Carved in stone: how inscriptions became India's most honest historians

Court poets flattered kings; stone did not. When an emperor carved his policies on a rock face, or a merchant recorded a donation on a cave wall, they were writing for eternity, and accidentally writing our history textbooks. Epigraphy (the study of inscriptions) is how we know the Mauryas, the Guptas and the Satavahanas at all. Learn the landmark stones, and ancient India stops being a blur.

The decipherment that unlocked Indian history

Until 1837, India's oldest stones were beautiful mysteries. Then British antiquarian James Prinsep deciphered the Brahmi script, and the Ashokan inscriptions suddenly spoke, revealing an emperor, his administration, and his moral philosophy in his own words. The Ashokan corpus remains the earliest large decipherable body of inscriptions in India, the foundation stone of all ancient Indian political history.

Ashoka's billboards: edicts across an empire

Ashoka's inscriptions, carved on rocks, pillars and cave walls across the subcontinent, fall into a neat taxonomy that UPSC loves:

• 14 Major Rock Edicts: Ashoka's Dhamma policy, non-violence, religious tolerance, welfare. Found at Girnar (Gujarat), Kalsi (Uttarakhand), Dhauli (Odisha) and others.
• Minor Rock Edicts: personal messages, his conversion, moral conduct, missions. At Maski, Gavimath, Palkigundu (Karnataka) and Bairat (Rajasthan). The Maski edict is special: it names the author as Ashoka, confirming that 'Devanampiya Piyadasi' of the other edicts was indeed him.
• 7 Major Pillar Edicts: administration and public welfare, Delhi-Topra, Delhi-Meerut, Allahabad-Kosam.
• Minor Pillar Edicts: his reverence for Buddhism and instructions to the Sangha, Sanchi, Sarnath.
• Cave inscriptions: grants to the Ajivika sect at Barabar Hills (Bihar).

The language was overwhelmingly Prakrit; the scripts were Brahmi (most of India), Kharosthi (the north-west), and Greek and Aramaic in the Kandahar inscriptions of Afghanistan, a linguistic map of the empire itself. Their significance: they document Mauryan governance, the state-sponsored spread of Buddhism to Sri Lanka and Central Asia, and an early Indian cosmopolitanism.

Prashastis: kings praising kings

A prashasti is a eulogy in stone, and the two most famous are exam staples. The Allahabad pillar inscription (the Prayag Prashasti), composed by Harisena, details Samudragupta's conquests and is our primary source for the Gupta empire's extent. The Aihole inscription, composed by the Jain court poet Ravikirti, celebrates Pulakesin II of the Chalukyas, his defeat of Harsha, his title Parameswara, written in Sanskrit and Old Kannada script, a landmark of early Kannada epigraphy.

Donors, dynasts and layered stones

Beyond the famous two, keep these on your map: the Hathigumpha inscription (Udayagiri, Odisha) of King Kharavela (1st century BCE), in Brahmi, chronicling a Jain king's reign; the Mehrauli iron pillar inscription near the Qutub Minar, enumerating the exploits of a king called Chandra (identified with Chandragupta II Vikramaditya); and the Junagadh rock inscription of the Shaka ruler Rudradaman (c. 150 CE), one of the earliest long inscriptions in Sanskrit, recording the repair of the Sudarshana lake, on a rock that also carries Mauryan and Gupta layers.

Reading scripts: Brahmi and Kharosthi

Two scripts dominate early Indian epigraphy. Brahmi, written left to right, is the mother script of nearly all later Indian scripts; Kharosthi, written right to left, served the north-west. Both were cracked open through the Ashokan edicts, which is why a single emperor's moral proclamations became the Rosetta Stone of Indian history.

Ashoka's four edict families

Ashoka's inscriptions fall into four families, grouped by the surface they were carved on: Major Rock Edicts (about fourteen long proclamations on frontiers), Minor Rock Edicts (shorter, personal, on about fifteen rocks), Major Pillar Edicts (seven, on polished single-stone pillars), and Minor Pillar Edicts (five, from the earlier part of his reign). Together they number about thirty-three separate writings.

