Alfred brought high qualifications to the task of translating and editing Orosius.[25] In his boyhood he had twice made journeys to Rome, which, as regards danger and hardships, may be compared to an expedition to Lhasa at the present day. In after life he had become very intimately acquainted with the topography of his native island, from the Humber to the shores of the Channel, and from the Severn to the East Anglian coast. As a military tactician he knew each river, valley, hill range, and plain; as an administrator he had examined the capabilities of every district; and as a naval commander, the harbours and estuaries, the tides and currents were familiar to him. So far as his personal knowledge extended, Alfred was a trained geographer. He was also in a position to increase the information derived from his own personal experiences by diligently collecting materials from those foreigners who frequented his court, and by reading. He had the gift of assimilating the knowledge thus acquired, and he studied most diligently. Above all, he was eager to investigate unknown things for the great end he always had in view—the good of his people. Alfred’s design was to collect the best and most extensive geographical information, without confining himself to the text of Orosius. Thus he commences his geographical work with a very lucid account of the peoples of central Europe and of their relative positions, which is not in the work of Orosius, but was composed by the king himself from his own sources of information. It is the only account from which such details in that age can be derived.
