This corrupt appellation has been diffused in the thirteenth century by the merchants and bankers, the Italian posterity of these savage warriors: but the original name of Langobards is expressive only of the peculiar length and fashion of their beards.[18] About the time of Augustus and Trajan, a ray of historic light breaks on the darkness of their antiquities, and they are discovered, for the first time, between the Elbe and the Oder. Fierce beyond the example of the Germans, they delighted to propagate the tremendous belief that their heads were formed like the heads of dogs, and that they drank the blood of their enemies whom they vanquished in battle. The smallness of their numbers was recruited by the adoption of their bravest slaves; and alone, amidst their powerful neighbours, they defended by arms their high-spirited independence. [Illustration: A GOTHIC CHIEF] In the tempest of the north, which overwhelmed so many names and nations, this little bark of the Lombards still floated on the surface. They gradually descended towards the south and the Danube, and at the end of four hundred years[19] they again appear with their ancient valour and renown. Their manners were not less ferocious. The assassination of a royal guest was executed in the presence and by the command of the king’s daughter, who had been provoked by some words of insult and disappointed by his diminutive stature;[20] and a tribute, the price of blood, was imposed on the Lombards by his brother the king of the Heruli. Adversity revived a sense of moderation and justice, and the insolence of conquest was chastised by the signal defeat and irreparable dispersion of the Heruli, who were seated in the southern provinces of Poland.[21] The victories of the Lombards recommended them to the friendship of the emperors; and at the solicitation of Justinian they passed the Danube to reduce, according to their treaty, the cities of Noricum and the fortresses of Pannonia. But the spirit of rapine soon tempted them beyond these ample limits; they wandered along the coast of the Adriatic as far as Dyrrhachium, and presumed, with familiar rudeness, to enter the towns and houses of their Roman allies, and to seize the captives who had escaped from their audacious hands. These acts of hostility, the sallies, as it might be pretended, of some loose adventurers, were disowned by the nation and excused by the emperor; but the arms of the Lombards were more seriously engaged by a contest of thirty years, which was terminated only by the extirpation of the Gepidæ.
