2000-year-old Chariot Discovered Intact



News has been filtering out of Bulgaria since this weekend about a discovery of an intact chariot of the 2nd century B.C. in a tomb in Bulgaria. (Some reports say the chariot dates to the 2nd millenium B.C., but this appears to be in error). The ancient land of Thrace comprised much of what is today Bulgaria, northeastern Greece and European Turkey, but much about their culture is unknown, due largely to the dearth of written records. Many spectacular tombs have been discovered in Bulgaria in recent decades (the pic in the header is one such, of the 4th c. BC), of which this is only the latest. Although the wooden parts of the chariot had rotted away, its shape could be reconstructed based upon the iron fittings used in its construction. It apparently was pulled by three horses, had two wheels and a bronze roof, and the passenger rode in an iron seat.

Back Online!

My internet service has been restored, and there was much rejoicing.

I'll be posting some chunkier tidbits a bit later, but for now I'll tide you over with this classic column from the Straight Dope.

Technical Difficulties

My apologies for the lack of posts the last couple of days. My cable went out at home, and so I have no internet. Work has been very busy which has limited my ability to post. Once this is all straightened out I have a bunch of material ready to go. Soon!

More Bad Archaeology Reporting

This is a bit old, but I intended to make a brief comment on it as an example of how not to make archaeological findings accessible to the public. Discovery News posted an article on a recent British survey of caves in northern Britain. One of the results of the survey was that ancient humans did not randomly select caves to dwell in, but favored those with large entrances and deep passages, eastern or western aspects, and level areas in front.

So far, so good. Not terribly surprising perhaps, but there are differences in cave selectivity depending on region and the purposes for which the cave was used. I suspect the main goal of the project was simply to survey caves for evidence of occupation and then catalog them. The problem lies in the introductory 'grabber' paragraph:

House buyers today usually peruse properties with a checklist of desired features in mind. This aspect of human behavior has apparently not changed much over the millennia, according to a new study that found prehistoric cave dwellers in Britain did exactly the same thing when choosing their homes.

The study found no such thing. A 'checklist'? A checklist implies writing, which of course these prehistoric people did not have. We can say that they preferentially settled certain kinds of caves, but this says nothing about the selection process. For all we know, the local shaman took the omens and declared a particular cave propitious for settlement. I understand that the reporter was trying to phrase the findings in a way a layman would understand, but this was the wrong way to go about it.

Terrorist Targets, Tehran Try Tablet Tussle

The American Bar Association has posted a summary of a legal case currently making its way through the justice system, which presents many interesting aspects. In brief, here are the facts: Several Americans were among those injured in a series of terrorist bombings carried out by Hamas in 1997. They took Iran, as one of the backers of Hamas, to federal court. The Iranians didn't show up. Upon presenting their evidence for Iranian support for Hamas, the court ruled in their favor. They were awarded $423 million and change, $300 million of which were punitive damages. That's where things get interesting.

Given that Iran didn't even bother to send anyone to present its case, it's no surprise that they have no intention of paying the award. Collecting is a bit difficult when the United States doesn't even have diplomatic relations with the other country. In theory, the plaintiffs can petition the court to seize Iranian assets in the U.S., but there are precious little of those left. Most of what remains, such as the old Iranian embassy, is immune from seizure by international law.

But the plaintiffs have found some objects in the U.S. that may be accessible. The Oriental Institute of the University of Chicago (which has a very nice museum, by the way, I recommend a visit) has possession of 15,000 clay tablets recovered in 1923 from the ancient Persian capital at Persepolis, in Iran. The tablets were taken to the U.S. for conservation and study, but with the intention of eventually returning them to Iran. A number of the tablets have already been returned in past years. The plaintiffs are now trying to gain possession of these artifacts. The University of Chicago has argued in court that the tablets are immune from seizure under the Foreign Sovereignty Immunity Act. The plaintiffs, on their part, claim the tablets fall under an exemption in the FSIA regarding property "used for a commercial activity." They argued that the Oriental Institute has used the tablets in commercial activities (I don't have the details, but presumably the argument is that by publicizing the tablets, the Institute has benefitted financially from them).

The district court found against the Institute, saying that only Iran itself could assert sovereign immunity. At that point, Iran finally showed up in court. The district court recently rejected their motion for summary judgment, so now we're waiting for the plaintiffs to prepare their case that the tablets have been used in commercial activity.

