Excerpt:
"The literature of every modern country is made up of many elements, contributed by various races; and has been modified at different times by foreign influences. Thus, among the ancient Celtic inhabitants of our islands, the peoples whom the Romans found here, the Welsh have given us the materials of the famous romances of King Arthur, and from the Gaelic tribes of Ireland and Scotland come the romances of heroes less universally known, Finn, Diarmaid, Cuchulain, and the rest. But the main stock of our earliest poetry and prose, like the main stock of our language, is Anglo-Saxon. The Anglo-Saxon tribes who invaded Britain, and after the departure of the Romans (411) conquered the greater part of the island, must have had a literature of their own, and must have brought it with them over sea."
