Kavus's Palaces on Mount Alborz

From B6.8, Kavus Sets the World in Order. It illustrates B6.8.11–21:

B6.8.11
Upon Mount Alborz he prepared a height,Where weary Divs were spent beneath his might.
B6.8.12
Two houses there of hardest stone were made,Their massive forms in ordered measure laid.
B6.8.13
Each measured ten kamands across its span,Raised firm in stone according to his plan.
B6.8.14
He carved stone stables in the mountain’s side,With pillars set and steel nails deep applied.
B6.8.15
War-steeds stood there, and camels for the way,To bear the royal ammari day by day.
B6.8.16
He built a palace fashioned all of glass,Its walls with emeralds set in shining mass.
B6.8.17
A dome of onyx crowned the structure high,Brought far from Yemen under southern sky.
B6.8.18
A famed Mobad was seated in that place,Where knowledge never waned or lost its grace.
B6.8.19
Two silver armories were built beside,With weapons for the royal wars supplied.
B6.8.20
A golden hall for Kavus rose, ornate,Two shast in height, its measured walls stood straight.
B6.8.21
With turquoise tracery the walls were dressed,And rubies burned from every arch and crest.
