the Roman historians, it is impossible to make them harmonise. I cannot, therefore, give you a distinct notion of this vast country, which extends from the frontier of Epirus to that of Pannonia, and stretches even into modern Austria; a clear geographical view is unattainable. Still many points can be discerned, and _Est quadam prodire tenus, si non datur ultra_. No one has ever asked whether anything can be discovered regarding the history of the Illyrians; no one has ever thought of enquiring into it. But Herodotus alludes to traditions of that country, apparently as if they were well known, and he speaks of an expedition of the Illyrians and Encheleans, who invaded Greece and plundered the temple of Delphi. According to another tradition, Cadmus and Hermione, quitting Thebes, went to the Encheleans and died there. These are again, as elsewhere, two countries which are put in connexion by migrations in opposite directions. This allusion to a great expedition with an enormous army, leads us to pay attention also to some other facts, as for example, that the Liburnians, in the innermost μυχὸς of the Adriatic, were quite different from the Illyrians, and are mentioned in relations, in which elsewhere we find the Pelasgians on the coast of Italy; further, among the Illyrians in the neighbourhood of Ragusa, there dwelt a people called HYLLII, who are said, by the compilers of legendary history, to have originally been Greeks, and to have become barbarians (ἐκβαρβαρωθῆναι); lastly, the coast of Dalmatia was inhabited by Pelagonians, whom we also find among the Macedonians and Epirots. Accordingly we here meet with remnants of a Pelasgian population, which survived after the immigration of the great race of the Illyrians. Among these latter are included also the Breunians and Genaunians in Tyrol, and the Iapydes on the northern side of the Alps, in the modern Carniola, and further on beyond the Alps. We may, therefore, look upon it as almost an historical fact, that they were a people that immigrated from the north, conquered the Dalmatian mountains, and penetrated as far as the heights of Epirus, which formed a barrier to their further progress.
