Seers Read the Silent Sky

From C4.4, Kay Khosrow Hears of Afrasiab’s Advance. It illustrates C4.4.24–29:

C4.4.24
Two days and nights the armies held their ground;No warrior moved his lips to make a sound.
C4.4.25
The horsemen mounted firm on either side,The footmen formed before them, rank and wide.
C4.4.26
The world became a mountain, iron-made;The heavens seemed in jowshans all arrayed.
C4.4.27
Before the King and Shah seers drew near,With anxious minds and tables of the sphere.
C4.4.28
With astrolabes they searched the turning sky,To learn on whom its favor now would lie.
C4.4.29
But heaven watched the battle from on high;The baffled seers could offer no reply.
