Eighteen of 46 ancient Egyptian skulls show fractures from blunt force trauma. That’s strong new evidence that some people buried alongside early Egyptian royalty were killed on purpose to serve their rulers in the afterlife, a practice scholars call “retainer sacrifice.” According to Ars Technica, bioarchaeologist Roselyn Campbell re-examined crania first dug up more than a century ago by the pioneering Egyptologist Flinders Petrie. She found injuries that Petrie had seen but couldn’t read.
What stands out here isn’t new excavation. It’s new eyes on old evidence.
🔍 What the Researchers Did
Campbell went back to the 46 skulls Petrie recovered and checked four things:
- Age and sex of each individual
- General health markers visible on the bone
- Signs of injury and when those injuries happened
- Clues about cause of death
Her sex estimates mostly matched Petrie’s. She’s careful about that, though. Skulls alone can’t settle the question, and you’d need pelvic bones to be sure. Matching the rest of the skeletons back to their skulls after a century would be “extremely difficult,” even with the time and money to re-excavate.
📊 The Key Numbers
- 46 skulls examined
- 18 with linear fractures, about 39 percent
- Several with sharp-force trauma, including chop marks near one eye socket
Linear fractures like these point to blunt force trauma. Per Campbell, a blow like that would have knocked the person unconscious and caused internal bleeding, and likely death.
The other 28 skulls don’t show clear fatal injuries. Scholars have suggested those people may have died by asphyxiation, strangulation, or poisoning, which wouldn’t necessarily leave marks on the skull.
🦴 Why Petrie Missed It
Petrie didn’t record any fatal trauma. Campbell doesn’t blame sloppy work. “I don’t think he missed them because he was a pretty careful observer,” she told Ars Technica. “He just didn’t know what he was looking at.”
The difference is a few decades of forensic research into how bone breaks. Fresh bone, dry bone, and bone hit by different kinds of force all fracture in distinct ways. “If you don’t know that a bone is going to break differently if it’s 100 years old versus 1,000 years old versus 6 days old, you would see a crack and go, ‘Oh, well, it probably happened during excavation,'” Campbell said. “That’s not uncommon, unfortunately.”
So a crack that once looked like damage from the dig now reads as an injury from around the time of death.
🪵 What the Weapon Probably Was
Egyptian art often shows rulers smiting enemies with a mace. The fractures don’t fit that picture. A mace leaves depressed fractures, where the bone gets pushed inward. These skulls show linear cracks instead, which points to something flat, wide, and lighter.
“It could be as simple as a board,” Campbell said. Petrie thought it might have been a sandbag. Campbell doubts it, since swinging a heavy sandbag would probably do more damage. Her best guess is some kind of improvised wooden club. “People use makeshift weapons all the time.”
⚠️ Limitations Worth Noting
Campbell is upfront about what this study can and can’t show:
- Sex estimates are tentative without pelvic bones.
- The weapon is unknown. The fracture pattern narrows it down but doesn’t identify it.
- Most individuals show no clear cause of death, so the 39 percent figure is a floor, not the full story.
- Skulls and bodies can’t easily be reunited after a century apart.
💡 Why It Matters Beyond Egyptology
This is significant because it shows how much value is still sitting in old collections. Nobody dug anything new up. One researcher applied modern forensic knowledge to material that had been on record for over 100 years, and that turned a long-running debate about retainer sacrifice into something much closer to physical proof.
It’s a lesson for any field that works with legacy data. Labels and conclusions from earlier work reflect what people knew at the time. Petrie’s “probably excavation damage” was a fair call in his day, and it was wrong. Researchers in any discipline should expect some of today’s “noise” in their data to turn out to be signal once better methods come along.
Expect more re-examinations like this one as forensic techniques keep improving. Museum storerooms are full of remains that early excavators described as best they could. The full details of Campbell’s work are available at Ars Technica.
