D3.4.19
When that pure mother bore her shining boy,A herald told his grandfather with joy.
D3.4.20
Within the stable stood a lofty mare,Dun-coated, fit for battle, strong and fair.
D3.4.21
That very night she bore a foal of white,With lion’s chest and shanks both short and tight.
D3.4.22
The Caesar raised his head in joy to seeThis birth, a sign of fortune’s kind decree.
D3.4.23
At dawn he called the child into his sight,And dressed the mare in trappings rich and bright.
D3.4.24
He stroked its eyes and mane with gentle joy;The foal was of an age with Nahid’s boy.
