If you’ve ever yearned to touch the very fabric of India’s ancient past—to feel the pulse of lives lived millennia ago—then let me take you to a place that etched itself into my memory: the Isko Caves in Jharkhand. These aren’t just rock formations. They’re a vibrant canvas painted by prehistoric hands, whispering tales of early human existence and spiritual continuity.

A Decade-Long Calling

My first brush with the legend of Isko’s rock art was nearly ten years ago. The mental images it conjured—ochre figures frozen in time, bearing witness to forgotten rituals—sparked an immediate desire to visit. My son, Judhajit, shared this fascination, and we made tentative plans. But life, as it often does, swept them aside. Still, the allure of Isko remained—a persistent whisper in the back of my mind.

Finally, on February 2nd, Judhajit had a rare off-day. We knew the time had come to answer that ancient call.

Unveiling the Historical Significance

The Isko Caves, also known as Isko Rock Art Site, are located near the village of Isko in the Barkagaon block of Hazaribagh district, approximately 45 kilometres from the district headquarters. Situated on the Hazaribagh Plateau at an elevation of around 600 metres above sea level, the site is surrounded by dense sal forests and rolling hills typical of the Chotanagpur Plateau region.

The site was first identified in the 1980s by local archaeologists, but it remained largely unknown until the 1990s, when it began to attract wider scholarly attention. Among those who played a key role in bringing the Isko Caves into public consciousness was the Jesuit priest Fr. Tony Herbert, whose early observations drew interest to the site. This was followed by systematic surveys undertaken by the Archaeological Survey of India (ASI) and state archaeological departments. In 1991, environmentalist Bulu Imam further helped introduce these remarkable natural shelters to a wider national and international audience.

Radiocarbon dating and stylistic analysis suggest that the artworks belong to multiple phases of human occupation. The earliest paintings, generally assigned to the Mesolithic period (circa 8000–4000 BCE), consist of simple geometric designs and animal figures that reflect the subsistence patterns and symbolic world of early hunter-gatherer communities.

The paintings are often described as belonging to a Meso-Chalcolithic horizon, supported by the discovery of both copper and lithic technologies in the surrounding area. Archaeological investigations have also recovered a range of stone tools from the site, including hand axes, choppers, microliths, blades, points, and scrapers, underscoring the long and continuous human presence in these shelters.

Later superimposed layers, associated with the Chalcolithic and subsequent cultural phases, indicate that the shelters remained in use for centuries, with successive generations adding new artistic expressions to the rock surfaces. Some scholars have proposed even earlier origins for portions of the site, linking certain remains to the Middle Paleolithic period (circa 300,000 to 30,000 years ago).

Isko is part of a broader network of prehistoric rock art sites in Jharkhand, including nearby Satpahar and Thethangi, collectively forming one of India’s richest concentrations of Mesolithic art outside Bhimbetka (a UNESCO World Heritage Site in Madhya Pradesh).

A Living Tradition

India’s connection to its ancient past isn’t confined to museum exhibits. In regions like Jharkhand, Madhya Pradesh, Orissa, and Karnataka, ethnic communities still practice forms of rock art during rituals. Think of the vibrant handprints adorning gates during births and marriages—a direct link to the artistic impulses of their prehistoric forebears.

The star attraction of Isko is its vivid rock paintings, created primarily in red ochre (hematite), with occasional use of white and yellow pigments derived from local minerals. These natural colors were applied directly onto the rough sandstone surfaces using fingers, twigs, or brushes fashioned from animal hair. The ancient artists typically began by sketching an outline and then carefully filling the interior with pigment. The strokes range from delicate fine lines to broader bands, and in some cases the figures are accentuated by outer contours in contrasting shades.

These paintings offer a rare window into the culture of their creators, revealing not only artistic skill but also insights into the surrounding ecology, daily life, and spiritual beliefs of the time. Themes of hunting, animal life, ritual, and human interaction suggest a close relationship between early communities and the natural world around them.

Isko lies within the ancestral landscape of the Oraon and Munda communities, whose oral traditions still preserve echoes of hunting lore, nature worship, and seasonal celebrations. The wider region of Hazaribagh remains a living cultural mosaic, where village walls are decorated with traditional mural forms such as Khovar and Sohrai. These contemporary artistic traditions often mirror motifs found in the caves, creating a remarkable thread of continuity that links the present with a heritage stretching back thousands of years.

The Journey to Isko Caves

Our journey to Isko on that February morning was a family affair. My daughter-in-law, Tania, joined Judhajit and me, our anticipation building with every kilometre. Despite my years of longing to visit, this was our first attempt, and we wisely sought the guidance of Subhashis Das, a celebrated explorer of megalithic sites, to navigate the less-trodden paths.

The drive from Hazaribagh was a balm to the soul, a tapestry of verdant landscapes and winding roads unfolding before us. As we neared Barkagaon, we relied on the kindness of locals for directions, their insights proving far more reliable than the sporadic and often misleading signage.

“Barkagaon?” a shopkeeper echoed, his eyes crinkling at the corners. “Ah, Isko is that way,” he gestured with a knowing smile, recounting his own visit just days prior. While Google Maps offered a digital route, the wisdom of the local community proved invaluable in this rural heartland. It struck me then how much the Jharkhand government could do to promote this incredible heritage by simply installing adequate signage. There were moments of confusion, a government sign pointing one way while Google suggested another. Trusting the local advice, and thankfully, Google’s eventual accuracy, we finally reached Isko village.

A welcoming gate marked the entrance, and we drove along a short metalled road that abruptly ended at a small ditch. A few cemented chairs sat forlornly, marking the limit of our vehicular journey.

