Second-generation Sassoun hero; son of Sanasar; lion-slayer and Dev-slayer; father of David of Sassoun (the central hero of the epic) and of his half-brother Misra Melik. The Mher-name preserves the Iranic polytheistic Mihr (Mithra) as a heroic-personal-name within the medieval Christian-Armenian Sassoun frame — reflecting the Iranic-syncretic substrate underneath the medieval epic. The two-marriage paternal structure (first to Armaghan/Misra Khanum of Egypt; second to Khandut Khatun) produces the half-sibling rivalry between Misra Melik and David of Sassoun that drives much of Cycle 3 of the epic. The Mets ("Great, Elder") superlative-positioning distinguishes him from his grandson Mher the Younger (the fourth-generation hero sealed in the Raven's Rock cave). Iconographic attributes include the lion-skin cloak, the lightning-sword tour-keatsakar (inherited from Sanasar), and the immortal magical horse Kourkik Jalali (which David subsequently inherits).