The scripts tell their own story. Most edicts are in Prakrit written in Brahmi, read left to right. In the north-west, Mansehra and Shahbazgarhi use Kharosthi, read right to left. Edicts in Afghanistan are bilingual, in Greek and Aramaic: the Kandahar rock inscription is the classic example. James Prinsep decoded the Brahmi of the Ashokan edicts in 1837, which is what made ancient Indian political history readable at all.

Ashoka's personal name appears in only three minor rock edicts, at Maski, Gujarra and Nittur. Everywhere else he calls himself Devanampiya Piyadasi, Beloved of the Gods.

The edicts and inscriptions that matter: at a glance

Three definitions worth keeping

• Epigraphy: the study of inscriptions engraved on stone, metal, pillars and copper plates, the primary written source for large stretches of Indian history
• Prashasti: an inscription composed in formal praise of a king or patron, blending genealogy, conquests and eulogy, useful and to be read with caution
• Edict: an official proclamation of a ruler, like Ashoka's rock and pillar edicts addressed directly to his subjects across the empire

Key Terms

• Epigraphy: Epigraphy is the study of inscriptions engraved on stone, metal, pillars and copper plates. For Indian history it is the primary written source of the ancient period, preserving royal edicts, land grants and religious records, and is studied alongside numismatics and archaeology. The Archaeological Survey of India publishes epigraphical finds in the journal Epigraphia Indica. For UPSC, it is a standard method in ancient-history source questions. The Ashokan rock and pillar edicts, deciphered by James Prinsep in 1837, are epigraphy's most famous Indian application.
• James Prinsep: James Prinsep was the British antiquarian and secretary of the Asiatic Society of Bengal who deciphered the Brahmi script in 1837, using bilingual Greek-Brahmi coins of Indo-Greek kings as his key. His breakthrough unlocked Ashoka's edicts and founded scientific Indian epigraphy. For UPSC, Prinsep explains how ancient Indian history was recovered from stone, coins and seals. Deciphering Brahmi let scholars read Ashoka's rock edicts, revealing the Mauryan emperor's dhamma policy for the first time.
• Brahmi script: Brahmi is one of the oldest writing systems of India, used from about the 3rd century BCE and the script of Ashoka's edicts. Written left to right, it is the ancestor of most modern Indian scripts, including Devanagari. It was deciphered in 1837 by James Prinsep, which unlocked Ashokan history for modern scholarship. For UPSC, Brahmi is a staple of ancient Indian epigraphy and art-and-culture questions. James Prinsep's 1837 decipherment of the script on Ashoka's edicts.
• earliest large decipherable body of inscriptions: The earliest large decipherable body of inscriptions in India is the corpus of Ashokan edicts, more than thirty proclamations carved on rocks, pillars and cave walls across the subcontinent in the third century BCE. Written mainly in Prakrit using the Brahmi script in the heartland and Kharosthi in the northwest, they were deciphered by James Prinsep in 1837. They matter for UPSC as the foundational source for Mauryan administration, Dhamma and early Indian epigraphy. the Maski rock edict, which names Ashoka
• 14 Major Rock Edicts: Ashoka's fourteen Major Rock Edicts, inscribed on rock faces across the Mauryan empire in Prakrit using the Brahmi script, proclaiming his policy of dhamma: non-violence, religious tolerance, welfare of people and animals, and the duties of officials. For UPSC, they are the primary source for Mauryan administration and Ashoka's post-Kalinga transformation. Major Rock Edict XIII, which expresses Ashoka's remorse over the slaughter and deportations of the Kalinga war.
• Minor Rock Edicts: Minor Rock Edicts are Ashoka's shorter rock inscriptions, issued early in his reign and found across the empire from Maski and Brahmagiri in Karnataka to sites in Madhya Pradesh and beyond. The Maski edict is famous for naming the king personally as 'Ashoka', confirming the identity behind the title Devanampriya. For UPSC, they are core prelims facts on Mauryan epigraphy, Ashokan dhamma and the decipherment of Brahmi. Maski edict, Raichur district, Karnataka