Our destination lay further ahead, nestled amidst a landscape of rocky outcrops and the graceful sway of Sal trees. And yet, even here, at the very threshold of this historical wonder, there was no sign to guide us towards the cave.

The Trek to Marwadwar Cave

With patchy network coverage rendering Google Maps unreliable, we ventured on foot, following a faint trail into the forest. The air was alive with rustling leaves and birdsong. After a long walk, we emerged onto a rocky expanse—a natural vantage point with a sliver of network. A quick check confirmed our fears: we had veered off course.

Retracing our steps, we encountered a local villager emerging from the dense foliage. Hope surged within us. “The path to the cave?” we inquired. He readily agreed to guide us, explaining that the cave we were seeking, adorned with the famed rock art, was about a kilometre from another nearby rock shelter known as Marwadwar.

Marwadwar, he said, was steeped in legend—a haven for a newlywed king and queen. Nearby flowed the Marwatari river, its name forever linked to the cave where their union took place. Later, I recalled Mr. Das’s insight: such caves symbolised the “womb of the Great Mother,” remnants of ancient fertility cults.

Even today, locals revere these caves as sacred spaces, inhabited by spirits and deities. Rituals and prayers are still offered here, especially during festivals—a testament to the enduring spiritual connection to this ancient land.

Trek to Isko Caves

After exploring the shelter of Marwadwar, we made our way towards Isko village, our quest for the rock art rekindled. A group of children were playing by the roadside, their laughter echoing in the tranquil air. I approached them, inquiring about the location of the rock art site. Their innocent eyes lit up, and they eagerly pointed us in the right direction. Not only that, but three of them – Jiwan Munda, Pawan Munda, and Hans Munda – volunteered to be our guides, leading us through the winding paths of their village towards the ancient masterpieces.

Witnessing Ancient Masterpieces

The principal rock shelter rises to a height of nearly 20 feet and is divided into four interconnected sections. The painted surface extends approximately 30.5 metres in length and about 2.25 metres in vertical width, forming a long natural gallery across the sandstone wall. Its location is particularly striking, positioned at the point where the village gradually gives way to the surrounding forest, creating a symbolic threshold between human settlement and wilderness.

And then, there it was. Standing before the 10,000-year-old paintings, bathed in the soft glow of the afternoon sun, felt like stepping through a portal in time. The rock face was a canvas teeming with life – depictions of ritual dances, hunting expeditions, and scenes of daily existence, all rendered in vibrant natural pigments of red ochre, yellow ochre, white kaolin, and black manganese.

The artistry was breathtaking, the expressions captured in these ancient strokes resonating with a profound sense of human experience and spirituality. It was a privilege to witness such enduring creativity, a testament to the rich cultural and social lives of those who walked this land so long ago.

The rock paintings of Isko Caves are among the oldest and finest examples of prehistoric art in India. They depict various scenes of hunting, fishing, dancing, fighting and ritual activities. The paintings are made with natural pigments such as red ochre, yellow ochre, white kaolin and black manganese. The paintings show a high degree of artistic skill and expression, as well as a rich cultural and social life of the ancient people.

The surrounding indigenous communities continue to live in traditional mud houses, preserving a way of life closely tied to the landscape. Locally, the sandstone shelter is known as Kohbar because the paintings are believed to resemble the ceremonial motifs painted on the inner and outer walls of the bridal chamber in tribal homes, where newly married couples traditionally meet. This association gives the site not only archaeological significance but also a continuing cultural resonance within the community.

A Magico-Ritual Connection

Some rock art sites (like Thethangi, Isko, Rahaman, and Sidpa) of North Karanpura valley also show the magico-ritual connection between present-day ethnic communities and the rock art site. These caves are more than historical sites; they are sacred spaces for the local community, who regard them as the abode of ancestral spirits and deities. Rituals are still performed here, blending ancient beliefs with contemporary practices.

As Shubham Rajak eloquently puts it, the anthropomorphic figures found in Isko and other sites like Thethangi, Rahaman, and Sidpa in the North Karanpura valley likely held multiple meanings for their creators, representing shamans, ancestors, deities, and mythical characters all at once. The fact that similar figures and symbols persist in the ethnic art of the region provides an invaluable link, allowing us to interpret the archaeological record through the lens of living cultural traditions.

The Significance of Isko Caves

The Isko Caves hold immense significance for both archaeology and anthropology. They offer tangible evidence of prehistoric human habitation in Jharkhand, and the rock art provides crucial insights into the evolution of human creativity and communication. These caves serve as a powerful reminder of the ingenuity and adaptability of our early ancestors, who found ways to express their world and document their experiences through the enduring power of art.

A Visit to Remember

In an era of digital distractions, the Isko Caves invite reflection on humanity’s artistic origins. Far from crowded tourist circuits, they offer solitude amid nature, where one can trace fingers over 10,000-year-old handprints and ponder the universal human impulse to create. As Jharkhand pushes for greater recognition of its heritage, Isko stands poised to join India’s archaeological map— a must-visit for anyone seeking the roots of civilisation in the subcontinent’s tribal soul.

As we bid farewell to Isko, a profound sense of awe mingled with a renewed commitment to protect and cherish this incredible heritage. The whispers from the stone echoed in our hearts, a reminder of the long and fascinating journey of humankind on this ancient land.

Postscript (After our visit & publication of this post)

Declared a national monument on World Heritage Day, April 18, 2023, the Isko Caves deserve greater awareness and responsible tourism to ensure their long-term preservation. While the Archaeological Survey of India (ASI) and dedicated conservationists like Subhashis Das, Bulu Imam have made efforts to protect this invaluable heritage, much more needs to be done. It is our collective responsibility to respect the sanctity of the site, refraining from touching the delicate paintings, avoiding littering, and minimising our impact on this fragile ecosystem.
