Within the city, in what may be strictly called ancient London, where the Sagas already mention a St. Olaf’s Church, there are to be found at this day no fewer than three churches consecrated to St. Olave: namely, in Silver Street; at the north-west corner of Seething Lane, Tower Street; and in the Old Jewry (St. Olave’s Upwell). The two last-named stand in the eastern extremities of the city, yet within its ancient boundaries. In the same neighbourhood, near London Bridge, there is also a church dedicated to St. Magnus the Martyr, which likewise undoubtedly owes its origin to the Northmen, either the Norwegians or Danes. St. Magnus was a Norwegian jarl, who was killed in the twelfth century in Orkney, where the cathedral in Kirkwall is also consecrated to him. That so many churches in London should be named after these Norwegian saints, Olaf and Magnus, who, moreover, were not canonized till after the death of Canute the Great, and the overthrow of the Danish dominion in England, furnishes no mean evidence of the influence of the Northmen in London. It confirms in a remarkable manner the truth of the old statements, that the Danes who dwelt in London could at times even turn the scales at the election of a king; as, for instance, after the death of Canute the Great. An English chronicler, speaking of the power of the Danes at that period, adds, that the citizens of London had, by reason of their frequent intercourse with “_the barbarians_” (the Danes), almost adopted their manners and customs. And it was, indeed, natural that the long voyages of the Northmen, and the important commerce carried on between the countries of Scandinavia and England, should have long secured to the northern merchants an influential position in a city like London, which was in the highest degree a commercial city, and particularly when these merchants had once been established there in great numbers.
