Khosrow Warned at the Wine-Cup

From E5.26, Bahram’s Letter and Khosrow’s Flight. It illustrates E5.26.31–38:

E5.26.31
The son, still unaware of what was planned,Sat glorious in his palace, cup in hand.
E5.26.32
With charming idols and delightful wine,He passed his days, blind to the dark design.
E5.26.33
Two days each week he rode out to the chase,A brave young horseman, full of charm and grace.
E5.26.34
For God had willed that Khosrow’s crown should riseFor many years beyond the moonlit skies.
E5.26.35
A chamberlain caught wind of that dark deed,And cast aside both sleep and every need.
E5.26.36
He hurried to Khosrow and made it clear:The king was plotting murder out of fear.
E5.26.37
He learned the plot and fled that very night;He left Tisfoon and vanished out of sight.
E5.26.38
He saved his precious head and spurred his steedTo Azar Abadagan at great speed.
