NOVA: You shopped daily?

JZ: No, once a week. We would go to little vegetable markets and we'd pick up bread and vegetables and sometimes frozen meats—that kind of thing.

NOVA: Any adventures with spiders or snakes?

JZ: Not really. A carpet viper did make its way into one of our supply tents and there were camel spiders all around—but, you know, when you start making noise and banging things around, they pretty much stay away.

NOVA: What was your favorite part of the expedition?

tea tent imageJZ: The most wonderful aspect of this is how remote it is from civilization. It's way out there in the desert. And there are beautiful sunsets. There are huge sand dunes and the Empty Quarter isn't far away and the Bedouin are very friendly. They were very hospitable and we'd get to sit around and drink a lot of coffee. It's a very romantic type of atmosphere. At night you can see all the stars. People used to bring telescopes. You could see the moons of Jupiter with binoculars—it was so clear. And when they'd turn the generator off, it was total silence. No one had ever experienced that kind of silence before. No cars, no people, no television, no electricity, no airplanes going overhead—none of that.

NOVA: What did the local people think of what you were doing?

local people imageJZ: Well, at first they were kind of suspicious. They didn't know what the heck archaeology was. But we got several people really interested and they actually started finding sites for us. Once they knew what we were after—we would train them—they would go out there and find sites for us. They became really interested.

NOVA: Has Shisur become something of a tourist destination?

JZ: Oh yeah. There are people there all the time from all over the world. Journalists, TV people, ordinary tourists. I heard they're going to put up a little hotel there and even a gas station. It's really incredible.

NOVA: You used a lot of high-tech tools on this expedition. What, in your opinion, are the most important new tools available to archaeologists?

JZ: Brains! (laughs) No, new tools are great, but they're just that—tools. You have to be able to understand new tools and how they might help you. But you also need old tools, like ancient manuscripts, the study of geology, the study of climate, the study of plants and animals and all that stuff. It's what we call the interdisciplinary approach to trying to figure out what ancient people did or didn't do.

NOVA: What's next?

JZ: Well, I'm actually going to Yemen in January. There are sites there that we suspect were also controlled by the Ubarites—which we think may have similar kinds of fortresses and buildings. Ron Blom is doing more remote sensing for us. And we've already got some of the images. We're going to try to find precisely how well these cities stand out, if there are water sources associated with them, if the springs are perennial, and if they have these ancient trade routes running across them—because we know there were routes running across there during medieval times. Now it's just a matter of getting out there and finding the ancient ones.
