Prospero Farinacci (1 November 1554 – 31 December 1618) was an Italian Renaissance jurist, lawyer and judge. His Praxis et Theorica Criminalis (Practice and Theory of Criminal Law) was the strongest influence on criminal law in Civil law countries until the Age of Enlightenment. Farinacci defended Beatrice Cenci who was accused of killing her father in the most famous criminal case of the time. As a judge he was known for his harsh sentencing.

Biography

The son of a Capitoline notary, Farinacci was born in Rome, in 1554. He studied law at La Sapienza in Rome, receiving his doctorate in 1567, at the early age of twenty-three. Prospero soon earned himself the reputation as an able advocate. In 1567, he became the general commissioner in the service of the Orsini family of Bracciano.1 He reached the height of his professional career as the Papal Datario (the officer of the Roman Curia who investigates candidates for papal benefices) under Pope Clement VIII (1592–1605). He went on to become Giureconsulto e Procuratore Fiscale della Camera Apostolica (Consulting Jurist and Tax Attorney for the papal Treasury) under Pope Paul V.

Along with this eminence, he was also a notoriously difficult character with quite a checkered private life. In 1570, he was imprisoned for an unknown crime.1 In 1582, he was stabbed in the face in a street fight, leaving him with a diagonal scar on the left cheek and a blind left eye. In 1584, he was jailed for the serious crime of bearing arms in public. Whilst he was a staunch prosecutor of sodomites, in 1595, he was himself accused of sodomy with Bernardino Rocchi, a sixteen-year-old page in the Palazzo Altemps, the house of his benefactor.1 He was excused of the crime by Pope Clement VIII, who famously made a pun on Farinacci's name (which alludes to "flour" in Italian) by claiming that "The flour is good, it's the bag that's bad."

Farinacci was perhaps most famous as the advocate in the scandalous trial for murder, actually patricide, of Beatrice Cenci and her relatives (1599), which ended in their gruesome public beheadings. He played a major role in the defense and although he was not able to save the girl, he did convince the pope to allow the youngest brother, Bernardo, to survive, invoking both the boy's young age and temporary mental infirmity as mitigating factors.

In 1600, Farinacci had a son with a prostitute called Cleria. Ludovico later joined the clergy and in the end, he became his father's sole heir.2 Prospero's portrait by Giuseppe Cesari can be found in the Museo nazionale di Castel Sant'Angelo.
