The Struggle between Urartu and Assyria during the Reign of Rusa, Son of Sarduri: According to the Research of C.F. Lehmann-Haupt
During their 1898–1899 journey through the Armenian Highlands and northern Mesopotamia, C.F. Lehmann-Haupt and the chemist W. Belck explored the presumed region of Musasir, the spiritual centre of Biainili-Urartu, and copied the Topzawa inscription. Lehmann-Haupt treated this bilingual text as a primary source for reconstructing the conflict between Urartu and Assyria under Rusa, son of Sarduri. Sargsyan shows that several of the pioneer Urartologist's reconstructions remain contested: the identity of the king who commissioned the inscription, the chronology of the events, and the causes and route of Sargon II's 714 BCE campaign.
