Direct evidence of ancient Bronze Age drug use found in Menorca
Human consumption of mind-altering substances can be traced in the archaeological record back to prehistoric times; however, this is based on indirect evidence such as the typology and function of certain artefacts related to their preparation or consumption.
Menorca was first inhabited during the second half of the third millennium BC during the Late Copper Age/Early Bronze Age.
The islanders constructed large megalithic stone monuments known as navetes, taules and talaiots. Around 1450 BC, a tradition emerged using natural caves closed off with cyclopean walls for human burials.
A new study published in the journal scientific reports, has found direct evidence of drug use in Bronze Age Menorca, based on an analysis conducted on human hair found in the cult cave of Es Càrritx, in Menorca (Balearic Islands).
Archaeologists excavating the cave found a Bronze Age burial, where strands of human hair were recovered that were used in a singular funerary rite.
A chemical analysis performed on the hair using Ultra-High-Performance Liquid Chromatography-High Resolution Mass Spectrometry (UHPLC-HRMS), has detected traces of alkaloids ephedrine, atropine and scopolamine, confirming the use of different alkaloid-bearing plants by the inhabitants of Bronze Age Menorca around 3,000-years-ago.
According to the study, the flora native to Menorca includes the psychoactive species: Datura stramonium, Hyoscyamus albus and Mandragora automnalis, which contain the tropane derivatives atropine and scopolamine. Also on the island is Ephedra fragilis, which contains the phenylethylamine derivative ephedrine, and Papaver somniferum, which contains a variety of benzylisoquinoline alkaloids, morphine and papaverine.
The Bronze Age populations of Menorca may have employed drug plants for their medicinal properties, however, the high levels of toxicity found in the hair samples suggests that plant drugs were also used for the hallucinogenic properties in shamanic ceremonies.

A study of archaeological sites in Winchester, England, has revealed that red squirrels served as a host for Mycobacterium leprae strains that caused leprosy in people.
Leprosy is one of the oldest recorded diseases in human history and is still prevalent to this day in Asia, Africa, and South America.
It has previously been suggested that the extensive trade of red squirrel fur, greatly valued during medieval times, could have contributed to the leprosy epidemic in medieval Europe.
The results of the study, published in the journal Current Biology, studied 25 human and 12 squirrel samples from two medieval sites in Winchester.
During this period, the city had strong connections to the fur trade and housed the leprosarium, a hospital that treated people with Hansen’s disease (leprosy) caused by Mycobacterium leprae bacteria.
Verena Schuenemann of the University of Basel in Switzerland, said: “With our genetic analysis we were able to identify red squirrels as the first ancient animal host of leprosy.”
The study found that the medieval red squirrel strains were more closely related to human strains in Winchester, rather than to modern squirrel strains from England – suggesting an independent circulation of Mycobacterium leprae strains.
“Our findings highlight the importance of involving archaeological material, in particular animal remains, into studying the long-term zoonotic potential of this disease, as only a direct comparison of ancient human and animal strains allows reconstructions of potential transmission events across time,” says Sarah Inskip of the University of Leicester, UK, a co-author on the study.

Archaeologists from the Uncovering Roman Carlisle project have discovered a rare lump of Tyrian purple at the grounds of the Carlisle Cricket Club in Carlisle, England.
The project is a community supported excavation by Wardell Armstrong, focusing on uncovering a Roman bath house found in 2017.
The bath house is located near the Roman fort of Uxelodunum (meaning “high fort”), also known as Petriana, in the Carlisle district of Stanwix.
Uxelodunum was constructed to control the territories west of present-day Carlisle and an important crossing on the River Eden. The fort was garrisoned by the Ala Petriana, a 1,000-strong cavalry unit, whose members were all granted Roman citizenship for valour on the field.
Previous excavations at the bath house have discovered colossal sandstone heads depicting Roman gods, in addition to engraved gems known as intaglios, figurines, animal bones, and imperial-stamped tiles.
During the latest season of excavations, archaeologists found a mysterious lump of a soft purple substance. The substance was tested by researchers from Newcastle University, revealing that it contained levels of Bromine and beeswax.
According to the researchers, the substance is Tyrian purple, a coloured dye associated with the Imperial Court in the Roman Empire. Tyrian purple is secreted by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name Murex.
Frank Giecco, Technical Director at Wardell Armstrong, said: “For millennia, Tyrian Purple was the world’s most expensive and sought after colour. It’s presence in Carlisle combined with other evidence from the excavation all strengthens the hypothesis that the building was in some way associated with the Imperial Court of the Emperor Septimius Severus which was located in York and possibly relates to an Imperial visit to Carlisle.”
“It’s the only example we know of in Northern Europe – possibly the only example of a solid sample of the pigment in the form of unused paint pigment anywhere in the Roman Empire. Examples have been found of it in wall paintings (like in Pompeii) and some high status painted coffins from the Roman province of Egypt,” said Giecco.
