The Sabaeans did not write on surfaces; they removed stone until the letter existed. Musnad is an abjad of consonants drawn to engineering tolerances — uniform stroke width, squared terminals, even gaps — set on a ruled lattice that the mason left visible when he was done.

This system treats the page as dressed ashlar. Type reads as depth rather than ink, panels behave like inscribed blocks with a chamfered cut, and tables borrow their plainness from the Marib dam records: workers counted, quantities listed, costs aligned. Bronze and alabaster do the accenting. Nothing is decorative that is not also load-bearing.
