Adamgarh rock shelters

The Adamgarh Rock Shelters constitute a premier prehistoric and rock art complex in the Indian subcontinent. Located 2 kilometers southwest of the city of Narmadapuram (formerly Hoshangabad) in Madhya Pradesh, these shelters are situated on an isolated sandstone hillock rising above the southern bank of the Narmada River valley. Geologically, the hillock belongs to the Vindhyan sandstone formation. Chronologically, the stratigraphic layers at Adamgarh document a dense, continuous sequence of human occupation stretching from the Lower Palaeolithic, through the Middle Palaeolithic, and peaking significantly during the Mesolithic Age (circa 5000 BCE to 4000 BCE). The site is globally celebrated in South Asian archaeology for providing some of the earliest, empirical evidence of animal domestication in India.

Stratigraphic Profile and Tool Evolution

Systematically excavated by R.V. Joshi and A.K. Ghosh of the Archaeological Survey of India (ASI) in 1960–61, the trenches dug within and outside the shelters revealed a clear vertical sequence of cultural evolution.

Lower and Middle Palaeolithic Layers

The deepest strata at Adamgarh consist of a thick boulder conglomerate mixed with red clay.

• Tool Matrix: These layers yielded characteristic Lower Palaeolithic Acheulean tools, including heavy quartz handaxes, cleavers, and scrapers.
• Transition: The overlying layer showed a transition into a Middle Palaeolithic flake industry, where tools were manufactured from fine-grained jasper and chert, showcasing a gradual diminution in tool size.

The Mesolithic Stratum

Directly above the Palaeolithic deposits sits a 1.5-meter-thick layer of dark, organic soil rich in microlithic artifacts. This layer represents the most intensive phase of human occupation at Adamgarh. The stone tool toolkit found here reflects extreme specialization and resource optimization:

• The Lithic Assemblage: Artisans produced thousands of geometric and non-geometric microliths, including lunates (crescents), triangles, trapezes, micro-blades, and micro-borers.
• Raw Material Economy: The choice of raw materials shifted completely away from the local Vindhyan quartzites to imported river cobbles of chalcedony, agate, chert, and jasper, sourced from the bed of the nearby Narmada River. These materials permitted precise pressure flaking.

The Domestication Revolution

The most monumental contribution of the Adamgarh excavations to Indian prehistory is the recovery of a massive faunal assemblage from the Mesolithic layers. Over 25,000 animal bone fragments were retrieved and systematically analyzed.

Proving Early Animal Husbandry

The faunal analysis revealed that a significant portion of the bones belonged to domesticated animals. Along with the site of Bagor in Rajasthan, Adamgarh serves as the primary scientific proof that animal husbandry in India began during the Mesolithic phase, well before the transition to settled agricultural villages in the Neolithic era. The domestic species identified include:

• Bos indicus (Humped Zebu Cattle)
• Capra hircus (Domestic Goat)
• Ovis aries (Domestic Sheep)
• Sus scrofa domesticus (Domestic Pig)
• Canis familiaris (Domestic Dog)

Zoo-Archaeological Significance

The bones of these domesticated variants showed distinct cut marks, splitting for marrow extraction, and charring from open fires. This confirms that herding was systematically practiced to secure a predictable food and milk supply, supplementing traditional hunting and gathering strategies.

Wild Fauna Context

Alongside domestic herds, the wild animal remains indicate that the Mesolithic environment of the Narmada valley was lush, featuring mixed deciduous forests and open grasslands. The wild species identified include the Cervus unicolor (Sambar deer), Axis axis (Chital), Sus scrofa (Wild boar), Hystrix indica (Indian porcupine), and monitor lizards.

Prehistoric Rock Art and Visual Culture

The Adamgarh complex consists of 18 distinct rock shelters, many of which feature vibrant prehistoric rock paintings executed on the vertical sandstone walls and ceilings. The paintings span from the Mesolithic period well into the historical era.

Mesolithic Art Characteristics

• Themes and Depictions: The earliest artistic layer is characterized by dynamic narrative scenes. It illustrates group hunting expeditions, figures wielding bows and arrows, running animals, and communal dances.
• Superimposition: Historical paintings featuring caparisoned horses, warriors carrying metal swords, and early Brahmi inscriptions are superimposed directly over the older Mesolithic layers.
• Pigments and Techniques: The Mesolithic artists utilized natural mineral oxides. They prepared a paste by grinding red ochre (geru) or white clay with water or organic binders like animal fat or plant sap, applying it to the porous sandstone surfaces using crushed plant-fiber brushes.

Key Pioneer Archaeologist

• R.V. Joshi: The legendary Indian prehistorian whose scientific excavations at Adamgarh in 1960–61 established the stratigraphic chronology of the Narmada basin and contextualized the early timeline of pastoral economies in South Asia.
