At that time the city of Rome was about 700 years old, but the Roman empire was much younger. As late as 211 ВС Rome had narrowly escaped destruction by the Carthaginian general, Hannibal. But Hannibal's defeat left Rome without а serious rival, and by Caesar's time it controlled an empire that stretched from Spain to the Near East.

Two places more different than imperial Rome and Celtic Britain could hardly have existed. Roman society was urban, with grand public buildings built of marble. Britain was а country of mud huts, with no settlement large enough to be called а town. An upper-class Roman lived in greater comfort than any Britisher before the 15th century. His house even had central heating.

The Romans, as heirs of the civilization of Ancient Greece, were interested in art, philosophy and history (Caesar himself wrote good military history in simple prose). The British could neither read nor write. They were not savages, and in some ways Celtic art was superior to Roman, or so it seems to us, but the Romans naturally thought of them as hopelessly primitive barbarians. То the Romans - and to many non-Romans too - there was but one worthwhile form of society, and that was their own. The only useful function of other peoples was to contribute to the glory of Rome.

Britain was а mysterious isle to the Romans. But Caesar knew it contained valuable minerals, and he knew also that the British were helping their cousins in Gaul against Rome. Не decided on invasion. ...

Long ago, the British Isles were not isles at all. Britain was part of the European continent: the English Channel did not exist and East Anglia merged into the Netherlands. Then, about 10,000 years ago - when the last Ice Age had ended, when the bones of the last mammoth had sunk into the mud of the Thames valley, when the climate grew warmer - new rivers and seas were formed and Europe was slowly formed into its present shape.

The people of Britain, like their cousins оn the continent, were simple hunters who lived оn the flesh of wild animals, which they shot with flint-tipped arrows or caught in traps. They killed fish in the estuaries and shallow rivers with spears made from the antlers of deer. They gathered wild fruit, nuts and honey, and probably ate snails, caterpillars and other grubs. They did not build permanent houses, but moved from place to place, sheltering in caves in cold weather.

The people of Britain lagged behind the people of certain warmer lands in their development. While they were still living in caves and scratching about for insects to eat, the Egyptians were building pyramids and writing literature.

Of all the stages between the cave and the skyscraper, perhaps man's greatest leap forward was taken when he became а farmer. The Stone Age farmer of about 5,000 years ago had to clear patches in the forests which covered most of Britain that was not barren heath or swamp. Не cut down trees with stone axes, burned off the scrub, and tilled the ground with а stone-headed hoe. Не kept half-wild cattle and pigs in the forest, where they could find their own food, and in treeless parts, like northern Scotland, he kept sheep. The people who grew grain in southern England had flint sickles to reap the harvest.
