If we were to receive the chronology while rejecting the embellishments of the Bards, Turgesius must have first come to Ireland with one of the expeditions of the year 820, since they speak of him as having been "the scourge of the country for seventeen years," before he assumed the command of the forces landed from the fleet of 837. Nor is it unreasonable to suppose that an accurate knowledge of the country, acquired by years of previous warfare with its inhabitants, may have been one of the grounds upon which the chief command was conferred on Turgesius. This knowledge was soon put to account; Dublin was taken possession of, and a strong fort, according to the Scandinavian method, was erected on the hill where now stands the Castle. This fort and the harbour beneath it were to be the _rendezvous_ and arsenal for all future operations against Leinster, and the foundation of foreign power then laid, continued in foreign hands, with two or three brief intervals, until transferred to the Anglo-Norman chivalry, three centuries and a half later. Similar lodgment was made at Waterford, and a third was attempted at Limerick, but at this period without success; the Danish fort at the latter point is not thought older than the year 855. But Turgesius—if, indeed, the independent acts of cotemporary and even rival chiefs be not too often attributed to him—was not content with fortifying the estuaries of some principal rivers; he established inland centres of operation, of which the cardinal one was on Lough Ree, the expansion of the Shannon, north of Athlone; another was at a point called Lyndwachill, on Lough Neagh. On both these waters were stationed fleets of boats, constructed for that service, and communicating with the forts on shore. On the eastern border of Lough Ree, in the midst of its meadows, stood Clonmacnoise, rich with the offerings and endowments of successive generations. Here, three centuries before, in the heart of the desert, St. Kieran had erected with his own hands a rude sylvan cell, where, according to the allegory of tradition, "the first monks who joined him," were the fox, the wolf, and the bear; but time had wrought wonders on that hallowed ground, and a group of churches—at one time, as many as ten in number—were gathered within two or three acres, round its famous schools, and presiding Cathedral. Here it was Turgesius made his usual home, and from the high altar of the Cathedral his unbelieving Queen was accustomed to issue her imperious mandates in his absence. Here, for nearly seven years, this conqueror and his consort exercised their far-spread and terrible power. According to the custom of their own country—a custom attributed to Odin as its author—they exacted from every inhabitant subject to their sway—a piece of money annually, the forfeit for the non-payment of which was the loss of the nose, hence called "nose-money." Their other exactions were a union of their own northern imposts, with those
