Bones, Bruises, and the Medici: What Bioarchaeology Is Actually Unearthing

On 13 July 2026, a thread posted by writer Niko McCarty and amplified by Asimov Press argued, with the breezy certainty of a recruiter pitching a graduate programme, that bioarchaeology might be "the coolest field to work in today": biology research in nice places, ancient murders solved, history rewritten. The bait is the Medici. The story, like the bones, runs deeper.

Bioarchaeology is having a public moment, and the Medici are its most photogenic exhibit. A new wave of skeletal analysis is doing what documentary television has long pretended to do: re-examine the famous dead with instruments that did not exist the first time the story was told, and let the bones answer for themselves.

What a bioarchaeologist actually does

The field sits at the intersection of skeletal biology, archaeology, and forensic science. Practitioners recover human remains from archaeological contexts, then read them for age at death, sex, stature, diet, disease, trauma, and the mechanical signatures of habitual labour. The work draws on methods borrowed from forensic anthropology: trauma analysis to distinguish blade from blunt-force injury, paleopathology for chronic conditions such as tuberculosis or syphilis, and stable isotope analysis of tooth enamel to reconstruct childhood diet and migration.

The toolkit has grown more capable in the last two decades. Ancient DNA sequencing, once exotic and expensive, is now routine enough that the limiting factor is sample preservation rather than laboratory cost. Three-dimensional imaging, micro-CT scans, and isotope mass spectrometry let researchers interrogate a single skeleton without destroying it. The Medici investigation described by Asimov Press, like other recent high-profile cases, leans on these techniques: re-excavation under controlled conditions, multi-modal imaging, and isotope work to map diet, geography, and exposure to heavy metals across the life course. The point is not to confirm the older chronicle. The point is to test it.

The Medici murders, re-read

The story everyone has heard: in 1478, members of the Pazzi family attempted a coup against Lorenzo and Giuliano de' Medici during High Mass in Florence's Duomo. Giuliano was killed. Lorenzo escaped. The Medici response was swift and brutal. The conspirators were hunted down, hanged from the windows of the Palazzo della Signoria, and, in some accounts, thrown into the Arno. The chroniclers of the day were not neutral; they were patrons, partisans, or both. The story has been retold in paintings, operas, and novels for five and a half centuries.

What a fresh bioarchaeological pass can add is independence from the chronicle. Skeletal trauma consistent with multiple edged-weapon blows supports the accounts of Giuliano's death. Stable isotope signatures in the teeth of the hanged conspirators can be compared with the signatures of known Florentine residents to test whether the executed men really were locals, recent arrivals, or foreigners, a question the chronicles answer by reputation rather than evidence. Even the question of whether the bones in a given tomb are the bones a tomb is supposed to contain is, in practice, an empirical one. Tomb mis-attribution is more common than the tourist literature admits. Modern reanalysis routinely corrects it.

This is the move that distinguishes bioarchaeology from antiquarianism. The historian asks what the documents say. The bioarchaeologist asks what the documents miss, omit, or fabricate, and whether the bones will confirm or contradict the story.

Beyond the Medici

The Medici get the column inches because they are the Medici. The same methods are quietly transforming the study of less glamorous populations. Medieval and early modern plague cemeteries across Europe are being reopened, often in the teeth of local religious objections, to characterise the demographic profile of the dead. Were the 1348 Black Death victims disproportionately young adults, as some historians have argued, or did mortality cut across age groups in the way the more recent 1918 influenza pandemic did? The skeletons are the only evidence that does not depend on a scribe's habits. Stable isotope work on rural parish cemeteries is also redrawing the map of medieval migration, showing that people moved further, and more often, than the documentary record alone suggests.

Colonial-era mass burials in the Americas and the Caribbean are being re-examined with similar techniques, often by descendant communities rather than by European institutions. The politics of who gets to excavate whom is now part of the science, not separate from it. Forensic anthropology in the service of human rights investigations, in Argentina, in the Balkans, in Spain, is the public face of the discipline that the Medici glamour tends to obscure.

What the bones can and cannot tell you

It is worth being clear about the limits. A skeleton can usually establish age at death, biological sex, and a great deal about diet, disease, and mechanical loading. It can establish the presence of trauma and, often, the mechanism. It cannot, on its own, establish identity, intention, or motive. The Medici question is therefore not "can the bones tell us who killed whom," a question the documents already answer, but "can the bones confirm, complicate, or contradict the chronicle on the points where it is most self-serving." Sometimes the answer is yes, sometimes it is no, and sometimes the skeleton simply runs out of evidence.

There is also a question of context. A single skeleton pulled from a known tomb is, in a real sense, an n of one. Population-level claims, about migration, about diet, about the reach of the Black Death, require multiple burials, careful sampling, and statistical discipline. The press cycle tends to flatten this. A press release announcing that an individual was a "foreigner" because their isotopes differ from local norms is doing more work than the underlying chemistry can bear. Skilled practitioners know this. The headlines sometimes do not.

Why the field is growing now

Three things are happening at once. The cost of ancient DNA sequencing and isotope analysis has fallen. The number of trained practitioners has risen, fed by university programmes that did not exist twenty years ago. And the cultural appetite for re-examination of the historical record, particularly the record of institutions that wrote themselves the hero, has never been higher. The Medici project is a case study in the genre. So are the plague-cemetery re-excavations. So are the colonial-era burial projects. The bones have been in the ground the whole time. What is new is that the tools to read them, and the public willingness to accept what they say, have both arrived together.

Desk note: Monexus treated the Asimov Press framing as a hook into a wider field, rather than a profile of one lab. The Medici story is the most photogenic exhibit in a much larger excavation, and the sources do not warrant stronger claims about a single tomb than the evidence supports.
