X-ray Vision for Archaeologists: The “Multi-PAM” Tool

Being able to clearly see what lies underground would solve many headaches for archaeologists.

There is a certain level of guesswork that goes into planning a dig, and only after the available time, money, and manpower has been spent does it become clear whether or not it was worth the investment. However, a professor at Tel Aviv University has developed a new tool that potentially could offer some help in taking the guesswork out of deciding where to dig.

Reported recently in the journal Advances of Geosciences, Prof. Eppelbaum’s new tool gathers data from a number of sources — including radio transmitters used to communicate with nuclear submarines and detailed magnetic field observations — and applies an original algorithmic approach to the measurements to make sense of what lies below the earth’s surface at depths of up to several dozen yards. His tool can help people “see” meaningful objects, artefacts or civilizations — – and lay them out in a four-dimensional chart.

While methods exist for scanning sites of potential archaeological and geological importance, such tools produce significant background noise or inconclusive readings, Prof. Eppelbaum says. …

His tool can be used to evaluate the possible archaeological significance of any given area under scrutiny. Providing rapid results within days or even hours, the algorithm can “read” extensive data before any digging or exploration begins. Financially, technically and ecologically, this tool offers an optimal way to localize and classify ancient buried objects and estimate the potential of the further archaeological investigations, he says.

Prof. Eppelbaum’s solution is called the “multi-PAM,” which stands for “physical — archaeological models.” The tool first interprets what it “sees” by recognizing image targets; then the interpretation can be used to develop a four-dimensional model which can be presented to archaeologists hoping to explore a particular region.

Placed in a small unmanned airplane hovering several yards off the ground and scanning wide tracts of land along the earth’s surface, Prof. Eppelbaum says, the tool can reveal unexplored sites of historical and archaeological significance.

According to one of the posts, this tool is already in use in some archaeological projects. Does anyone have any personal experience with one? Would you care to share your opinion?

Update:
The catalyst for this news event apparently was a post on the website of the American Friends of Tel Aviv University. This post looks back at the publication of a paper that Prof. Eppelbaum presented in April 2009. The paper is titled: “Archaeological geophysics in Israel: past, present and future.” This paper (along with several others on similar topics) was published in the open access journal called Advances in Geosciences (ADGEO) in 2010. The abstract of Eppelbaum’s paper and a link to download the article can be found here. A list of all the articles in that volume can be found here. For those who desire to learn more about modern techniques for non-intrusive archaeological investigation, this volume is a good place to start.

Canaanite Water Tunnel at Gezer

The Baptist Press recently posted an article about the Middle Bronze II water tunnel at Tel Gezer. The excavation team is currently clearing out the tunnel and conducting a detailed study of it. Below is a picture of the entrance to the tunnel taken in 2004 by Todd Bolen. The tunnel begins to the left of where the man is standing and descends underground past the left side of the picture. (Recent pictures from inside the tunnel are posted with The Baptist Press article.)

Here’s how the article describes the tunnel:

The challenge is excavating a large, rock-hewn water tunnel at Tel Gezer that is believed to have been carved out by Canaanites between 1800 and 1500 B.C. — around the time of Abraham. Tons of debris must be removed from the ancient tunnel before the real work can even begin. …

The Gezer system also is unusually large, measuring 12 feet wide by 24 feet tall, Parker noted. It is believed that the ancient people used donkeys to ferry water from the source to the surface. The width allowed two animals, loaded with jugs, to pass side by side. The height of the tunnel perplexes the expedition team, and they hope to find an explanation as they pursue the dig. …

Last summer the team began the arduous tasks of removing tons of rubble from the tunnel. During a three-week dig, they cleared 72 tons of dirt and rocks. Team members dug out the tunnel and put debris in large sacks which were hoisted out with a crane. Due to the 38-degree slope, Parker compared it to working on a steeply pitched roof.

The Middle Bronze II period was a time when the Canaanite city-states grew strong. Large public works were widespread in the region, such as city walls, massive earthen ramparts, and glacis (i.e., defensive slopes below the city walls). So the cooperation and organization needed to dig a water tunnel was relatively common during that period, but (as the article points out) elaborate water systems were not. Sophisticated water systems (such as the ones at Hazor, Megiddo, and Hezekiah’s Tunnel in Jerusalem) are more characteristic of Iron Age II cities.

