Notes on the Evidence bearing 
But he adds that it will be safer to assume that the British 
Celts belonged to the later Bronze Age, as well as the Age of 
Iron. It is also necessary to remember that bronze would 
remain in use for many purposes after the introduction of 
iron, and that iron articles deposited in tumuli must have 
often perished while bronze ones have endured. 
More than two centuries after the voyage of Pytheas, 
Britain was visited by an eminent Greek named Posidonius, 
who gave some account of the people of Belerion or Cornwall 
and their tin-works. Posidonius is supposed to be the 
authority of Diodorus Siculus for the statement that the 
people of Britain had mean habitations, made for the most 
part of rushes and sticks, and that their harvest consisted in 
cutting off the ears of corn and storing them in pits under¬ 
ground, some of the corn which had been longest stored being 
taken out each day for food. As Pytheas confined his explor¬ 
ations to Eastern Britain, it is net surprising that he found a 
more advanced civilisation there, where there was constant 
intercourse with the Continent, than Posidonius did, two 
centuries later, in parts of the west little visited by merchants. 
Posidonius, however, remarks that the inhabitants of Belerium 
are very fond of strangers, and, from their intercourse with 
foreign merchants, are civilised in their manner of life. But, 
of course, the most primitive habits might exist a very few 
miles away from the commercial centres and routes, alike in 
the east and the west. 
In b.c. 55 and 54, some thirty or forty years after the visit 
of Posidonius, the two voyages of Julius Caesar to Britain 
took place ; and we learn from his remarks on the reasons 
for visiting our island how little was known about it in Gaul. 13 
Caesar had been annoyed to find that in the wars of the 
Bomans with the Gauls the latter were accustomed to receive 
help from Britain. He also found that merchants who had 
been in the habit of crossing over to Britain knew but the 
sea-coast and the parts opposite Gaul, and could tell him 
neither the size of the island, the numbers of its inhabitants, 
nor anything about their manners and customs, their modes
