In the initial decades following the discovery of the epic in the late nineteenth century a general consensus emerged attributing its theme to the struggle of four generations of Sassoun's warriors against Muslim rule in the 8th to 10th centuries. The pioneers of this interpretation of the epic were the philologist Manuk Abeghian in Armenia and academic Joseph Orbeli at the Hermitage Museum in Leningrad, who argued that there are no characters in the epic that could be attributed to a historical person from before the 10th century.
