The trepanned skulls are among the most fascinating and mysterious testimonies of our ancestors’ medical and ritual practices. Trepanation—that is, the deliberate creation of an opening in the skull—is the oldest known surgical operation, with archaeological evidence dating back at least to the Neolithic.

1. Prehistoric Origins (c. 7000–5000 BCE)
The earliest traces of trepanation appear at sites belonging to the Cardial culture on the Mediterranean coast of Europe and in the plains of South America. Instruments, often made of flint or obsidian, were used to scrape or bore through the cranial vault. The precise reasons for these interventions remain unclear: scholars propose they treated trauma (fractures, hematomas), severe headaches, or neurological disorders, but also served magical-religious purposes—liberating an evil spirit or enabling communication with the afterlife.

2. Ancient and Classical Practices
Among the Egyptians, and later the Greeks and Romans, trepanation persisted alongside more systematic documentation. In the 5th century BCE, Hippocrates described various techniques (grafting, perforated trepan) and emphasized the surgeon’s skill. Survival rates appear relatively high for the time, as evidenced by healed bone margins on many exhumed skulls.

3. The “Renaissance” in the Middle Ages and Early Modern Period
In the Middle Ages, master surgeons carried on the art of trepanation—sometimes with little regard for hygiene. By the late 15th century, Ambroise Paré catalogued the instruments in use (hand-drills, crown trepans) and gave precise procedural descriptions. Despite these advances, the operation remained feared, with pain and infection still carrying a high risk of death.

4. Postmortem Trepanation: Rituals and Trophies
Alongside operations on living patients, many skulls bear openings made after death:

• Cult of the Skull and Funerary Ex-votos: In certain Neolithic and Celtic societies, deliberate postmortem markings symbolized the soul’s release or rebirth. The cavities could hold offerings.

• War Trophies: In the Gallo-Roman period and among various indigenous peoples (in Oceania and pre-Columbian Americas), enemy skulls were taken as trophies and sometimes modified for display. Postmortem trepanation eased removal of soft tissues and aided in bone preservation.

• Curiosity Cabinets and Medical Collections: From the 16th century onward, with the rise of anatomy, trepanned skulls were collected, studied, and even decorated, filling cabinets of curiosities and early medical schools.

5. Modern Legacy and Understanding
Today, CT scanning and paleopathology allow us to distinguish antemortem trepanations (showing bone healing) from postmortem ones. These studies enrich our knowledge of ancient beliefs, surgical skills, and perceptions of life, death, and the beyond. They also reveal the universality of the practice—from Siberia to the Americas, Mesopotamia to sub-Saharan Africa—showing humanity’s enduring impulse both to heal and to honor the dead.
