FORTIFIED by the conclusion that diffusion from Asia to Central Europe is likely, let us turn to axiom 4-the prehistoric chronology of Central Europe. There the cultural sequence is reasonably clear, at least north of the Bakony and the Little Carpathians. The divisions which I tentatively suggested ten years ago have on the whole been fully justified by recent research. But to what Oriental cultures shall these several phases be compared? Encouraged by the newly revealed proofs of intercourse, let us apply Montelius's fourth axiom to dating the Danubian sequence.
