Read it through once

The speaker in the monologue is looking down upon Florence, in the valley beneath, from a villa on one of the surrounding heights. The startling bell-tower Giotto raised more than startles him. (For an explanation of this, see note under Stanza 2.) Although the poem presents a general survey of the old Florentine masters, the THEME of the poem is really Giotto, who received the affectionate homage of the Florentines, in his own day, and for whom the speaker has a special love. The poem leads up to the prophesied restoration of Freedom to Florence, the return of Art, that departed with her, and the completion of the Campanile, which will vindicate Giotto and Florence together, and crown the restoration of freedom to the city, and its liberation from the hated Austrian rule.
