The Dumnonii: The Tin from the End of the Island

History & Finds The Dumnonii: The Tin from the End of the Island placeholder

The Dumnonii were a Celtic people in the far south-west of Britain – in today's Cornwall and Devon (whose name derives from them).

Tin for the world

Their peninsula was rich in tin – the rare metal that turns copper into bronze. Long before Rome a long-distance trade ran from here to the Mediterranean; ancient authors report of the tin island "Ictis".

Far from Rome

Lying far in the west, the Dumnonii were only loosely ruled by Rome. Celtic language and culture held on here especially long – a bridge to the later Cornish language.

"The inhabitants of the headland Belerion … dig the tin and skilfully work it."after Diodorus, Library 5 (public domain, own translation)
What is documented: Dumnonii in the south-west of Britain, the tin wealth of Cornwall and the ancient tin trade (Diodorus, Strabo); the derivation of the name Devon.
What is interpretation: The exact location of the tin island "Ictis" is still disputed (St Michael's Mount is a candidate). How strongly the early trade really ran is inferred from few passages.

The Dumnonii lead to the western end of the Celtic world. Continue with the Silures and Veneti.
