The Work Endures

I
Carved, Not Cast
Each slab begins as raw cliff basalt. No mold, no pour — only the chisel.
II
Depth in Six Grades
From hairline incision to full undercut relief, shadow itself becomes material.
III
Patina Is the Finish
Two thousand years of weather on the surface. We call that complete.
IV
One Lineage, One Hand
Master to apprentice, Sassanid tradition unbroken since the third century.
