Riddle 61

The banners were waving, gems glittered and shone,
When my first and my second ascended the throne,
And peacefully reigned with a merciful sway
In glory and splendor. But one summer day
A message was brought to the court and the state
That the king was not coming, the session must wait.
A great consternation o’er all faces spread;
They whispered in sorrow, “Alack for his head!”
And the courtiers echoed, “Alas for his poll!
Oh, who can now help him, his head is my whole!”
