At last Cane della Scala made a sort of alliance with his rivals, and having got the mastery in several other cities, installed Marsilio Carrara in Padua as his lieutenant and representative. Had Cane della Scala lived this might have worked well enough; on his unexpected death, his sons began to contrive how they should get rid of Marsilio; but they lacked skill and decision, and could neither conceal their intentions nor agree upon definite action. To make matters worse, one of them, Alberto della Scala, became madly enamoured of the wife of Albertino Carrara, and when every means failed to seduce her, took her to himself by brutal violence. After this outrage, the thirst for vengeance drove the Carrara further than mere ambition could have done. The crimes of the Scala, no less than their miserable weakness in all political matters, had excited the profound resentment of Venice, of Florence, of Lucca, and of the Gonzaga and Este families; war was declared, and it was not long before the lords of Padua were reduced to extremities. Though they had always maintained a haughty bearing towards Venice, they now attempted a reconciliation, and chose as their intermediary Marsilio di Carrara, whom they believed to be a traitor to his own family and devoted to their interests, and for whom the Republic had always shown a certain partiality, appreciating him, no doubt, at his true value, and anticipating the time when he might be useful. But Marsilio, like every other Carrara, dreamt only of revenge upon the Scala. At a great public spectacle he was seated by the Doge. ‘What will you give,’ he asked in a quick whisper, ‘to him who places Padua in your hands?’ ‘The city itself,’ answered Francesco Dandolo without the slightest hesitation. The unsigned treaty of betrayal was agreed upon in those few whispered words, and was executed to the letter and at once. Padua was taken by the Venetians and handed over to the Carrara under a sort of agreement from which each of the allies derived some advantage, and there was an exchange of high-flown speeches, amongst which that of the Venetian Loredano recommended the most serene Republic’s new favourites to behave with great goodness to her subjects, and to exhibit much gratitude towards her. On his side Marsilio begged that her ‘kind offices’ might be continued to him and his. The consequences of this treaty were soon clear. Venice nominally gave Padua over to the Carrara in order to obtain the annexation of Treviso, which was much more important to her, and Alberto della Scala was not set at liberty till he had ceded the latter city to the Republic. At the death of Francesco Dandolo, one naval battle lost to the Genoese represented Venice’s loss during the reign; her gain was an extension of territory of immense value; the whole result was to involve the Republic in intrigues which very nearly led to her destruction.
