Deconstructing an ancient Roman medicine

As promised earlier, here’s a little something on recent efforts to deconstruct an ancient Roman medicine. The short piece in The Plant Press which initially intrigued me eventually led to the website of the Institute for Preservation of Medical Traditions, a fascinating organization of which I was entirely ignorant. It has some more information and some photographs, and in an easier to handle form than the pdf you get The Plant Press in. It will do while I try to locate the published paper.

It seems that in 1974 a 2000-year-old Roman shipwreck was found off the coast of Tuscany. It the course of excavating it, various remains were recovered which pointed to the presence of a physician on board. Among these were a water-proof tin container with what looked like pills inside. In 2004, fragments of these reached Alain Touwaide and Antonella Appetiti at the Institute for Preservation of Medical Traditions, who started to analyze their organic and inorganic composition. They teamed up with geneticist Robert Fleischer of the Smithsonian to identify the botanical constituents of the tablets using the latest DNA fingerprinting technology.

First results seem to indicate that the tablets contained at least carrot, radish, parsley, celery, wild onion, and cabbage, that is, simple plants to be found in the garden. There was probably also yarrow and the more exotic hibiscus, possibly introduced in the Mediterranean area from Asia. Significantly, all the components of the pills identified so far (be they vegetal or inorganic) can be found in the ancient medical texts that the scholars in the Institute have been locating in manuscripts preserved in collections worldwide, transcribing and digitizing, studying and databasing for decades, all activities that contribute to the Institute’s program aimed at recovering the medical heritage of the ancient Mediterranean world.

This is apparently the first time that archaeological remains of ancient medicines have been found, let alone their ingredients identified.

Of cattle and people. And barley

Dienekes, a blogger who specializes in molecular anthropology, has a quick note today on a paper on the molecular genetics of cattle in Europe. The main story is one of distinction between North and South.

Apparently, the expansion of the dairy breeds have created, or largely maintained, a sharp genetic contrast of northern and southern Europe, which divides both France and Germany. It may be hypothesised that the northern landscapes, with large flat meadows, are suitable for large-scale farming with specialised dairy cattle (Niederungsvieh, lowland cattle), whilst the mixed-purpose or beef cattle (Höhenvieh, highland cattle) are better suited to the smaller farms and hilly regions of the south. However, it is also remarkable that in both France and Germany the bovine genetic boundary coincides with historic linguistic and cultural boundaries. In France, the Frankish invasion in the north created the difference between the northern langue d’oïl and the southern langue d’oc. The German language is still divided into the southern Hochdeutsch and northern Niederdeutsch dialects, which also correlates with the distribution of the Catholic and Protestant religions. On a larger scale, it is tempting to speculate that the difference between two types of European cattle reflects, and has even reinforced, the traditional and still visible contrast of Roman and Germanic Europe.

It doesn’t seem that the strong latitudinal genetic differentiation in cattle is matched by one in human populations. Here the pattern is much more gradual and clinal. ((Maybe there’s more interbreeding among human populations than between cattle breeds?)) However, there may be a similar “sharp genetic contrast of northern and southern Europe” (or at least between the Mediterranean and the rest of Europe) for barley. ((Yeah, I know it’s an old paper, but it’s the only map of barley genetic diversity in Europe I could find online at short notice. No doubt our readers will send in better examples.))

I’d dearly love to have the time to find out whether other livestock and crops show a similar pattern.