• Maski edict: The Maski edict is a minor rock edict of Ashoka at Maski in Karnataka's Raichur district, and it is historically decisive because it names 'Devanampiya Asoka', proving that the 'Piyadasi' of the edicts and Ashoka are the same king. It records his increasing zeal for Buddhism and the sangha. UPSC relevance: GS-1 ancient India; a classic prelims question on which edict names Ashoka. Names 'Devanampiya Asoka', confirming Piyadasi is Ashoka
• Ashoka: Ashoka is the Mauryan emperor (reigned c. 268 to 232 BCE) whose remorse after the Kalinga war of c. 261 BCE led him to adopt Buddhism and the policy of Dhamma. His rock and pillar edicts across the subcontinent are India's earliest deciphered written records and a primary source for Mauryan administration. He is the most asked-about ruler in UPSC ancient history. the Major Rock Edicts, such as the one at Girnar.
• 7 Major Pillar Edicts: 7 Major Pillar Edicts is the set of seven edicts of Emperor Ashoka inscribed on stone pillars at sites including Topra, Meerut, Allahabad, Lauriya-Araraj, Lauriya-Nandangarh and Rampurva. They proclaim Ashoka's dhamma, his welfare measures and his remorse after the Kalinga war. For UPSC, the pillar edicts are the core primary source for the Mauryan polity and Ashoka's dhamma policy in ancient history. the Topra and Meerut pillars, later moved to Delhi by Firuz Shah Tughlaq
• Minor Pillar Edicts: Minor Pillar Edicts are the shorter Ashokan inscriptions engraved on pillars, distinct from the major pillar edicts: the Schism Edict (Sarnath, Sanchi, Allahabad-Kosam), the Queen's Edict, and the Rummindei and Nigali Sagar edicts. The Rummindei edict marks Lumbini as the Buddha's birthplace and records Ashoka's tax remission there. For UPSC, they are standard prelims material on Mauryan epigraphy and Ashoka's dhamma. Rummindei pillar edict at Lumbini
• Cave inscriptions: Cave inscriptions are texts carved on the walls of rock-cut caves, a major source for reconstructing ancient Indian history. They record royal donations, religious patronage, and political events, often in Brahmi or Kharosthi scripts, and date from the Mauryan period onward. Buddhist, Jain, and Ajivika caves carry many of them. They matter for UPSC as primary epigraphic sources for polity, religion, and art in ancient history. The Hathigumpha inscription of King Kharavela in Odisha, a 2nd-century BCE record of his reign and Jain patronage.
• Ajivika: Ajivika was a heterodox ascetic sect founded by Makkhali Gosala, a contemporary of the Buddha and Mahavira, teaching Niyati (absolute determinism): all events, including liberation, follow a fixed cosmic order, so human effort cannot change outcomes. It attracted royal patronage in the Mauryan age before declining. For UPSC ancient-history questions, it illustrates the sixth-century BCE ferment of materialist and fatalist schools alongside Buddhism and Jainism. Ashoka's dedications of the Barabar rock-cut caves to Ajivika monks (3rd century BCE)
• Prakrit: Prakrit refers to the group of Middle Indo-Aryan vernacular languages, including Pali, Ardhamagadhi, Shauraseni, and Maharashtri, spoken and written roughly from the sixth century BCE to the first millennium CE. Ashokan edicts, the Jain canon, and early Sanskrit drama used Prakrits. It matters for UPSC as the linguistic bridge between Sanskrit and modern Indo-Aryan languages, and as the medium of early Buddhist and Jain literature. Ashoka's edicts were inscribed in Prakrit using Brahmi script so ordinary people could understand them.
• Brahmi: Brahmi is the ancient Indian script in which Ashoka's third-century BCE edicts were inscribed, written left to right and ancestral to nearly all later Indian scripts including Devanagari. Its decipherment by James Prinsep in 1837 unlocked Mauryan history. For UPSC, Brahmi versus Kharosthi (used in the northwest, written right to left) is a classic script-and-inscription question. the Major Rock Edicts of Ashoka at Girnar and Dhauli, engraved in Brahmi Prakrit
