# Thronion
**Thronion** ([Ancient Greek](https://www.edgepedia.org/ancient-greek): Θρόνιον) is the name of two ancient Greek cities, one a polis of East Locris on the coast of central Greece and the other a Locrian-Euboean foundation on the Illyrian coast near modern Vlorë, Albania; a conical hill near Chaeroneia also bore a closely related name. The two cities are distinct in location and history, and both are known chiefly through literary references and a small number of inscriptions and coins.

## Thronion of East Locris
The Locrian Thronion appears in the earliest Greek literature. Homer's Catalogue of Ships names eight East Lokrian towns, Kynos, Opous, Kalliaros, Bessa, Skarphe, Augeiai, Tarphe, and Thronion, whose men followed Ajax son of Oïleus to the [Trojan War](https://www.edgepedia.org/trojan-war) in forty ships[4](https://www.ascsa.edu.gr/uploads/media/hesperia/148252.pdf). Theopompus (preserved in Harpocration) and, implicitly, [Thucydides](https://www.edgepedia.org/thucydides) also treat it as a Lokrian city[1](https://www.ancientportsantiques.com/wp-content/uploads/Documents/AUTHORS/Hansen%26Nielsen2004-LexiquePoleis.pdf).
**Political history.** The earliest recorded communal action of the city is the giving of hostages to the Athenians in 431 BC, at the start of the [Peloponnesian War](https://www.edgepedia.org/peloponnesian-war) (Thucydides 2.26.2)[1](https://www.ancientportsantiques.com/wp-content/uploads/Documents/AUTHORS/Hansen%26Nielsen2004-LexiquePoleis.pdf). In 426 BC an earthquake struck the town; the ancient account records about 850 deaths there[2](https://www.researchgate.net/profile/Klaus-Reicherter/publication/336668676_The_earthquake_and_tsunami_of_426_BC_in_Greece_observations_by_Thucydides_and_contextual_interpretations/links/60b74a83a6fdcc476bdf37c7/The-earthquake-and-tsunami-of-426-BC-in-Greece-observations-by-Thucydides-and-contextual-interpretations.pdf). A Delphic inscription records a border treaty between Skarpheia and Thronion, showing that the two cities' territories adjoined, and Strabo places Thronion 30 stadiums from Skarpheia[2](https://www.researchgate.net/profile/Klaus-Reicherter/publication/336668676_The_earthquake_and_tsunami_of_426_BC_in_Greece_observations_by_Thucydides_and_contextual_interpretations/links/60b74a83a6fdcc476bdf37c7/The-earthquake-and-tsunami-of-426-BC-in-Greece-observations-by-Thucydides-and-contextual-interpretations.pdf).
During the Third Sacred War (355–346 BC), fighting ran along the coast of Epiknemidian Lokris, and the Phokian general Onomarchos captured Thronion in 353 BC; his brother Phayllos subdued the remaining coastal cities, Alponos, Nikaia, Skarpheia, and Naryx, in 352 BC[3](https://ecommons.cornell.edu/bitstream/1813/13519/1/Nankov%2C%20Emil.pdf). Pseudo-Skylax's listing of Thronion in his Phokian chapter is read as a reflection of this Phokian destruction, but the city was in existence again in the 4th century BC, when it appears in Delphic manumission records (CID II 31.79, 32.37, 97.25)[1](https://www.ancientportsantiques.com/wp-content/uploads/Documents/AUTHORS/Hansen%26Nielsen2004-LexiquePoleis.pdf). Two Hellenistic decrees (IG IX.1 308–309) are the earliest preserved public enactments; one grants proxenia (ancient Greek honorary guest-friendship status for foreigners), isopoliteia, and other privileges to an Aitolian from Phytaios[1](https://www.ancientportsantiques.com/wp-content/uploads/Documents/AUTHORS/Hansen%26Nielsen2004-LexiquePoleis.pdf) • [5](https://epigraphy.packhum.org/text/42249).
