"Ah, when thou hast returned unto the world,
And rested thee from thy long journeying,"
After the second followed the third spirit,
"Do thou remember me who am the Pia;
Siena made me, unmade me Maremma;
He knoweth it, who had encircled first,
Espousing me, my finger with his gem."
Purgatory, V, 130-36.
