The orator Cicero, in a letter to Trebatius, then serving with the army in Britain, sarcastically advised him to capture and convey one of these vehicles to Italy for exhibition; but we do not hear that any specimen of the British war-chariot was ever seen in Rome.
It is only in the tumuli along the coast, or in those of the Romano-British period, that iron implements are ever found; whilst in the ancient burying places of the interior of the country they are altogether wanting.

Herodian says of the British pursued by Severus through the fens and marshes of the east coast, that they wore iron hoops round their middles and their necks, esteeming them as ornaments and tokens of riches, in like manner as other barbarous people then esteemed ornaments of silver and gold.

Their only money, according to Caesar, consisted of pieces of brass or iron, reduced to a certain standard weight.[11] It is particularly important to observe, says M.
Worsaae, that all the antiquities which have hitherto been found in the large burying places of the Iron period, in Switzerland, Bavaria, Baden, France, England, and the North, exhibit traces more or less of Roman influence.[12] The Romans themselves used weapons of bronze when they could not obtain iron in sufficient quantity, and many of the Roman weapons dug out of the ancient tumuli are of that metal.

They possessed the art of tempering and hardening bronze to such a degree as to enable them to manufacture swords with it of a pretty good edge; and in those countries which they penetrated, their bronze implements gradually supplanted those which had been previously fashioned of stone.

Great quantities of bronze tools have been found in different parts of England,--sometimes in heaps, as if they had been thrown away in basketfuls as things of little value.
