See an Alarmingly Well-Preserved Human Head in a Jar at This Portuguese University:-by Rafaela Ferraz

Though he died in 1841, Diogo Alves continues to serve face.

THE FIRST THING YOU’LL NOTICE upon entering the anatomical theatre at the University of Lisbon’s Faculty of Medicine is the lone pickled head, up on a shelf next to a diaphonized hand. It’s yellow, peaceful-looking, and somewhat akin to a potato. The various physicians and anatomy technicians in the preceding hallway all address it with a mix of familiarity and indifference. It’s just there, really. Just the head of Diogo Alves, whose claims to fame include being both Portugal’s first serial killer and the last man to be hanged.

At least one half of each claim is true.

Diogo Alves was born in Galicia in 1810 and traveled to Lisbon early in his life, to serve in the houses of the well-to-do of the Portuguese capital. This southwards migration was common to plenty of Galicians looking for work, but Alves soon realized a life of crime would be more profitable. (History often blames an opportunistic barmaid for this shift in morality, because what’s a story without a temptress?) From 1836 to 1839, he transferred his workplace to the Aqueduto das Águas Livres (Aqueduct of the Free Waters). Nearly one kilometer (0.62 miles) long, the Aqueduto spanned the Alcântara valley, allowing both water and suburbanites to make their way into the city, 213 feet above the rural landscape.

Having retired from the Aqueduto, Alves set his sights on flightier targets, formed a gang, and started targeting private residences. Eventually, after breaking into a physician’s house and murdering the people inside, he was caught by the authorities and sentenced to hang in February 1841.

This is where the facts of Alves’ story often go astray. He was not the last man to be executed—at least six more followed him to the gallows between 1842 and 1845. Portugal would eventually rule out capital punishment in 1867. And there is yet more to debunk. Alves was a serial killer, indeed, but not the first. The title falls to Luísa de Jesus, a Coimbra resident who confessed to the murder of 28 newborns taken from the local foundling wheel. She was hanged in 1772, the last ever woman to be executed in the country. As someone whose criminal career began and ended with a national milestone, Luísa de Jesus is the person Diogo Alves would have been, had his claims to fame held out. So why is his head the one on display?

Alves was executed in 1841, as phrenology was just beginning to rear its ugly head in Portugal. We recognize phrenology, the discipline developed by German physician Franz Joseph Gall in the 1700s, as a pseudoscience today, but back then its premises were simple and its conclusions downright revolutionary: the brain housed all aspects of an individual’s personality in physically distinct areas, and the shape of the skull reflected this internal organization. Personality traits, criminal propensity included, could be felt, palpated and measured right on the individual’s skull. It is no surprise, then, that a notoriously wicked corpse would draw the attention of Portugal’s budding band of phrenologists—who requested Alves’ head be severed and preserved for posterity, so the source of his criminal urges could be studied in depth.

There is little evidence that such a study of Alves’ personality ever took place in the University, though similar ones did. The skull of Francisco Mattos Lobo, a contemporary of his who butchered a family of four and defenestrated their dog, was examined by phrenologists in April 1842 and rests just two doors down the hallway, in a glass case of patinaed skulls, that, it seems, do not get nearly as many visits as Alves himself.

He is the celebrity, after all. Along with the rest of the body, his head has even inspired a comic book, a fictionalized biography and novel, and the 1911 silent film Os Crimes de Diogo Alves (“The Crimes of Diogo Alves”)—a serious contender for yet another national title, that of Portugal’s first fictional film.