• Kharosthi: Kharosthi was a script written from right to left, derived from Aramaic, used in Gandhara and the northwestern subcontinent from about the third century BCE to the fourth century CE. It appears in Ashokan edicts at Shahbazgarhi and Mansehra, in Gandhari Buddhist manuscripts, and on Kushana coins. It matters for UPSC as evidence of cultural contact with the Achaemenid and Hellenistic worlds and of early Buddhist literary culture in the northwest. Ashoka used Kharosthi in his northwestern edicts so that local populations could read his dhamma proclamations.
• Greek and Aramaic: Greek and Aramaic are the two non-Indian languages in which some of Ashoka's edicts were issued in the empire's northwest, reflecting the region's Hellenistic and Achaemenid cultural inheritance. The Kandahar bilingual rock edict renders Ashoka's message in both languages. They matter for UPSC because they are primary evidence of the Mauryan empire's reach into the Hellenistic world and a favourite Prelims fact on Ashokan edicts and their languages. The Kandahar (Shar-i-Kuna) bilingual rock edict of Ashoka, inscribed in Greek and Aramaic in present-day Afghanistan.
• prashasti: A prashasti is a formal eulogy composed in ornate Sanskrit verse or prose to praise a king's genealogy, conquests, and virtues, usually engraved on stone pillars or copper plates. Court poets wrote them as royal propaganda, but historians mine them as datable evidence of political history. Prashastis are standard GS-1 (ancient India) source material. The Prayag Prashasti of Samudragupta, composed by his court poet Harisena on the Allahabad pillar.
• Allahabad pillar inscription: The Allahabad pillar inscription is the Prayag Prashasti, a Sanskrit eulogy of the Gupta emperor Samudragupta composed by his court poet Harisena and engraved on the Ashokan pillar at Allahabad. It records his military campaigns across northern and southern India and names the rulers he defeated or subjugated. It is the single most important source for Samudragupta's reign and a staple of UPSC ancient history. Its account of the Dakshinapatha expedition, naming twelve southern kings, establishes the reach of Gupta influence.
• Prayag Prashasti: Prayag Prashasti is the Allahabad pillar inscription that eulogizes the Gupta emperor Samudragupta, composed in Sanskrit by his court poet Harisena. It records his conquests across Aryavarta and Dakshinapatha, his patronage of learning and his Ashvamedha sacrifice, making it the single most important source for Gupta political history. It matters for UPSC because inscriptions as historical sources, and this prashasti in particular, are among the most-tested ancient-history topics. Harisena, court poet of Samudragupta
• Harisena: Harisena was the court poet and minister of the Gupta emperor Samudragupta (4th century CE). He composed the Prayaga Prashasti, the celebrated Allahabad pillar inscription in Sanskrit that lists Samudragupta's conquests and political titles. It matters for UPSC because the prashasti is the single most important literary source for reconstructing Gupta political history and a favourite prelims question. The phrase describing Samudragupta as the 'Napoleon of India' in historiography traces to V.A. Smith's reading of Harisena's Prayaga Prashasti account of his campaigns.
• Samudragupta's: Samudragupta is the Gupta emperor (c. 335-375 CE), son of Chandragupta I, celebrated in the Allahabad Pillar Inscription of Harisena as a conqueror whose campaigns spanned the Gangetic plain, the Deccan and the far south. Called the Indian Napoleon, he was also a patron of arts and music who issued splendid gold coins. The Gupta age is core ancient history for both prelims and mains. The Prayaga Prashasti composed by his court poet Harisena.
• Aihole inscription: The Aihole inscription is a seventh-century prashasti (eulogy) composed by the court poet Ravikirti and engraved at the Meguti Jain temple in Aihole, Karnataka. Dated to Saka 556 (634 to 635 CE), it recounts the victories of the Chalukya king Pulakeshin II, including his defeat of Harshavardhana on the banks of the Narmada. For UPSC, it is a key primary source for the early history of the Deccan. The inscription's record of Harshavardhana's defeat in battle around 618 to 619 CE is the main evidence that the Narmada became the boundary between the Vardhana north and Pulakeshin II's Deccan.
