The last two decades have seen a welcome erosion of traditional dogmas of Alexander scholarship, and a number of hallowed theories, raised on a cushion of metaphysical speculation above the mundane historical evidence, have succumbed to attacks based on rigorous logic and source analysis. The brotherhood of man as a vision of Alexander is dead, as is the idea that all Alexander sources can be divided into sheep and goats, the one based on extracts from the archives and the other (...) mere rhetorical fantasy. One notable theory, however, still flourishes and has indeed been described as one of the few certainties among Alexander's aims. This is the so-called policy of fusion. As so often, the idea and terminology go back to J. G. Droysen, who hailed Alexander's marriage to Rhoxane as a symbol of the fusion of Europe and Asia, which the king recognised as the consequence of his victory. At Susa the fusion of east and west was complete and Alexander, as interpreted by Droysen, saw in that fusion the guarantee of the strength and stability of his empire. Once enunciated, Droysen's formulation passed down the mainstream of German historiography, to Kaerst, Wilcken, Berve and Schachermeyr, and has penetrated to almost all arteries of Alexander scholarship. Like the figure of Alexander himself the theory is flexible and capable of strange metamorphoses. In the hands of Tarn it developed into the idea of all subjects, Greek and barbarian, living together in unity and concord in a universal empire of peace. The polar opposite is an essay of Helmut Berve, written in the heady days before the Second World War, in which he claimed that Alexander, with commendable respect for Aryan supremacy, planned a blending of the Macedonian and Persian peoples, so that the two racially related Herrenvölkerwould lord it over the rest of the world empire. On Berve's interpretation the policy had two stages. Alexander first recognised the merits of the Iranian peoples and placed them alongside the Macedonians in his court and army hierarchy. Next came the ‘Blutvermischung’, the integration of the two peoples by marriage. (shrink)
