Cornwall (district): History
=== Prehistory, Roman and post-Roman periods ===
Humans reoccupied Britain after the last Ice Age. The area now known as Cornwall was first inhabited in the Palaeolithic and Mesolithic periods. It continued to be occupied by Neolithic and then by Bronze Age people.
Cornwall in the Late Bronze Age formed part of a maritime trading-networked culture which researchers have dubbed the Atlantic Bronze Age system, and which extended over most of the areas of present-day Ireland, England, Wales, France, Spain, and Portugal.
During the British Iron Age, Cornwall, like all of Britain (modern England, Scotland, Wales, and the Isle of Man), was inhabited by a Celtic-speaking people known as the Britons with distinctive cultural relations to neighbouring Brittany. The Common Brittonic spoken at this time eventually developed into several distinct tongues, including Cornish, Welsh, Breton, Cumbric and Pictish.
The first written account of Cornwall comes from the 1st-century BC Sicilian Greek historian Diodorus Siculus, supposedly quoting or paraphrasing the 4th-century BCE geographer Pytheas, who had sailed to Britain:
The inhabitants of that part of Britain called Belerion (or Land's End) from their intercourse with foreign merchants, are civilized in their manner of life. They prepare the tin, working very carefully the earth in which it is produced ... Here then the merchants buy the tin from the natives and carry it over to Gaul, and after traveling overland for about thirty days, they finally bring their loads on horses to the mouth of the Rhône.
The identity of these merchants is unknown. It has been theorized that they were Phoenicians, but there is no evidence for this. Professor Timothy Champion, discussing Diodorus Siculus's comments on the tin trade, states that "Diodorus never actually says that the Phoenicians sailed to Cornwall. In fact, he says quite the opposite: the production of Cornish tin was in the hands of the natives of Cornwall, and its transport to the Mediterranean was organized by local merchants, by sea and then overland through France, passing through areas well outside Phoenician control." Isotopic evidence suggests that tin ingots found off the coast of Haifa, Israel, may have been from Cornwall. Tin, required for the production of bronze, was a relatively rare and precious commodity in the Bronze Age – hence the interest shown in Devon and Cornwall's tin resources. (For further discussion of tin mining see the section on the economy below.)
In the first four centuries AD, during the time of Roman dominance in Britain, Cornwall was rather remote from the main centres of Romanization – the nearest being Isca Dumnoniorum, modern-day Exeter. However, the Roman road system extended into Cornwall with four significant Roman sites based on forts: Tregear near Nanstallon was discovered in the early 1970s, two others were found at Restormel Castle, Lostwithiel in 2007, and a third fort near Calstock was also discovered early in 2007. In addition, a Roman-style villa was found at Magor Farm, Illogan in 1935. Ptolemy's Geographike Hyphegesis mentions four towns controlled by the Dumnonii, three of which may have been in Cornwall. …
