Lucrezia Landriani (born c. 1440 â living 17 August 1507) was the mother of Caterina Sforza, Lady of Imola, Countess of Forlì. Lucrezia had three other children by the Duke, and two by her husband.
Around 1450 Lucrezia married Cristoforo Lampugnani, son of Lucrezia Visconti and Giovanni Andrea Lampugnani. Later, she married Count Gian Piero Landriani, a courtier at the ducal court and a close friend of Galeazzo Maria Sforza (24 January 1444 – 26 December 1476), son of Francesco Sforza, Duke of Milan and Bianca Maria Visconti, Duchess of Milan. Galeazzo Maria would become Duke of Milan upon the death of his father on 8 March 1466.
Lucrezia was born in Milan around 1440. A contemporary portrait of Lucrezia painted by Domenico Veneziano, shows her to have been quite beautiful, with blonde hair, blue eyes, a high forehead, and fine features. She bore her husband Gian Piero two children and undertook their guidance and education: a son, Piero Landriani, who later became castellan of the fortress of Forlimpopoli; and a daughter, Bianca Landriani, who married Tommaso Feo, castellan of Ravaldino Castle and the brother-in-law of Caterina Sforza.
