Chapter 2 of Geoffrey of Monmouth's (1100-1155) "History of the Kings of Britain" :
"Britain, the best of islands, is situated in the Western Ocean, between France and Ireland, being eight hundred miles long, and two hundred broad. It produces every thing that is useful to man, with a plenty that never fails. It abounds with all kinds of metal, and has plains of large extent, and hills fit for the finest tillage, the richness of whose soil affords variety of fruits in their proper seasons. It has also forests well stored with all kinds of wild beasts; in its lawns cattle find good change of pasture, and bees variety of flowers for honey. Under its lofty mountains lie green meadows pleasantly situated, in which the gentle murmurs of crystal springs gliding along clear channels, give those that pass an agreeable invitation to lie down on their banks and slumber. It is likewise well watered with lakes and rivers abounding with fish; and besides the narrow sea which is on the Southern coast towards France, there are three noble rivers, stretching out like three arms, namely, the Thames, the Severn, and the Humber; by which foreign commodities from all countries are brought into it. It was formerly adorned with eight and twenty cities, of which some are in ruins and desolate, others are still standing, beautified with lofty church-towers, wherein religious worship is performed according to the Christian institution. It is lastly inhabited by five different nations, the Britons, Romans, Saxons, Picts, and Scots; whereof the Britons before the rest did formerly possess the whole island from sea to sea, till divine vengeance, punishing them for their pride, made them give way to the Picts and Saxons. But in what manner, and from whence, they first arrived here, remains now to be related in what follows."
