During the two centuries in which Britain had been forgotten by the rest of Europe, great events, most of them disastrous events, had been happening in the world. The imperial city, Rome, had been four times captured and plundered by barbarian armies. After the third of these captures (that by Totila in 546), we are told that the mighty city remained for six weeks absolutely empty of inhabitants, neither man nor beast being left therein. During these two centuries the vast empire of Attila the Hun which seemed likely at one time to be a universal monarchy had risen into greatness and had fallen into ruin; so, too, had risen and fallen the fair fabric raised in Italy by the converted barbarian Theodoric; Clovis the Frank had become, from chief of a petty principality, lord of a mighty realm, which under his sons had spread over the greater part of the two countries which we now call France and Germany; Justinian had framed his imperishable code, and the Bishop of Rome had become the unquestioned patriarch of the west. Two references to our island made by the greatest historian of the period serve to emphasise its utter seclusion from the world of civilisation and culture. Procopius in his immortal history of the Gothic siege of Rome,[40] tells us that at a certain period of the blockade (537) when the Gothic leaders began to despair of taking the city they opened negotiations with Belisarius, the imperial general, and endeavoured to persuade him to retire from Italy on condition of receiving a formal cession of the island of Sicily. The absurdity of the suggestion consisted in this, that Sicily, which was the natural prize of the greatest sea power in the Mediterranean, was already hopelessly lost to the Gothic kingdom; and this fact gave point to the sarcastic reply of Belisarius: “And we, too, will allow the Goths to possess the whole island of Britain which is much larger than Sicily and which _once_ belonged to the Romans, as Sicily once belonged to you. For when any one has received a favour it is fitting that he should repay it in kind.” So utterly had Britain fallen out of the orbit of the empire that a heroic Roman general could even afford to joke over its disappearance.
