Now it has long been realised that swords of these types had been evolved somewhere in the Danube basin, and it has been suggested that this had taken place in the south Danubian region.[270] It becomes important, therefore, to determine whereabouts in the Celtic cradle these types originated. Details of the distribution of this and of other types will be discussed in the next chapter; here it will be sufficient to summarise. As far as I have been able to ascertain, six specimens only of this type are known, and one of these is so unlike the others that we must look upon it as a later variant. Of the five, one was found in the Friuli, at the head of the Adriatic, one in a tomb in Schleswig-Holstein, while the other three were found somewhere in Hungary. Of these the exact sites at which two were found are unknown, but the third is said to have been dredged out of the Danube near Buda-Pest.[271] We may, I think, conclude from this that it was in the plain of Hungary, where the Nordic steppe-folk were living in relative purity, still leading, perhaps, a nomadic life, that these swords were developed. The origin seems to have been in the plain rather than in the mountain zone, though subsequent types have been found frequently in the latter. It is the Hungarian plain, then, we must consider as the centre of dispersal, and, as far as possible, Hungarian rather than other examples will be taken as the true types, of which others will be considered as variants.
