Of their moral habits we may best judge by their religion. All we know of their history seems to prove that with them might was right, and outlawry the only penalty of their laws. A man guilty of murder was compelled to quit the country, unless his superior daring and the number of his friends and followers enabled him, by more atrocious and wholesale murders, still to become a great chieftain and even aspire to supreme power. Iceland was colonized by outlaws from Norway; and the frequent changes of dynasty in pagan times prove that among them, as among barbarous tribes generally, brute force was the chief source of law and authority. That outlawry was not esteemed a stain on the character is sufficiently demonstrated by the fact that the mere accident of birth made outlaws of all the children of chieftains with the exception of the eldest born; the necessity for the younger sons abandoning their home and native country, and roaming the ocean in search of plunder, being exactly equivalent, according to their opinion and customs, to criminal outlawry of whatever character. This, at least, many authors assert without hesitation. Their domestic habits were fit consequences of such a state of society. There could exist no real tie of kindred, no filial or brotherly affection among men living under such a social system. The gratification of brutal passions and the most utter selfishness constituted the rule for all; and even the fear of an inexorable judge after death could not restrain them during life, as might have been the case among other pagan nations, since the hope of reaching their Walhalla depended for its fulfilment on murder or suicide. With their system of warfare we are better acquainted than with any thing else belonging to them, as the main burden of their songs was the recital of their barbarous expeditions. It is, indeed, difficult for a modern reader to wade through the whole of their Edda poems, or even their long sagas, so full is their literature of unimaginable cruelties. Yet a general view of it is necessary in order to understand the horror spread throughout Europe by their inhuman warfare. As soon as the warm breeze of an early spring thaws the ice on his rivers and lakes, the Scandinavian Viking unfurls his sail, fills his rude boat with provisions, and trusts himself to the mercy of the waves. Should he be alone, and not powerful enough to have a fleet at his command, he looks out for a single boat of his own nation--there being no other in those seas. Urged by a mutual impulse, the two crews attack each other at sight; the sea reddens with blood; the savage bravery is equal on both sides; accident alone can decide the contest. One of the crews conquers by the death of all its opponents; the plunder is transferred to the victorious boat; the cup of strong drink passes round, and victory is crowned by drunkenness.
