In her 46 years she bore eight children and buried three husbands. She was painted by Botticelli, slandered by Machiavelli, and feted by Pope Sixtus IV. She was celebrated as a warrior who fearlessly led her own troops into battle, and ruthlessly defended her city-state of Forli, but Caterina was eventually defeated, imprisoned and raped by Cesare Borgia.
Remembered as the author of a recipe book that went through more than 100 editions, Caterina was honoured at her death as 'without a doubt the first lady of Italy'. Her youngest son would become - like her - a brilliant soldier and a national hero, and the next four generations of her descendants would include two Dukes of Tuscany, a queen of France, and a queen of England.
