He also took part in the victorious battle of Parabiago against his other nephew, Lodrisio, who had set a mercenary army to capture Milan.

With an army of mercenaries from northern Europe, which he entrusted to the sons of his brother Stefano, he expanded the duchy, capturing Pisa and buying Parma from Obizzo III d'Este.

Luchino Visconti was a patron of both music[6] and literature, having invited Petrarch to Milan.

[7] He married three times: to Violante of Saluzzo, daughter of Thomas I of Saluzzo, then to Caterina Spinola, daughter of Obizzo Spinola, and, in 1349, to Isabella Fieschi, niece of Pope Adrian V, who gave Luchino Visconti his sole legitimate son, Luchino Novello, although others of the Visconti later disputed his parentage.

[5] In January 1349 he discovered Isabella's unfaithful behaviour, and announced for her a terrible punishment.
