How do you date a 2,000-year-old book that doesn't say when it was written? You look at what it talks about. The Arthashastra mentions China silk — china-patta. The word "China" only entered use after the Chin dynasty started in 221 BCE. So the text is at least that recent. The Arthashastra mentions red coral from Alexandria — a trade that exploded in the first century CE when Greek sailors learned to use the monsoon winds. So the text is at least that recent. The Arthashastra uses Parasamudra for Sri Lanka — a name first attested in Greek sources around 100 CE. The Arthashastra describes silver and copper coins but not gold coins — gold coins arrived with the Guptas in response to Roman gold debasement in the 200s CE. Pile up the trade-goods evidence and you get a date around 150 CE. Maybe.
The text is traditionally attributed to Kautilya, also called Chanakya, who served as minister to Chandragupta Maurya around 321 BCE. The traditional date is 400 years older than what the trade goods suggest.
So which is it? Mauryan or post-Mauryan? The scholars don't agree.
R.P. Kangle produced the critical edition of the Arthashastra in 1960. Trautmann calls his knowledge of the text "unsurpassed."1 Kangle favored the Mauryan date — the traditional Chanakya attribution. He thought the trade-goods references could be explained by post-Mauryan editorial revision rather than original composition date. The text we have, in his view, is the work of an actual minister to Chandragupta, with later layers added.
S.R. Goyal disagreed. Trautmann describes Goyal as "one of India's pre-eminent historians of the ancient period."1 Goyal made a close comparison of the Arthashastra with the account of the Mauryan Empire by the Greek ambassador Megasthenes — a contemporary witness to the Mauryan court. The two texts didn't match. Megasthenes describes specific institutions and practices that the Arthashastra doesn't mention. The Arthashastra describes specific institutions and practices that Megasthenes doesn't mention. Goyal concluded that the Arthashastra cannot be from the Mauryan period — if it were, it would describe the Mauryan world Megasthenes saw, and it doesn't.
Both scholars are looking at the same evidence and reaching opposite conclusions. The evidence is genuinely ambiguous.
The dating shifts how the text should be read. If it's Mauryan, it's the product of a specific minister at a specific court advising a specific king during the formation of the first major Indian empire. The text reflects the practical concerns of that empire's ruling elite. If it's post-Mauryan (150 CE), it's the product of a later scholar synthesizing the arthashastra tradition centuries after the Mauryans had passed. The text reflects what later thinkers thought ancient kingship had been or should have been.
The two readings produce different texts. The Mauryan reading gives you a primary historical document. The post-Mauryan reading gives you a synthesis with significant historical distance from the kingdoms it describes. Both are valuable. They're not the same kind of valuable.
Trautmann notes that "most agree that it is the product of a tradition containing different schools of thought and notable teachers, and that some elements of the tradition go back a long way, even before the Mauryan Empire."1 The Arthashastra is the surviving end-point of a longer tradition. Earlier elements (the four-instruments doctrine of sama/dana/bheda/danda, for instance) likely predate Kautilya by centuries. Later elements (the trade-goods references) likely postdate him.
This is partly why both Kangle and Goyal can be right about parts of the text. The Mauryan layer exists. The post-Mauryan layer exists. The compiled text we have shows both. The disagreement is about which layer is dominant — whether the synthesis happened in the Mauryan period (with later editorial additions) or in the post-Mauryan period (drawing on Mauryan and earlier material).
The trade-goods dating evidence is at lines 499-507 of the source.1 The Kangle/Goyal disagreement is at line 509. The compromise framing about a multi-layer tradition is at line 511.
The evidence really is ambiguous. The trade-goods clock pushes post-Mauryan. The traditional attribution pushes Mauryan. The internal stylistic and structural features of the text don't decisively favor one over the other. Both scholarly positions are well-grounded. The disagreement persists because the evidence doesn't resolve it.
[Single source — Trautmann/Kangle. Olivelle 2013 priority second source for verification. The trade-goods dating evidence is attested in Trautmann's analysis. The Kangle/Goyal disagreement is named in the source. Trautmann himself favors the post-Mauryan date but acknowledges the contestation.]
Most ancient texts have similar attribution problems. The methods used to investigate them shape what we think we know about the past.
History: Textual dating by content reference is the standard method for ancient texts whose composition date isn't recorded. The Arthashastra's case is unusual mainly because the trade-goods references are unusually specific (China silk, Roman coral, Greek sea names). Most ancient texts don't have such precise content anchors. The technique applies broadly — any text that mentions a place name, a trade good, a coin, or a foreign people whose appearance in Indian history is known can be dated by the appearance. The Arthashastra is therefore both a case study in the technique and a beneficiary of it. Modern textual scholarship in other traditions (biblical studies, classical studies, Buddhist studies) uses analogous methods.
Cross-Domain: The dating uncertainty has implications for how the text gets used. If you're trying to extract Mauryan-era political-economic intelligence, you need the Mauryan reading. If you're studying the long-tail synthesis of arthashastra thought, you need the post-Mauryan reading. The two uses are not contradictory but they require different sourcing assumptions, and a careful reader keeps both possibilities live rather than committing to one.
The Sharpest Implication
Most ancient texts have similar attribution and dating problems. The methods used to investigate them — content analysis, comparison with contemporary sources, internal stylistic analysis — shape what we think we know about the past. The Arthashastra's case is unusually visible because Trautmann names the disagreement explicitly. Most ancient texts have analogous unresolved disagreements that get less surface in their popular treatments. The implication: every claim about what an ancient text says about its period has a layer of dating uncertainty underneath that the casual reader rarely sees.
