Sources

Everything in this atlas can be traced to a text or a reference. Here is what we used, how we cite it, and where the map’s positions come from.

The text

The Mahābhārata, Critical Edition. Edited by V. S. Sukthankar, S. K. Belvalkar, P. L. Vaidya and others. Bhandarkar Oriental Research Institute, Pune, 1933–1966, 19 volumes. The scholarly text that this atlas follows. Chapters are cited as parva.chapter, so 2.43 is the Sabha Parva, chapter 43.
Bibek Debroy, The Mahabharata. Penguin India, 2010–2014, 10 volumes. The English translation of the Critical Edition used for every summary here. For the events in this version of the atlas: the Sabha Parva and the opening of the Aranyaka Parva are in volume 2, the rest of the Aranyaka Parva in volume 3, the Virata Parva and the first part of the Udyoga Parva in volume 4, and the rest of the Udyoga Parva and the Bhishma Parva, including the Bhagavad Gita, in volume 5. Check each volume’s table of contents for exact section numbers.
J. A. B. van Buitenen, The Mahābhārata. University of Chicago Press, 1973–1978, 3 volumes (Books 1–5). A second translation of the Critical Edition, used to cross-check readings from the Adi through the Udyoga Parva.
Kisari Mohan Ganguli, The Mahabharata of Krishna-Dwaipayana Vyasa. 1883–1896. The public-domain complete translation. It follows the longer vulgate text, not the Critical Edition, so it is used only to identify passages that the atlas labels as traditional.

Parvas covered so far: Adi Parva, Sabha Parva, Aranyaka Parva, Virata Parva, Udyoga Parva, Bhishma Parva. Every event panel ends with the exact chapter ranges it draws on.

How statements are labelled

Critical Edition the Critical Edition text contains this.
Traditional found in later manuscripts, regional versions, or widely repeated retellings, but not in the Critical Edition.
Adaptation a choice made by a film, television series, comic or novel.

Where the places come from

No place in the epic has a surveyed location. Positions on the map follow these references, and every marker carries a confidence label.

Joseph E. Schwartzberg (ed.), A Historical Atlas of South Asia. University of Chicago Press, 1978; second impression, Oxford University Press, 1992. The standard scholarly atlas; its plates on the epic and Vedic periods are the main guide for kingdom positions.
Bimala Churn Law, Historical Geography of Ancient India. Société Asiatique de Paris, 1954. Identifications of rivers, cities and peoples named in the text.
Nundo Lal Dey, The Geographical Dictionary of Ancient and Mediaeval India. Luzac, 1927. Older but still useful for traditional identifications of place names.
B. B. Lal, “Excavation at Hastināpura and other explorations in the Upper Gaṅgā and Sutlej basins”. Ancient India 10–11, 1954–1955. The excavation that links modern Hastinapur to an early settlement.
Natural Earth (naturalearthdata.com), public domain. The present-day coastline, rivers and lakes drawn under the kingdoms, at 1:50m scale, simplified.

The Sarasvati, central to the story, is drawn as the seasonal Ghaggar that Natural Earth records today; ancient river courses differed. Kingdoms are deliberately wobbly blobs centred on a plausible position, never borders.

Secondary references used for the character cards

Vyasa Online encyclopedia (vyasaonline.com). Entry-by-entry summaries of the characters with parva references, used to cross-check the physical descriptions and iconography on the cards. A compilation rather than a translation; where it and the text differ, the text wins.
Nitin Rastogi, “Flags and their meanings in Mahabharata” (nitswe.blogspot.com, 2018). A compiled list of the warriors’ chariot standards, used to check the crests on the cards against the Bhishma and Drona Parvas.

Words to know

The short definitions that appear in event panels, collected in one place.

Parva parvan: One of the eighteen big books of the Mahabharata. Each parva is divided into chapters, so 2.43 means the Sabha Parva, chapter 43.
Critical Edition: The version of the Mahabharata that scholars in Pune assembled between 1933 and 1966 by comparing hundreds of old manuscripts and keeping only what they share. This atlas follows it.
Rajasuya rājasūya: A huge royal ceremony. A king who completes it is recognised as a king of kings by all the rulers who attend.
Sabha sabhā: A royal assembly hall, and the gathering of nobles held inside it.
Dice game dyūta: A game of dice played for stakes. A king was expected to accept a challenge to play, which is why Yudhishthira cannot refuse.
Dharma dharma: The right way to act: duty, law and justice all at once. Characters in the epic argue constantly about what dharma demands.
Forest exile vanavāsa: Living in the forest as an exile, wearing deerskin and bark, far from cities and thrones.
Year in hiding ajñātavāsa: The thirteenth year of exile, spent in disguise in a town. If the Pandavas had been recognised, the twelve-year exile would have started all over again.

Envoy dūta: A messenger sent between rulers to negotiate. Envoys were protected and not supposed to be harmed, which is why Duryodhana's plan to seize Krishna is so shocking.

Commander-in-chief senāpati: The general in overall command of an army.
Atiratha atiratha: A warrior so skilled that he counts as equal to many chariot-fighters at once. Bhishma grades the warriors on both sides this way.

House of lac jatugṛha: A house built of lac, resin, hemp and ghee so that it would burn in an instant. Duryodhana had one built at Varanavata to kill the Pandavas.
Vow pratijñā: A solemn promise that could not be taken back. Bhishma's vow never to marry or rule is the most famous; Bhima's vows at the dice game are the most terrible.
Apsara apsarā: A celestial nymph of Indra's heaven. Urvashi curses Arjuna when he refuses her.
