Where the poems stood.
Two thousand years ago, four hundred and seventy poets named the hills, ports and rivers of the Tamil country. This atlas puts every one of those names back on the ground, and tells you how sure we are.
வடவேங்கடம் தென்குமரி ஆயிடைத் தமிழ்கூறு நல்லுலகம்From Vēṅkaṭam in the north to Kumari in the south, the good world that speaks Tamil. Preface to the Tolkāppiyam.
Places
Every toponym as a record: names, candidate locations, poems that attest it, and the scholar behind each claim. பாடல்Poems

Six poems, read by place.
The full corpus is 2,381 poems. This preview loads six that name places, with every line in Tamil and ISO 15919 and every place name linked to the map.
A code for feeling, drawn on land.
Each akam poem is set in one of five tiṇai. Each tiṇai bundles a terrain, an hour, a season, a god and a mood. The Tolkāppiyam itself says pālai has no landscape of its own: it is kuṟiñci or mullai parched in summer. The atlas therefore treats tiṇai as a filter on poems and never draws it as a region.
How sure are we?
Every dot on this map is a claim. This page says whose claim, on what evidence, and how we draw doubt.
Status of this draft
This is release 0.1, a draft. Every identification is provisional. No external scholar has yet reviewed the gazetteer, the poem summaries or the transliterations. Before the first reviewed release, an editorial panel of Tamil literature scholars, archaeologists and a cartographer will read every record, and each identification will carry the reviewer's name and date. Until then, treat each dot as a hypothesis with a source, not a finding. Corrections are invited on every place page.
Origins and acknowledgements
The idea for this atlas came from a conversation with Dr. M. Rajendran, President of the Tamil Valarchi Kazhagam (the Tamil Development Academy, founded in 1946) and former Vice-Chancellor of Tamil University, Thanjavur, at the Global Tamil Research Conference in Toronto in October 2026. He asked why Tamil had no atlas of its oldest poetry when other literatures have theirs. The identifications, summaries and errors in this draft are the editors' responsibility, not his.

Geography from Natural Earth. Tamil text from U. V. Cāminātaiyar's editions through Project Madurai. Shoreline studies by the National Institute of Oceanography, Goa; Gaur and Sundaresh; Dayalan; Gurukkal and Whittaker. Place identifications after Pleiades, the Barrington Atlas and the scholars named on each place page.
Three levels of certainty
| Level | Meaning | Symbol |
|---|---|---|
| Certain | The name is preserved on the ground, or excavation confirms the site, and no serious alternative exists. | Solid dot |
| Less certain | Most scholars agree, but the evidence is indirect, or a credible alternative exists. | Hollow dot |
| Uncertain | A proposal with weak support, or one of several competing candidates. | Dashed dot |
| Unlocated | Attested in the poems. No identification has been proposed. | No dot. Listed in the rail. |
| Excavated site | An excavated site that the poems do not name, shown as an anchor for the archaeology. Each carries its excavators and a dated range. | Grey square. Dashed square if earlier than the poems. |
| Hill | A hill or mountain, located by name preservation. | Triangle, with the same solid, hollow or dashed rule. |
A faint ring around a dot shows positional precision in metres. Two dots joined by a dotted line are competing candidates for one place. We do not compute a midpoint between them. The map is an equirectangular projection true at 11°N; a scale bar sits at the lower left and is exact at that latitude.
What the coast looked like
No digital palaeocoastline exists for South India. The hatched bands near Koṟkai, Pukār and Muciṟi span the published range of the ancient shoreline, drawn from site-specific studies: Dayalan (2019) and Sundaresh et al. (2014) for the Tāmiraparaṇi delta, the NIO Goa surveys (1995) and Gaur and Sundaresh (2006) for Pukār, and Gurukkal and Whittaker (2001) for the Periyār mouth. Each carries its own confidence. Everything else is the modern coast from Natural Earth.
Tiṇai
Tiṇai labels in the anthologies come from the arrangement or from medieval colophons, not from the poets. We record where each label comes from. We never draw tiṇai as polygons, following Selby (2008) and Haricharan and Keerthi (2014).
Time
No Sangam poem carries a date. We store date ranges with the scholar who proposed them and the basis (a synchronism, palaeography, language). The map has no year slider in this preview because a slider would invent precision the evidence does not have.
Texts and rights
Tamil text follows U. V. Cāminātaiyar's editions through Project Madurai, with the poem numbering every scholar uses. Transliteration is ISO 15919. Summaries are our own prose. We link to published translations and do not copy them.
Kumari Kandam
The poems speak of a Pāṇṭiya land taken by the sea and of a river Kumari. The continent of Kumari Kandam is a nineteenth-century idea grafted onto those lines. The atlas maps Kumari as the cape and lists the lost river as an unlocated name. See Sumathi Ramaswamy, The Lost Land of Lemuria (2004).

Every place page has a link that opens a pre-filled issue. Corrections are reviewed by two named editors and appear in the next numbered release with a changelog entry.
