Fourth-generation Sassoun hero; son of David of Sassoun; final figure of the Sasna Tsřer cycle. The accidental-killing-of-his-father episode structurally parallels broader Indo-European tragic-misidentification material (Ossetian Akhsartæg killing Akhsar; Greek Oedipus killing Laius; Persian Sohrab-and-Rostam). The subsequent curse — paradoxical immortality-in-stasis without ability to die or produce descendants — produces the eschatological-waiting-figure status: sealed in the Raven's Rock cave (Agravakar) with his magical horse Kourkik Jalali, awaiting the end of the world to emerge and right injustices. The sealed-hero-awaiting-the-end is the eschatological climax of the Sasna Tsřer and one of the most-distinctive Armenian eschatological figures, with structural parallels to Welsh Arthur-in-Avalon, Norse Holger Danske, and the broader Indo-European sleeping-king-awaiting-return mythologem. The Mher-name preserves the Iranic polytheistic Mihr (Mithra), with the eschatological-waiting-figure aspect potentially preserving the Avestan Mithra-as-eschatological-judge complex. The vitalStatus "sealed-awaiting-end-of-world" is registry-distinctive — Mher the Younger is neither living nor dead in the conventional sense but in suspended eschatological stasis.
