How we know: sources for Mauryan history

Detail

The source stack — five kinds of evidence

Historians build Mauryan history from five bundles of evidence. No single one is enough. Each has gaps, so they are read against one another.

• Archaeological finds, especially sculpture. Stone pillars, capitals, pottery and city remains. These show craft skill and state spending, but they carry no names or dates by themselves.
• Megasthenes' fragments. Megasthenes was a Greek ambassador sent by King Seleucus I to the court of Chandragupta. He wrote a four-book work called Indica [5].
• The original book is lost. We only have pieces of it quoted by later Greek writers — Strabo, Diodorus and Arrian [5].
• So we read Megasthenes second-hand: a Greek visitor's account, copied out centuries later by other Greeks.

• The surviving fragments were collected by Dr Schwanbeck and translated into English by J.W. McCrindle as Ancient India as described by Megasthenês and Arrian [8].

• The Arthashastra. A manual on statecraft — how to run a kingdom, collect taxes and manage land. Parts of it were probably composed by Kautilya, also called Chanakya, traditionally the minister of Chandragupta [6].

• It is a manual of theory, not a diary of events. It says what a ruler should do, not always what Mauryan rulers did.

• The text pulls together almost everything written in India up to its time on property, wealth and worldly success [6]. English editions of Kautiliya Arthasastra are available through the Government of India's Indian Culture portal [7].

• Later literature. Buddhist, Jaina and Puranic works, plus Sanskrit texts. These were written down long after the Mauryas fell, so each tradition shapes the story to fit its own faith.

• The inscriptions of Ashoka, cut on rocks and pillars. These are regarded as the most valuable source of all.

Why Ashoka's inscriptions rank highest

• Ashoka was the first ruler to inscribe messages to his subjects and officials on stone. Before him, rulers did not speak to their people this way.
• The words are the ruler's own words, from his own time — not a later writer's memory of him.
• The stone does not rot, unlike palm-leaf manuscripts. What survives has survived unchanged.
• One well-known group is the Ashokan rock edicts at Junagadh (Girnar), Gujarat, a protected Archaeological Survey of India site [4].
• Ashoka's reign is dated to roughly c. 265–238 BCE [3].

The Sohagaura copper plate

• Found at Sohgaura, Uttar Pradesh; dated 4th–3rd century BCE.
• One of India's earliest known administrative records.
• Written in Prakrit, in Brahmi script.
• Believed to have been issued under Chandragupta.
• Its content: it records a granary set up as a precaution against famines — a storehouse of grain kept ready for years when crops failed.
• Why it matters: it is proof that a state was already planning ahead for hunger, and writing that plan down on metal, at the very start of the empire.

Epigraphy: how the edicts were made readable again

Epigraphy means the study of inscriptions. For centuries nobody in India or Europe could read Ashoka's stones — the scripts had been forgotten.

• James Prinsep (born 20 August 1799, Essex, England; died 22 April 1840, London) was an East India Company mint officer in India [2].
• He deciphered Brahmi in 1838 and Kharosthi during the 1830s. Britannica records him as the first European scholar to read Ashoka's edicts, with the work done across 1837–1838 [2][3].
• Before this, Ashoka was almost unknown except in the Buddhist chronicles of Sri Lanka and northern Buddhist writings [3]. The decipherment turned a legend into a documented emperor.

Note: the scaffold dates the Brahmi breakthrough to 1838; Britannica mentions both 1837 and 1838 for the decipherment of the edicts [3]. Treat 1838 as the exam answer.

How Brahmi was cracked — step by step

• Scholars worked backwards from Bengali and Devanagari manuscripts, comparing later letter shapes with the older ones on the stone.
• They had made a wrong assumption first: they thought the earliest inscriptions must be in Sanskrit. They were not. They were in Prakrit, the everyday spoken language.
• Once the language was right, the letters fell into place.
• Brahmi appears as a fully formed writing system by the 3rd century BCE, and its most famous use is on Ashoka's rock edicts [9].

How Kharosthi was cracked

• Through Indo-Greek coins. These coins carried a king's name in two scripts — Greek and Kharosthi — side by side (for example, Apollodotus).
• A name already readable in Greek gave the sound value of each Kharosthi letter. This is a bilingual key, the same trick used on the Rosetta Stone.

"Piyadassi" and "Asoka" — one king or many?

• Most of the inscriptions name a king called "Piyadassi", which means "pleasant to behold". It is a title, not a birth name.
• Only a few inscriptions also use the name Asoka.
• Epigraphists concluded that one ruler issued them all. Their reasoning rested on four matching features:
• content — the same ideas and orders repeat;
• style — the same way of addressing people;
• language — the same Prakrit;
• palaeography — the same letter shapes (palaeography = the study of how handwriting and letter forms change over time).