• Ravikirti: Ravikirti was the court poet of the Chalukya king Pulakeshin II who composed the famous Aihole inscription of 634 CE. The prashasti eulogises Pulakeshin's victories, including his defeat of Harshavardhana on the Narmada, and describes the Chalukya capital Vatapi. A Jain scholar, Ravikirti also built a Jain temple at Aihole. He matters for UPSC because his inscription is the principal contemporary source for early Chalukya history and the Harsha-Pulakeshin conflict. Ravikirti's claim that Harsha's 'merry-making' ended at the Narmada is the key evidence of Pulakeshin's northern victory.
• Pulakesin II: Pulakesin II was the greatest Chalukya king of Vatapi, ruling circa 610 to 642 CE. He checked Harshavardhana's southward expansion by defeating him on the Narmada, extended Chalukya power across the Deccan, and exchanged embassies with the Persian king Khusrau II. His court poet Ravikirti's Aihole inscription is the key source for his reign. For UPSC, he anchors ancient-history questions on Deccan polity and Harsha's contemporaries. Aihole inscription of Ravikirti
• Parameswara: Paramesvara was the imperial title borne by Pulakesin II of the Chalukyas, celebrated in Ravikirti's Aihole inscription. The title, meaning supreme lord, marks the Chalukya claim to paramount power in the Deccan, and for UPSC it is the exam-favourite example of royal titulature recorded in inscriptions. Ravikirti's Aihole prashasti hails Pulakesin II as Paramesvara after victories that included checking Harshavardhana on the Narmada.
• Sanskrit and Old Kannada script: The phrase refers to inscriptions composed in the Sanskrit language but written in the Old Kannada script, of which the Aihole prashasti of Pulakesin II, composed by his court poet Ravikirti, is the classic example. It shows Sanskrit as the prestige language of the court even where the local script was Kannada. Such epigraphic details are asked in prelims art-and-culture questions. Ravikirti's Aihole inscription praising Pulakesin II, composed in Sanskrit and written in the Old Kannada script.
• Hathigumpha inscription: The Hathigumpha inscription is a 17-line Prakrit inscription in Brahmi script carved in the Udayagiri-Khandagiri caves near Bhubaneswar, recording the achievements of the Kalinga king Kharavela of the Chedi dynasty (1st century BCE). It describes his military campaigns, public works and patronage of Jainism. It matters for UPSC because it is a key primary source for ancient Odisha's history and a recurring art-and-culture prelims topic. Kharavela's boast in the inscription that he retrieved the Kalinga Jina image carried away by a Nanda king is cited as evidence of early Jain royal patronage.
• Kharavela: Kharavela was a king of Kalinga (modern Odisha) in the second to first century BCE, known chiefly from the Hathigumpha inscription at Udayagiri near Bhubaneswar. A Jain patron and military commander, he raided deep into the Deccan and the north and claimed to have recovered Kalinga's treasures. He matters for UPSC because his inscription is a rare early source for eastern Indian political history and for the antiquity of Jainism in Odisha. The Hathigumpha inscription records Kharavela's campaigns and his patronage of Jain monks in the Udayagiri and Khandagiri caves.
• Mehrauli Iron Pillar: The Mehrauli Iron Pillar is a nearly seven-metre iron column in Delhi's Qutb complex, bearing a Sanskrit inscription of a king named Chandra, identified with the Gupta emperor Chandragupta II of the fourth to fifth century CE. Forged from high-phosphorus wrought iron, it has famously resisted rust for sixteen centuries. It matters for UPSC as proof of advanced ancient Indian metallurgy and as an epigraphic source for Gupta history. Metallurgists cite the pillar's corrosion resistance as evidence of sophisticated iron-forging techniques in Gupta India.
• Chandra: Chandra here is the king named in the Mehrauli iron pillar inscription, identified with the Gupta emperor Chandragupta II Vikramaditya of the fourth to fifth century CE. His rust-free pillar in Delhi's Qutb complex is proof of advanced ancient Indian metallurgy and a key epigraphic source for Gupta history. The pillar praises Chandra's victories, and scholars identify him with Chandragupta II Vikramaditya of the Gupta golden age.
