King Olaf Tryggveson is the first Norseman who is expressly mentioned to have been in England by our English History books, new or old; and of him it is merely said that he had an interview with King Ethelred II. at Andover, of a pacific and friendly nature,--though it is absurdly added that the noble Olaf was converted to Christianity by that extremely stupid Royal Person. Greater contrast in an interview than in this at Andover, between heroic Olaf Tryggveson and Ethelred the forever Unready, was not perhaps seen in the terrestrial Planet that day. Olaf or "Olaus," or "Anlaf," as they name him, did "engage on oath to Ethelred not to invade England any more," and kept his promise, they farther say. Essentially a truth, as we already know, though the circumstances were all different; and the promise was to a devout High Priest, not to a crowned Blockhead and cowardly Do-nothing. One other "Olaus" I find mentioned in our Books, two or three centuries before, at a time when there existed no such individual; not to speak of several Anlafs, who sometimes seem to mean Olaf and still oftener to mean nobody possible. Which occasions not a little obscurity in our early History, says the learned Selden. A thing remediable, too, in which, if any Englishman of due genius (or even capacity for standing labor), who understood the Icelandic and Anglo-Saxon languages, would engage in it, he might do a great deal of good, and bring the matter into a comparatively lucid state. Vain aspirations,--or perhaps not altogether vain.
