Corbilo () was a trading city on the Loire river described by Polybius and Pytheas. Neither original sources have survived, but Pytheas is quoted by Polybius, who is in turn quoted by Strabo.
Strabo's (Geographia 4.2.2) is the only surviving text from antiquity to mention the city.
In the original ancient Greek: <blockquote>"ÃÂÃÂÃÂÃÂõÃÂÿý ôὲ ÃÂÿÃÂòùûὼý á½ÂÃÂá¿ÂÃÂÃÂõý á¼ÂüÃÂÃÂÃÂùÿý á¼ÂÃÂá½¶ ÃÂÿÃÂÃÂÃÂù ÃÂῶù ÃÂÿÃÂñüῶùõ ÃÂõÃÂá½¶ ἧàõἴÃÂ÷úõ àÿûÃÂòùÿÃÂõ üý÷ÃÂøõὶàÃÂῶý á½ÂÃÂὸ ààøÃÂÿàüàøÿûÿó÷øÃÂýÃÂÃÂýõ á½ ÃÂù ÃÂñÃÂÃÂñûùÃÂÃÂῶý üὲý ÃÂῶý ÃÂàüüùþìýÃÂÃÂý ãúùÃÂïÃÂýù ÿá½ÂôõὶàõἶÃÂõ ûÃÂóõùý ÿá½Âôὲý üýîü÷àá¼Âþùÿý á¼ÂÃÂÃÂÃÂ÷øõὶàá½ÂÃÂὸ ÃÂÿῦ ãúùÃÂïÃÂýÿàÃÂõÃÂá½¶ ÃÂá¿ÂàÃÂÃÂõÃÂÃÂñýùúá¿ÂÃÂõ ÿá½Âôὲ ÃÂῶý á¼Âú ÃÂìÃÂòÃÂýÿàÿá½Âôὲ ÃÂῶý á¼Âú ÃÂÿÃÂòùûῶýÿÃÂõ ñἵÃÂõàἦÃÂñý á¼ÂÃÂùÃÂÃÂñù ÃÂÃÂûõùàÃÂῶý ÃÂñÃÂÃÂ÷ùõ ààøÃÂñàô᾽ á¼ÂøìÃÂÃÂ÷ÃÂõ ÃÂÿÃÂñῦÃÂñ ÃÂõÃÂÃÂñÃÂøñù."</blockquote>English translation by Jones (1923):<blockquote>"Formerly there was an emporium on this river [the Loire], called Corbilo, with respect to which Polybius, calling to mind the fabulous stories of Pytheas, has said: 'Although no one of all the Massiliotes who conversed with Scipio was able, when questioned by Scipio about Britain, to tell anything worth recording, nor yet any one of the people from Narbo or of those from Corbilo, though these were the best of all the cities in that country, still Pytheas had the hardihood to tell all those falsehoods about Britain.'âÂÂ</blockquote>
Strabo gives no further details about the location of Corbilo besides that it was "á¼ÂüÃÂÃÂÃÂùÿý á¼ÂÃÂá½¶ ÃÂÿÃÂÃÂÃÂù ÃÂῶù ÃÂÿÃÂñüῶù": an emporium formerly (e.g. in Strabo's time; 1st century BC - 1st century AD) on the river Loire. Assuming it to be near the mouth of the Loire in the region of Saint-Nazaire, Couëron and Corsept have been suggested based on toponymic similarity.
Polybius states that together with Narbo and Massalia, Corbilo was amongst the "best of all the cities" in the Greek colonies of Gaul. By Strabo's time, approximately a century and a half later, Corbilo had been abandoned or destroyed. It is implied that Polybius either visited the city in person, or was able to gather intelligence from people who did; likewise it is implied that Pytheas visited it during his voyages.