Side Note: The article mentions that 1800 to 1500 B.C. is “around the time of Abraham.” The date of Abraham’s lifetime is a debated issue related to the “Early Date vs. Late Date” controversy about the Exodus. The article apparently assumes a Late Date position. My personal conviction (and that of Todd Bolen) is that the Early Date position is the correct one, which would place Abraham’s lifetime at approximately 2150 to 2000 B.C. If this is correct, then construction of the Gezer water tunnel would have occurred during the time of Israel’s 430-year sojourn in Egypt.

Carchemish Renewed Excavations Draw Near

This isn’t exactly breaking news, but I did not find any other blogs that had written about it, and it seems worthy of mention.

Back in September 2007, Turkish Daily News (now known as The Hürriyet Daily News and Economic Review) reported that operations to clear the land mines near the site of Carchemish had commenced. At the time, it was estimated the clean-up would take about one-and-a-half years. Todd mentioned it here.

As a follow-up to this story, it was reported last December in Today’s Zaman that the mines had been cleared and the land was now in the process of being turned over to the city. After bidding for the mine-clearing project, work actually commenced in March 2010. Three hundred days later, it was complete. Mine-sniffing dogs were used in the initial stages, and to avoid damaging antiquities, the mines were removed to another location for detonation (usually, mines are detonated on the spot). Now that the mines have been cleared, archaeologists will begin “serious and long-term” excavations, which it is hoped will attract tourism.

The site of ancient Carchemish is cut by the modern Turkey-Syria border. The citadel and inner town are located within Turkey, but most of the outer town is located in Syria. On the Turkish side is the modern village of Karkamiş and on the Syrian side is the village of Jerablus. As part of Turkey’s attempts to open up trade with its neighbors, plans are underway to open three new border crossings with Syria by 2012, one of which will be located at Karkamiş.

For an account of the earlier excavations conducted by Sir Leonard Woolley, see here.

Byzantine Church Revealed at Khirbet Midras

A large public building that was turned into a church was recently excavated at Khirbet Midras in the Shephelah. The area was populated in the Second Temple period and is well known for a beautiful rolling stone tomb (since destroyed by vandals).

The archaeologists are suggesting that the church commemorated the burial place of the prophet Zechariah. Given that the sources for this appear to date nearly 1,000 years after Zechariah’s death (c. 500 BC), it may be best to regard this as a dubious Byzantine tradition. Some of the overstated wording of the IAA press release suggests that this claim is going to be the basis for reconstruction and promotion of the site. From the press release:

A public building of impressive beauty dating to the Byzantine period, in which there are several construction phases, was exposed in the excavation. In the last two construction phases the building was used as a splendid church. However, based on the results of the excavation and as evidenced by the artifacts, it seems that this church is built inside a large public compound from the Second Temple period and the Bar Kokhba uprising which was used in the first construction phases of the compound.
The church, in its last phases, was built as a basilica, at the front of which is a large flagstone courtyard from which worshippers passed into an entry corridor. Through a shaped opening one enters into the nave where there were eight breathtaking marble columns that bore magnificent capitals which were specially imported from Turkey. At the end of the nave is a raised bema and on either side of the nave are two wide aisles. All of the floors in the building were adorned with spectacular mosaic floors decorated with faunal and floral patterns and geometric designs that are extraordinarily well preserved. Located behind the bema are two rooms, one paved with a marble floor and the other that led to an underground tomb devoid of any finds. Branching out beneath the entire building is a subterranean hiding complex in which there are rooms, water installations, traps and store rooms. This complex belongs to the large building from the Second Temple period which the Byzantine church was built into. Among the artifacts discovered in the hiding complex are coins from the time of the Great Revolt (66-70 CE) and the Bar Kokhba uprising (132-135 CE), stone vessels, lamps and various pottery vessels that are characteristic of the Jewish population from the settlement at that time.
As previously mentioned, researchers who visited the site are of the opinion that this place is the residence and tomb of the prophet Zechariah. Ancient Christian sources identified the burial place of the prophet Zechariah in the village of Zechariah, and noted that his place of burial was discovered in 415 CE. The researchers believe that in light of an analysis of the Christian sources, including the Madaba Map, the church at Horbat Midras is a memorial church meant to mark the tomb of the prophet Zechariah. This subject will be examined and studied in the near future.
