In perfect accordance with this are the statements of the Irish themselves respecting the many Scandinavian merchants in the towns of the Ostmen. An old Irish manuscript relating to the battle of Clontarf (“Cath Chluana Tarbh”) states that, after the battle, “no Danes were left in the kingdom, except such a number of artisans and merchants in Dublin, Waterford, Wexford, Cork, and Limerick, as could be easily mastered at any time, should they dare to rebel; and these King Brian very wisely permitted to remain in these seaport towns, for the purpose of encouraging trade and traffic, as they possessed many ships, and were experienced sailors.” Duald Mac Firbis also says in his chronicles that in his time (1650) “most of the merchants in Dublin were the descendants of the Norwegian-Irish king, Olaf Kvaran.” That the Norwegians and Danes must really have possessed themselves of the Irish trade, and given it a new impulse, clearly appears from the circumstance that the Norwegian kings in Ireland were the first who caused coins to be minted there. One of these coins, which formerly belonged to the Timm’s collection in Copenhagen, but which is now in the collection of M. von Römer, in Dresden, seems (according to the opinion of that distinguished numismatologist C. J. Thomsen, of Copenhagen) to have been minted by a Scandinavian king of Dublin, as early as the eighth or ninth century. It is an imitation of the ancient Merovingian coins, and has a remarkable inscription on the obverse, half in runes and half in Latin letters, but which can scarcely be read otherwise than “Cunut u Dieflio,” or, Canute in Dublin. [Illustration: [++] Coin: Canute in Dublin] The Old Northmen call Dublin “Dýflin,” whence the surrounding district also obtained the name of “Dýflinarskiri,” as appears in the Sagas. This legible inscription encircles the bust of a royal warrior, clad in scale armour. On the reverse are seen the letters ENAE, and under them two figures, both turning their faces upwards in the same direction, and each extending a very large hand, whilst in their other hands, joined together, they hold a ring, as if they were taking an oath on the holy ring. They are, besides, represented as standing before, or sitting on, an elevated platform (perhaps an altar?), under which is a mark (∾) like the letter S placed on its side. These figures probably contain an allusion to some treaty concluded between an Irish king and the Scandinavian king Canute.
