Building on the Facino's foundation, he reconstructed a state that began to compare of that of his father, Gian Galeazzo Visconti, before it fell apart under his brother Giovanni's rule.

[1][10][11] However, despite the wealth, territory, and military strength that she had brought to him, Filippo grew averse to Beatrice, perhaps because of jealousy of her late husband's reputation, or her own political power, or her greater age, or that she bore no children, or his favoring of his mistress, the much younger Agnese del Maino.

[12] A jurist, Gasparino de' Grassi Castiglione, proclaimed Beatrice, the troubadour, and the handmaidens all guilty of adultery or its complicity, and sentenced them to death.

A book written by Carlo Tedaldi-Fores [it][14] inspired Vincenzo Bellini to write a two-act opera, Beatrice di Tenda, first performed on 16 March 1833 at the La Fenice in Venice.

In their revision of Bernardino Corio's history of Milan, Angelo Butti and Luigi Ferrario noted that contemporaries had differing opinions of Beatrice Lascaris di Tenda.

They wrote that Rainaldi and Fleury claimed that Beatrice plotted against her Visconti husband in conducting secret correspondence with the Bishop of Passau and the Earl of Oettingen, and that they sent ambassadors to the Emperor Sigismund.

Butti and Ferrario also wrote that Andrea Biglia, an Augustinian friar and Italian humanist, chronicled that Beatrice was already advanced in years, and could no longer attract her husband, nor offer the hope of children.
