The accounts of the Greeks respecting the Illyrians are very different from the later ones of the Romans. The Greeks, e.g., mention the Manians, Nestians, Hyllians, and, on the south of Lissos, the Taulantians as the most important among the Illyrian nations; but during the time of the Romans they do not occur at all, although Dalmatia acts a considerable part in history: in their place Dalmatians are mentioned all along the coast, whose name does not occur at all in the geography of the Greeks. Thus the Taulantians are not spoken of in the wars against Teuta, Demetrius of Pharos, and afterwards in the first war against Philip, although Apollonia and Epidamnus act a very prominent part; in their stead we hear of Ardyaeans and Parthinians. Whether these latter did not exist during the Greek period under these names, is a question which I will not decide. In early times the Alemannians and Franks do not occur under these names, and the other nations which do occur, are different from them; this justifies the inference, that several of the latter united into one people: in the same manner the Taulantians may either have divided themselves, or other tribes may have united under that name. I say this to prevent your falling into the mistake of believing that all these statements refer to the same period. It is this error which has made of the topography of Rome such a chaos, that no man can find his way out of it, unless he takes the trouble of commencing the investigations afresh from the very beginning: in this manner alone he can find his way, for in Roman topography buildings are mentioned by the side of one another, which are separated by four or five centuries. It is evident, that the mighty invasion of the Gauls threw the whole country of Illyricum and all its tribes into confusion, in consequence of which the Scordiscans permanently established themselves in Sirmia (Slavonia), Servia, and Bosnia, and expelled the Triballians, so that other nations penetrated into Upper Macedonia, partly subduing and partly expelling its inhabitants, who then formed settlements in Thrace. This great convulsion accounts for the difference between the earlier and later condition of Illyricum.
