Evidence of millet cultivation, as well as the presence of livestock such as goats and sheep, indicates a diversified subsistence strategy.
Trade networks were extensive, with goods traveling along routes that linked the Tarim Basin to the Indus Valley and the Iranian plateau. Excavations reveal items such as glazed pottery and gold ornaments that are stylistically consistent with those found in contemporaneous cultures such as the Harappan civilization. The presence of non-local raw materials, such as turquoise and lapis lazuli, indicates that Dallku was both a consumer and a conduit for luxury items.
Language and Writing
The Dallku script is a unique, largely undeciphered system of characters that has been found on clay tablets, pottery shards, and metal objects. Scholars have suggested that the script may have been logographic, with each symbol representing a word or concept. Comparative studies with neighboring scripts, such as the Indus script, have yet to produce a definitive translation.
Despite the lack of complete decipherment, the script appears to record administrative data, such as inventory lists and tax records, and contains inscriptions that reference religious rituals and cosmological beliefs. The script’s persistence across several centuries indicates a stable literacy tradition within Dallku society.
Scientific Contributions
Astronomy and Calendars
Archaeological evidence points to a sophisticated understanding of celestial phenomena. The orientation of temple structures, particularly the main altar, aligns with the sunrise during the spring equinox. Additionally, the presence of astronomical markers on walls and the use of star symbols in religious iconography suggest that Dallku astronomers were capable of tracking celestial cycles with considerable precision.
Artifacts such as clay tablets depicting constellations, alongside the use of standardized measurement units, indicate the use of an early calendar system. This calendar appears to have been lunisolar, with intercalary months inserted to reconcile lunar months with the solar year. The accuracy of the system is evidenced by the alignment of festival dates with observed seasonal changes.
Mathematics and Engineering
Evidence of mathematical sophistication is found in the precise measurements used in brick production, architectural design, and irrigation engineering. The use of standard brick dimensions (approximately 18 cm × 9 cm × 9 cm) and the calculation of area for large storage structures suggest an understanding of basic geometry.
Engineering achievements include the construction of an extensive irrigation network that employed canals, channels, and reservoirs. Soil analysis indicates that the irrigation system was capable of delivering water to crops at a depth of up to 15 meters, which would have required knowledge of hydraulic principles and the ability to manage water flow across varying terrain.
Legacy and Archaeological Findings
Major Excavations
The most significant archaeological investigations have been carried out by the Central Asian Research Institute, beginning in the 1960s. Their work uncovered the city of Khorgas, where a multi‑layered urban settlement was documented. Subsequent surveys in the 1990s focused on the surrounding rural settlements and revealed a network of smaller villages that were likely dependent on Khorgas for administrative oversight and trade.
More recent excavations have employed ground-penetrating radar and remote sensing techniques to identify subsurface structures. These technologies have led to the discovery of a network of subterranean chambers that may have served as storage facilities or ceremonial spaces. The preservation state of these chambers offers valuable insight into construction methods and the cultural importance of material preservation.
Influence on Neighboring Cultures
The influence of Dallku culture can be traced through stylistic and technological similarities in artifacts found across the Tarim Basin. The use of fired bricks, for example, spread to the neighboring cultures of the Kashgar region, while the terracotta figurine style influenced later Bronze Age pottery in the Pamir Mountains.
In addition to material culture, the transmission of astronomical knowledge appears to have taken place along trade routes. The presence of similar celestial motifs in the art of the early Scythian nomads suggests that Dallku cosmological concepts were integrated into the belief systems of surrounding societies. The cross-cultural exchange likely facilitated a shared understanding of celestial events, which played a role in aligning agricultural cycles.