The possible effects of a judgment in favor of the plaintiffs are wide-ranging. The tablets would presumably be sold off on the open market, breaking up the collection and limiting scholarly access to them. Furthermore, the plaintiffs have already targeted other tablet collections, and presumably other kinds of artwork held by public institutions, might be targeted particularly items on long-term loan. Exchanges of art or other objects between the U.S. and other countries may become more difficult if those countries come to worry that they may lose possession of those objects due to actions by U.S. courts. This is something to keep an eye on.

Interpreting DNA Evidence

Last week, I posted a link to a NYT article that discussed recent DNA studies of people and cattle in Italy. These studies found genetic similarities between current populations of both species in Italy and those in various regions of the Near East. This link was then interpreted as evidence that the ancient people known as the Etruscans arrived in Italy from the Near East (either directly or indirectly) sometime in the last three or four thousand years.

John Hawkes' has a post on his anthropology blog that examines another such attempt to use DNA evidence to reconstruct ancient migrations, this one published in Science. The results have been controversial, which has led to much scholarly back-and-forth. I thought this would be a salutary example of the dangers of overinterpreting DNA evidence. So what's the controversy?

For those wanting more detail, Hawkes ably sums up the issues involved, but in brief the evidence is this: DNA testing of people from North Africa found that they possess specific variations in their mitochondrial DNA similar to people living in the Near East. Based on the differences between these lineages and other mitochondrial DNA, we can estimate the time at which these groups branched off from their neighbors. In this case, the answer is about 45,000 years ago. The authors argue that this indicates that there was a migration into North Africa from the Levant around that time, displacing the earlier people that lived there. The date corresponds to the first peopling of Europe, and the authors suggest that both movements were part of the same pattern of migration.

Not so fast, say two other scholars. There are other ways for genes to move around. A later movement of peoples might have brought over these lineages. Or there might have been gradual diffusion of genes (via a series of short-distance interactions) instead of large-scale population movements. The archaeological evidence suggests that there was no large scale migration from Europe or the Near East into North Africa until much more recently, around 5000 BC.

For now, the evidence is insufficient to decide between the alternatives: 40,000 year-old mass migration? Slow diffusion? Recent mass migration? These are precisely the same problems that come into play in the Italian studies. Just because you share a common ancestry with someone 5000 years ago in the Near East doesn't mean that a bunch of people came over from the Near East at precisely that moment. There are lots of ways that genetic material can circulate.

Famous Fictional Archaeologists: Daniel Jackson



Born: July 8, 1965
Education: University of Chicago
Specialty: Egyptology, alien artifacts
Likes: Abydos, Sha-Re
Dislikes: violence, getting killed

Although ostensibly an Egyptologist, Daniel Jackson exhibits a strong case of Omniscient Archaeologist Syndrome. We find that he is fluent in 23 languages (including Spanish, Russian, Mandarin and German) and can almost instantly grasp texts written in most obscure alien dialects. His most famous decoding involved the symbols on the Stargate itself, which allowed its use as an interstellar portal.

We first see Daniel Jackson at a lecture in a large lecture hall (presumably in New York or Chicago), attempting to convince a group of stuffy archaeologists that the pyramids were not built by the Egyptians, but are much older. It is interesting that in the snippet of lecture we hear, Jackson provides not a shred of evidence for this contention. On the other hand, a fuddy-duddy archaeologist stands to ridicule Jackson for this belief. The argument he uses, it might interest the reader, is perfectly legitimate, in that the pyramid contains an inscription with Khufu's name (discovered by Sir Flinders Petrie in 1883, but only confirmed in 2001). It is not clear what response Jackson would make to this, as his lecture dissolves in the midst of his reply. Sure enough, his theories are verified by the discovery of the Stargate. However, I feel sympathy for his well-meaning interlocutor.

Jackson's interest in Egyptology derived from his parents, who worked for the Metropolitan Museum of Art in New York. In a tragic accident, both died while installing a new exhibit when they were crushed by a large stone sculpture. Haunted by the event, Daniel briefly considered becoming an Egyptology-themed super hero ("The Mummy") before enrolling in the University of Chicago and following a more conventional academic career.

Hint for young archaeologists: hone up on your marksmanship and spacecraft piloting skills. You never know when you might be scooped up by a super-secret Air Force program combining archaeology and travel to different planets.
