Manijeh Lights the Signal Fire

From C2.23, Bijan Learns Rostam Is Coming. It illustrates C2.23.76–82:

C2.23.76
Manijeh rushed for wood; with eager treadShe climbed like birds where spreading branches led.
C2.23.77
She watched the sun, the wood upon her breast:When would night raise its head above the crest?
C2.23.78
The sun withdrew, its shining face concealed;Night spread its skirts across the open field.
C2.23.79
It was the hour when all the world lay still,And what was seen grew hidden, field and hill.
C2.23.80
When night led armies over hill and height,The sun that lit the world withdrew its light.
C2.23.81
To pierce the pitch-black darkness, keen and bright,She lit the blaze that scorched the eyes of night.
C2.23.82
A brazen tabira in her heart beat clear:“Now steel-hoofed Rakhsh is coming; he draws near!”
