The Iapodes, then, or Japydes, of the authors in question, are neither an obscure nor an inconsiderable nation. They extend along the sea-coast of the Adriatic. They occupy the valley of the Culpa. They are Illyrian, but conterminous with Pannonia.
As Pliny seems to have taken his name from Strabo, the authors just quoted may all be called Greek. With the latest of them we lose the forms [a]Ἰάποδες] or Japydes.
As the Roman empire declines and its writers become less and less classical, their geographical records become less systematic and more fragmentary; and it is not till we get to the times of Probus and Maximian that we find any name approaching [a]Ἰάποδες]. Probus, however, plants a colony of Gepidæ within the empire (Vopiscus, Vit. Pub. c. 18). The Tervings also fight against the Vandals and Gipedes (Mamertinus in Genethl. Max. c. 17). Sidonius makes the fierce Gepida (Gepida trux) a portion of the army of Attila. Finally, we have the Gepidæ, the Lombards, and the Avars, as the three most prominent populations of the sixth century.
The Gepid locality in the fifth century is the parts about Sirmium and Singidunum—Alt Schabacz and Belgrade—within the limits of Pannonia, and beyond those of Illyricum, i. e. a little to the north of the occupancy of the Iapodes and Japydes of Strabo and Pliny.
There is, then, a little difference in name between Japydes and Gepidæ, and a little difference in locality between the Gepids and Iapodes. I ask, however, whether this is sufficient to raise any doubt as to the identity of the two words? Whether the populations they denoted were the same is another matter. I only submit that, word for word, Japyd and Gepid are one. Yet they have never been considered so. On the contrary, the obscure history of the Japydes is generally made to end with Ptolemy; the more brilliant one of the Gepidæ to begin with Vopiscus. This may be seen in Gibbon, in Zeuss, or in any author whatever who notices either, or both, of the two populations.
There is a reason for this; it does not, however, lie in the difference of name. Wider ones than this are overlooked by even the most cautious of investigators. Indeed, the acknowledged and known varieties of the word Gepidæ itself, are far more divergent from each other than Gepidæ is from Japydes. Thus Gypides, [a]Γήπαιδες], [a]Γετίπαιδες], are all admitted varieties,—varieties that no one has objected to.
Nor yet does the reason for thus ignoring the connexion between Gepidæ and Japydes lie in the difference of their respective localities. For a period of conquests and invasions, the intrusion of a population from the north of Illyricum to the south of Pannonia is a mere trifle in the eye of the ordinary historian, who generally moves large nations from one extremity of Europe to another as freely as a chess-player moves a queen or castle on a chess-board. In fact, some change, both of name and place, is to be expected. The name that Strabo, for instance, would get through an Illyrian, Vopiscus or Sidonius would get through a Gothic, and Procopius through (probably) an Avar, authority—directly or indirectly.
The true reason for the agreement in question having been ignored, lies in the great change which had taken place in the political relations of the populations, not only of Illyricum and Pannonia, but of all parts of the Roman empire. The Japydes are merely details in the conquest of Illyricum and Dalmatia; the Gepid history, on the contrary, is connected with that of two populations eminently foreign and intrusive on the soil of Pannonia,—the Avars and the Lombards. How easy, then, to make the Gepidæ foreign and intrusive also. Rarely mentioned, except in connexion with the exotic Goth, the exotic Vandal, the exotic Avar, and the still more exotic Lombard, the Gepid becomes, in the eyes of the historian, exotic also.
This error is by no means modern. It dates from the reign of Justinian; and occurs in the writings of such seeming authorities as Procopius and Jornandes. With many scholars this may appear conclusive against our doctrine; since Procopius and Jornandes may reasonably be considered as competent and sufficient witnesses, not only of their foreign origin, but also of their Gothic affinities. Let us, however, examine their statements. Procopius writes, that "the Gothic nations are many, the greatest being the Goths, Vandals, Visigoths, and Gepaides. They were originally called the Sauromatæ and Melanchlæni. Some call them the Getic nations. They differ in name, but in nothing else. They are all whiteskinned and yellow-haired, tall and good-looking, of the same creed, for they are all Arians. Their language is one, called Gothic." This, though clear, is far from unexceptionable (B. Vand. i. 2). Their common language may have been no older than their common Arianism.
Again, the Sciri and Alani are especially stated to be Goths, which neither of them were,—the Alans, not even in the eyes of such claimants for Germany as Grimm and Zeuss.
