A shield she had of more than Gorgon power,
And whom she would she could transform to stone,
Nor ever had it failed her till that hour:
She proves his form invincible alone,
And calls its force petrific on her own.
Amazed he sees the indurated train,
The callous tenants of the silent throne,
And all the marble subjects of their reign,
Inviolably hard, their breathless shape retain.