• Junagadh rock inscription: The Junagadh rock inscription is a rock face at Girnar in Gujarat carrying three layers of Indian epigraphy: Ashoka's fourteen major rock edicts in Prakrit and Brahmi, Rudradaman I's Sanskrit prashasti of about 150 CE recording the repair of the Sudarshana lake, and a later Gupta inscription of Skandagupta. For UPSC, Rudradaman's record is the first long Sanskrit royal inscription, marking the shift from Prakrit to Sanskrit in courtly epigraphy. Rudradaman I's account of the Sudarshana lake being repaired by his governor Suvisakha
• Rudradaman: Rudradaman is Rudradaman I (reigned c. 130-150 CE), the greatest Saka ruler of the Western Kshatrapas, famed for the Junagadh rock inscription of c. 150 CE in chaste Sanskrit. It records his repair of the Sudarshana Lake from his own treasury, levying no extra taxes, and his defeat of the Satavahanas. He matters for UPSC because the inscription is a classic prelims source on ancient Indian polity, water management and Sanskrit epigraphy. Junagadh rock inscription (c. 150 CE)
• Sanskrit: Sanskrit is the classical literary and liturgical language of ancient India, the vehicle of the Vedas, Upanishads, epics and the works of Panini, Kalidasa and Aryabhata. Its grammar was fixed by Panini's Ashtadhyayi (c. 4th century BCE), and it remains one of India's 22 scheduled languages and the root of most north Indian tongues. Language and literature are recurring prelims themes. Panini's Ashtadhyayi, the foundational Sanskrit grammar.
• The Mandasor pillar inscription: The Mandasor pillar inscription is the record of Yasodharman's victories engraved on twin monolithic pillars at Sondani near Mandsaur in Madhya Pradesh. The Aulikara king claims dominion from the Brahmaputra to the western ocean and boasts that the Huna king Mihirakula paid him homage. It matters for UPSC as the principal epigraphic evidence for the defeat of the Hunas and the post-Gupta political order. the Sondani victory pillars of Yasodharman, dated to 532 CE
• Yasodharman: Yasodharman was the early sixth-century ruler of Malwa whose Mandasor pillar inscription records his decisive victory over the Huna chief Mihirakula around 528 CE, checking the Huna advance into central India. Styling himself with imperial titles, he briefly dominated much of northern India. For UPSC ancient history, he is the key figure in the fall of Huna power and the political fragmentation between the Guptas and Harsha. Mandasor pillar inscription (c. 532 CE)
• The Bhitari pillar inscription: The Bhitari pillar inscription is the Sanskrit record of the Gupta emperor Skandagupta (reigned c. 455-467 CE), engraved on a pillar at Bhitari in present-day Ghazipur, Uttar Pradesh. In nineteen lines it narrates his genealogy and celebrates his victories over the Pushyamitras and, crucially, the Hunas, making it the key epigraphic source for the Gupta-Huna wars. For UPSC, it is a classic GS-1 ancient history prelims fact on Gupta epigraphy. Skandagupta's checking of the Huna advance on the Indus, c. 458 CE
• Skandagupta: Skandagupta is the Gupta emperor who ruled circa 455 to 467 CE, succeeding Kumaragupta I at a moment of Hun (Huna) invasions from the northwest. He repelled the Hunas, an achievement recorded in the Bhitari pillar inscription, and his Junagadh inscription records the repair of the Sudarshana Lake dam. For UPSC his reign is studied as the last effective Gupta resistance before the empire's decline, illustrating how inscriptions serve as historical sources. The Junagadh rock inscription recording his repair of the Sudarshana Lake embankment.

Mandasor and Bhitari: the Huna wars in stone

The Mandasor pillar inscription of Yasodharman of Malwa celebrates his defeat of the Huna chief Mihirakula in the early 6th century CE. The Bhitari pillar inscription of Skandagupta records the Gupta emperor's own wars against the Hunas. They matter because the Huna invasions that ended Gupta power are known largely through these two victory inscriptions: the losers' boast and the winners' reply, both in stone.
