Note 2254 — THE CASSITERIDES, ICTIS, AND THE BRITISH TRADE IN TIN
Reading edition
De Mortillet’s identification of the Cassiterides with the islands off the coast of Brittany is not worth discussing. Tin was apparently worked in the Morbihan in the Bronze Age (W. Boyd Dawkins, Early Man in Britain, pp. 403-4), but not in any of the Breton islands; nor is there any evidence that Gallic tin was ever an object of foreign commerce.