**Coinage and territory.** In the first half of the 5th century BC Thronion struck silver obols on the Aiginetan standard, with a bearded male head on the obverse and a greave on the reverse bearing the legend ΘΡΟΝΙ, presumably a reference to Mount Knemis in Lokris[1](https://www.ancientportsantiques.com/wp-content/uploads/Documents/AUTHORS/Hansen%26Nielsen2004-LexiquePoleis.pdf). The city's territory is called ἡ τῶν Θρονιέων χώρα in Polybius 9.41.11, and Strabo records a harbor (limen) on its coast[1](https://www.ancientportsantiques.com/wp-content/uploads/Documents/AUTHORS/Hansen%26Nielsen2004-LexiquePoleis.pdf). The harbor towns of Opuntian Locris, including Thronion, are now semi- or fully submerged because of sea-level change[6](https://www.researchgate.net/publication/332504051_THE_ENHANCEMENT_OF_UNDERWATER_CULTURAL_HERITAGE_ASSETS_USING_AUGMENTED_REALITY_AR).
**Site.** The Digital Atlas of the Roman Empire places Thronion at Palaiokastro eis ta marmara in Greece, at 38.775841 N, 22.725727 E, with a temporal coverage from 750 BC to 30 BC and a Pleiades identifier of 541147[7](https://imperium.ahlfeldt.se/places/34373.html). A modern gazetteer entry locates the polity near Kenourgio in Central Greece with medium confidence[8](https://www.getgreece.com/ancient-greek-sites/thronion-east-lokris). The city was walled: Thucydides 12.44.1 and Diodorus 16.33.3 indicate walls, and by 1928 the course of the wall could no longer be traced in its entirety, though foundations of buildings and a temple were noted[1](https://www.ancientportsantiques.com/wp-content/uploads/Documents/AUTHORS/Hansen%26Nielsen2004-LexiquePoleis.pdf). In 1840 the ruins supplied stone material for the building of a factory[1](https://www.ancientportsantiques.com/wp-content/uploads/Documents/AUTHORS/Hansen%26Nielsen2004-LexiquePoleis.pdf).
## Thronion in Illyria
The second Thronion was a Greek city on the Illyrian coast in the bay of Vlorë, in Epirus near Amantia. Ancient tradition held that it was founded after the Trojan War by the Abantes of Euboea together with inhabitants of the Locrian Thronium[13](https://pausanias.symmachus.org/translation/5/22/4.html). R. L. Beaumont, who studied the chronology of Greek fortifications in Epirus and Illyria, judged the exact site uncertain within the limits Pausanias gives, weighing candidates that include the hill of Kánina southeast of Valona[9](https://ignca.gov.in/Asi_data/32975.pdf).
**Conquest by Apollonia.** Dating of the conquest varies among scholars: one account places it before 460 BC, another about 450 BC, and Beaumont dates the Apolloniate campaign between 450 and 435 BC[9](https://ignca.gov.in/Asi_data/32975.pdf). The Albanian archaeologist Neritan Ceka, of the Institute of Archaeology in Tirana, instead places a war in which Thronion of the Amantes opposed Apollonia around 470 BC, and treats Thronion as one of the protourban centers of southern Illyria rather than a fully formed city[10](https://www.persee.fr/doc/imea_1000-1000_1987_act_1_1_865?pageId=T1_136).
Underwater investigation at the site has detected a powerful defensive structure extending over 700 m parallel to the coast, interspersed with quadrangular towers[11](https://archaeopresspublishing.com/ojs/index.php/groma/article/download/1352/1067).
## Other namesakes
A conical hill near Chaeroneia in Boeotia, called Mount Thourion or Thurium Mons, is attested by Pausanias ([Description of Greece](https://www.edgepedia.org/description-of-greece) 9.40.7) and Plutarch (Life of Sulla 17.4); at its foot ran the river Morios and a temple of Apollo Thourios, and the hill was occupied by the enemy before the battle of 86 BC between Sulla and the forces of Mithridates under Taxilus[12](https://eostrata.com/place/thronion-pelop-33328?lang=ja). The form Thronion for this hill is placed by Ptolemy in his [Geography](https://www.edgepedia.org/geography) (3.14.16) within Achaea[12](https://eostrata.com/place/thronion-pelop-33328?lang=ja).
