Van artefact 1a1: this really struck me. It's a stretch of the cliff face of the Rock of Van with dozens and dozens of what may be Armenian Crosses/Siroun Crosses and/or Forked Crosses (Croix Fourchées) etched into it, in the style of Khachkars/Khach'k'ars, interspersed with Armenian script.

I had assumed that the crosses were Armenian Crosses, but, overwhelmingly, they resemble Forked Crosses and lack the Armenian Cross's characteristic 'Suns represent[ing] the light of Christianity' adorning each corner (although I suppose that might have been a practical matter).
