Goshtasb Rides Alone for Rum

From C5.4, Goshtasb Sets Off for Rum. It illustrates C5.4.1–4:

C5.4.1
At night Goshtasb saddled Shabdiz the steed,His father’s horse, and bridled him with speed.
C5.4.2
He wore a Roman robe of golden thread,A homa plume upon his crowned head.
C5.4.3
He took gold coins and jewels for his need,Enough to serve him where his road might lead.
C5.4.4
He left Iran and turned toward Rum alone,To seek a path to kingship of his own.
