Zarir Before Caesar, Goshtasb Silent

From C5.17, Zarir Bears Word to Caesar. It illustrates C5.17.20–28:

C5.17.20
When he arrived within the Caesar’s court,The chamberlain saw him and gave a report.
C5.17.21
Within the palace Caesar sat in gloom,With Kalus and Goshtasb in the room.
C5.17.22
The Caesar heard and let Zarir draw near;Goshtasb’s heart grew glad to see him here.
C5.17.23
Zarir came in, a cypress, straight and tall,And sat upon a throne within the hall.
C5.17.24
He hailed the Caesar, and due praise he paid,And honored all the Romans there arrayed.
C5.17.25
Then Caesar said, “You slight Farrokhzad here,And heed no rule of courtesy or fear.”
C5.17.26
Zarir replied, “This slave at last grew tiredOf all the service that his shah required.
C5.17.27
He fled the royal court to reach your land,And now enjoys high rank at your command.”
C5.17.28
Goshtasb heard, but answered not a word,As though no thought of Iran in him stirred.