Language and script map of the edicts

• Most Ashokan inscriptions: Prakrit language, Brahmi script.
• North-west India: some in Kharosthi script.
• Afghanistan: Aramaic and Greek — the languages people there actually used.
• The choice shows deliberate policy: the message was cut in whatever script and tongue the local population could follow.
• Prakrit was the popular language — the speech of ordinary people, not of priests and scholars.
• Brahmi is the mother of all regional scripts of India — Devanagari, Bengali, Tamil, Telugu and the rest all descend from it.

The limits of inscriptional evidence

Inscriptions are the best Mauryan source, but they must be questioned, not swallowed whole.

• They carry one point of view. An inscription shows the perspective of whoever paid for it — here, the king. The king's version of events is still a version.
• They record grand events, not daily life. Wars, gifts and royal orders get carved. What a farmer ate, or how a weaver worked, does not.
• Claims must be tested. Ashoka claims that earlier rulers had no arrangements for reporting — no system for officials to send news to the king. That may simply be a new ruler talking down those who came before him.
• What survives is only a fraction. Stone cracks, letters wear away, pillars fall and get reused. Technical problems mean much of what was inscribed is gone forever.
• Most people who walked past could not read. An order on a rock only works if someone reads it aloud, and only if the listeners understand it.
• Language reach was limited. The Prakrit of Pataliputra may not have been understood in far corners of the empire.
• The star example — the missing Kalinga edict. Ashoka's edict expressing anguish over the Kalinga war is absent exactly in conquered Odisha, the very land he says he felt sorry for. Instead, other edicts were put there.
• The lesson: reading edicts at face value fails. A king shows remorse to audiences far away, and shows authority to the people he has just defeated.
• What is missing from a site is evidence too.

Prelims Hooks

• James Prinsep, an East India Company mint officer, deciphered Brahmi in 1838 and Kharosthi in the 1830s [2].
• Prinsep was born 20 August 1799 and died 22 April 1840 [2].
• Kharosthi was cracked using Indo-Greek bilingual coins (Greek + Kharosthi), e.g. of Apollodotus.
• Most Ashokan edicts are in Prakrit language, Brahmi script; Kharosthi in the north-west; Aramaic and Greek in Afghanistan.
• The Sohagaura copper plate (Sohgaura, UP; 4th–3rd century BCE; Prakrit in Brahmi) records a granary against famine — an early administrative record linked to Chandragupta.
• Megasthenes' Indica had four books; the original is lost and survives only in quotations by Strabo, Diodorus and Arrian [5].
• Megasthenes was sent to Chandragupta's court by Seleucus I [5].
• The Arthashastra is attributed to Kautilya / Chanakya, traditionally Chandragupta's chief minister [6].
• Ashoka's inscriptions name a king "Piyadassi" = "pleasant to behold"; only a few also say Asoka.
• Brahmi, fully developed by the 3rd century BCE, is the mother of all regional Indian scripts [9].
• The Ashokan rock edicts at Junagadh (Girnar), Gujarat are an ASI-protected site [4].
• Before decipherment, Ashoka was known almost only from the Buddhist chronicles of Sri Lanka [3].

Mains Points

• No single source can carry Mauryan history; the gaps of one are filled by another. Megasthenes survives only as fragments quoted by later Greeks [5][8]; the Arthashastra states ideal policy rather than actual practice [6]; Buddhist, Jaina and Puranic texts are later and faith-shaped. Only Ashoka's inscriptions are contemporary and first-hand — which is exactly why they are ranked highest, and exactly why they must be cross-checked.
• Decipherment is itself a historical event. Prinsep's 1838 reading of Brahmi [2][3] converted a shadowy Buddhist legend into a documented emperor. It also shows how a wrong assumption blocks knowledge: scholars looked for Sanskrit and found nothing until they accepted the language was Prakrit. Method, not just evidence, decides what the past looks like.
• Inscriptions are royal speech, so absence is as telling as presence. The Kalinga-remorse edict is missing precisely in conquered Odisha. The empire tailored its message by audience — remorse for distant subjects, authority for the newly conquered. A GS-I answer should use this to argue that edicts are an instrument of rule, not a confession.
• State capacity appears very early. The Sohagaura plate's famine granary, and the choice to inscribe in Prakrit, Kharosthi, Aramaic and Greek, both point to an administration that planned ahead and adjusted its communication to local populations — even while most people who passed the stones could not read them.
