Taddeo Gaddi built me. I am old, Five centuries old. I plant my foot of stone Upon the Arno, as St. Michael's own Was planted on the dragon. Fold by fold Beneath me as it struggles. I behold Its glistening scales. Twice hath it overthrown My kindred and companions. Me alone It moveth not, but is by me controlled, I can remember when the Medici Were driven from Florence; longer still ago The final wars of Ghibelline and Guelf. Florence adorns me with her jewelry; And when I think that Michael Angelo Hath leaned on me, I glory in myself.
