“But fifty times shall not rekindled be The countenance of the Lady who reigns here, Ere thou shalt know how heavy is that art”;
and those of Brunetto Latini, Inferno XV 61:—
“But that ungrateful and malignant people,
Which from Fiesole of old descended,
And smacks still of the mountain and the granite,
Will make itself, for thy good deeds, thy foe.”
