In part one of this article I examined a claim that the
biblical city of Sodom had been destroyed by an exploding meteor. Part one mostly reviewed the surprisingly negative response from biblical literalists.
In part two, I would like to survey the physical evidence presented to
support the explosive claim.
Explosive Evidence
The claim was put forward in a paper
presented at the 2018 annual meeting of the American Schools of Oriental
Research (ASOR). The paper’s authors were a team composed of excavators at
the Tall el-Hammam site along with researchers from the Comet Research
Group. The physical evidence presented in the paper was collected
from the dig at Tall el-Hammam, claimed to be the site of biblical Sodom.
The paper presented at ASOR begins by noting that many archaeological sites
in the Jordan plain north of the Dead Sea were abandoned in the Middle Bronze period (2000-1500 BCE) and remained unoccupied for centuries. The authors propose an exploding
meteor as the explanation for the sudden end of the Middle Bronze Age civilization in
that region.
Four main pieces of physical evidence were put forward:
- Concussive evidence: Only stone foundations remain; the mudbrick superstructures are mostly missing. Very few intact pieces of pottery were found.
- Directional evidence: Where tumbled mudbrick walls were found, they were northeast of the stone foundations. Pottery fragments were scattered in a northeasterly direction.
- Chemical evidence: A salt and sulphate content of 6% in the ash layer marking the city’s destruction in the Middle Bronze Age. The chemical composition of the salts is virtually identical to that of Dead Sea water.
- Thermal evidence: A small portion of pottery sherds are partially melted (“vitrified”) on the surface, indicating an exposure to temperatures between 8000° C and 12,000° C for less than a few milliseconds. A “melt rock” composed of melted and fused quartz and sandstone was found at another site 8.5 km away.
Examining the Evidence
Barring analysis from an expert, I can only share my own
thoughts.
Inhabited mudbrick structures need constant upkeep and
will quickly deteriorate once they are abandoned. After all, the bricks are
just dried mud. Only mudbricks that have been buried since their last use and
thus protected from the elements will be uncovered on an archaeological dig. Archaeologists
rely on stone foundations to tell them where mudbrick walls once existed.
Therefore, an absence of mudbrick structures at Hammam is not at all unusual.
Similarly, unbroken pottery is more the exception than
the rule at a dig. Only in an undisturbed burial context should you reasonably
expect to find intact pots.
With respect to the directionality of the found remains
for mudbrick and pottery fragments, maybe that had something to do with the
prevailing wind direction for the area in ancient times. A steady wind off the
Dead Sea could have blown debris material towards the northeast. Blown debris
covering fallen mud bricks in the northeastern sections of the site would have
preserved them from eroding away.
Wind blowing off the Dead Sea may have also had something
to do with the concentration of salt and sulphates. These were found in the ash
layer marking the end of the site’s Middle Bronze occupation. The site was
unoccupied for six or seven centuries until the Iron Age. Core samples indicate
that during the Middle Bronze the water level of the Dead Sea had fallen and
the south basin was entirely dried up until around 1500 BCE. Over that time,
salts blown off a desiccated Dead Sea could have accumulated in high
concentrations just offshore.
The vitrified potsherds seem like the strongest pieces of
evidence for something unusual. Middle Bronze pots were fired at low
temperatures of around 800° C. They may not
have had the technology to fire a pot hot enough to glaze it. But maybe they
did. Had there been a flash thermal event of 8000° to 12,000° C,
it seems to me that much more than just a few pieces of vitrified pottery would
have been found. Sand anywhere in the vicinity should also have been turned the
glass. Lightning is known to vitrify sand, soil, and rocks into fulgurite, so imagine what a thermal event such as what was proposed would have done.
The “melt rock” was a surface-level find, so who knows
where and when it came from.
The paper goes on to identifier several typical markers
of an airburst event. I’m not convinced that an aerial burst would generate
those kinds of markers, but the point is moot because the authors go on to admit that preliminary analysis reveals some
of these markers at the Hammam site, “but not at compelling levels.” If it’s
not compelling to them, it’s certainly ain’t compelling to me.
Evidence Demands a Verdict
One thing not mentioned by the article involves the
conditions at other sites in the area. The Bible states that Sodom was only one
of the “cities of the plain”. In addition to Sodom, there’s the well-known
sister site of Gomorrah and the less-known cities of Admah and Zeboiim. Being
the largest ruin in the area, Tall el-Hammam is supposedly the main city of
Sodom and the neighboring Tall Kafrayn is assumed to be Gomorrah. Tall Nimrin
is proposed as Admah and other sites for Zeboiim.
If a meteoritic airburst took out Sodom, it would have
affected the neighboring cities as well. I reviewed the papers from the teams
excavating Tall Kafrayn and Tall Nimrin and nothing out of the ordinary was
mentioned there. Maybe I missed it. Or maybe the teams exploring those sites
failed to spot salt haze and vitrified potsherds.
Where does this leave us? The physical evidence proposed
for a meteoritic airburst hardly seems conclusive. There are simpler alternate
explanations that come to my mind. I would think that an expert in the field
would be able to suggest more likely explanations than what I was able to come
up with. We would also need to see evidence from other sites in the Jordan
plain, not just Tall el-Hammam.
I am sympathetic to the airburst theory. A major
catastrophe like that would be remembered for centuries and handed down in
legends. It would be cool if it were true. But based on the physical evidence
presented, I have to conclude that it is not. Or at best, not proven.
Tall el-Hammam may have been the biblical city once known
as Sodom, but that doesn’t mean it was destroyed by an exploding meteor.
