 She was married to Nello Pannocchieschi, who is known to have been lord of that castle, "podestà" of Volterra and Lucca, captain of the Guelphs, in 1284 and lived until at least 1322.He shut up his wife in his castle, and had her murdered in 1297 by having her thrown out of a window, after having locked her up for a while in his castle, perhaps because of her supposed infidelity, perhaps because he desired to get rid of her to marry someone else.The story was made famous by Dante in the fifth canto of his "Purgatorio".
