கடல் வழி முடிச்சுThe Oceanic Node
Five node-sites are indexed here — each with a peer-reviewed excavation report or corpus study. Every one contains Tamil-Brāhmī inscriptions, Śaiva sanctuary architecture, or both. The Sri Lankan northern harbours (Mannār, Kāyts, Jaffna, Trincomalee) sit on the same lattice, not off it.
An open-access GIS layer overlaying the five sites plus the Sri Lankan northern harbours plus the Sangam-corpus port references (Musiri, Kāvirippūmpaṭṭinam, Korkai, Māntai). Nilaiththanmai target: the node argument as a visible map that any adjudicator can query.
Berenike & Quseir al-Qadim · Red Sea (2nd c. BCE – 2nd c. CE)
Berenike (modern Egyptian Red-Sea coast), excavated by Sidebotham (Delaware) and colleagues, has yielded Tamil-Brāhmī inscribed potsherds — the most-cited being a graffito reading 'Kōrraṉ, a chieftain' (or similar) — dated to the 1st–2nd c. CE [01]. Quseir al-Qadim (ancient Myos Hormos) has yielded further Tamil-Brāhmī pottery [02]. These are the western anchors of the network.
Pattanam / Muziris · Kerala (1st c. BCE – 5th c. CE)
Excavations by the Kerala Council for Historical Research (KCHR) at Pattanam, identified with ancient Muziris of the Periplus and Roman itineraria, recovered Mediterranean amphorae alongside Tamil-Brāhmī graffiti and Chera-period Indian-Ocean trade material [03]. Pattanam is where the western and eastern arms of the lattice meet.
Khuan Luk Pat · Thailand (2nd–4th c. CE)
The Khuan Luk Pat site on the Andaman coast of southern Thailand yielded a Tamil-Brāhmī inscribed touchstone reading 'perumpaṭaṉ kal' (touchstone of the great goldsmith) — reported by Boriphan Ngampradit, corroborated by Iravatham Mahadevan [04]. This is the eastward anchor.
Quanzhou (Zayton) · Fujian, China (13th c. CE)
The Song–Yuan period Chinese imperial port of Quanzhou hosted a Tamil-Śaiva sanctuary. A bilingual Tamil–Chinese inscription dated 1281 CE records the founding of a temple by a Tamil merchant community under imperial authorisation, and Tamil-Śaiva sculptural fragments (Nataraja, Umā-Maheśvara) are preserved in the Quanzhou Maritime Museum [05][06]. Peer-reviewed by Guy (Met Museum), Karashima and Subbarayalu (Toyo Bunko / Tokyo).
Barus / Lobu Tua · Sumatra (11th–13th c. CE)
The Lobu Tua site in northern Sumatra yielded a Tamil-language inscription of the Ayyāvoḷe 500 merchant-guild dated 1088 CE — establishing a formal Tamil merchant corporation on the Sumatran coast contemporary with the Chola thalassocracy [07]. Karashima and Subbarayalu published the corpus.
Reading the lattice
Sri Lanka's northern harbours — Māntai/Mahātittha, Mannār, Kāyts, Trincomalee — sit on this lattice, not off it. Māntai was the western turnstile between the Bay of Bengal and the Arabian Sea. Any reading that treats them as peripheral is reading the map upside down.
The programme has an inscribed 'Maritime Silk Road' thematic frame. Tamil-node inclusion is procedurally addressable.
Cultural-route inscription (Qhapaq Ñan precedent) is a filing pathway for network arguments that no single site captures.

- · Does not claim any of these ports was 'Tamil territory'. They were multi-ethnic emporia where Tamil-speaking merchants had formal presence.
- · Does not claim the Chola thalassocracy is a template for anything in the present. The Chola military expeditions to Śrīvijaya (1017, 1025 CE) are treated as fact, not as model.
- · Does not conflate Tamil-Brāhmī with 'Tamil ethnic presence' — it names literate Tamil-speaking presence.
- · Does not treat the Sangam corpus as historically transparent — treats it as literature with corroborated port-name geography.
