TUTANKHAMEN’S CT SCANS
In July of this year I mentioned
that I would discuss Tutankhamen’s CT scans in the next Hot Issues article but
I had to admit in August that Tom Friedman’s theory of the “Flat earth,” i.e.
unlimited instant access to information, applies only to some privileged people
rather than to most of the rest of us. Since I was unable to fulfill my promise
in August I wrote instead “The Plame Affair,” which has now become grist for
the mills of the mainstream media and TV pundits. I also mentioned in August
that I shall discuss the CT scans either when more definitive information has
become available or “it has become obvious that further waiting is fruitless.” This
is now the case. Although the drama which is currently unfolding in Washington
would deserve discussion this can wait until December.
In “The Saga of Tutankhamen’s Skull
X-Rays” (October 17, 2002) I presented in considerable detail the difficulties
we had encountered in obtaining a copy of the X-rays that had been taken in
1968 by a team from the University of Liverpool under the leadership of the
late Professor Harrison. The reason why I had persevered over a long period of
time was because the X-rays were purported to have shown a skull fracture
and/or subdural hematoma (blood clot on the brain). This in turn had given rise
to a widely reported theory that the pharaoh had been murdered by a blow to the
head.
After having had an opportunity to
study the actual X-rays, rather than photographs, upon which a book which
endorsed the murder theory had been written, my colleagues and I concluded that
the X-rays were normal, apart from post-mortem artifacts introduced by the
ancient embalmers as well as by the Carter-Derry autopsy in 1925. These
conclusions were published in The
American Journal of Neuroradiology in the June/July 2003 issue and this was
the first time that an assessment of these radiographs had been presented to
the medical community. Previous publications by Dr. Harrison had addressed
themselves to the general public or archeologists.
Although skull X-rays can
demonstrate bony changes they cannot determine possible soft tissue damage
which might be apparent on a CT scan. When I learned that Professor Griggs of Brigham
Young University
in nearby Provo had a license from
the Egyptian authorities not only to perform archeological excavations but also
DNA analyses on mummies with his colleague Professor Scott Woodward, I visited
with them. I was told that they had not only obtained samples from a large
grave site at El - Faiyum but they
had also been able to obtain some from royal mummies in the Cairo
museum in order to establish possible lineages within members of the XVIIIth
dynasty and they planned to examine Tutankhamen. I suggested immediately that when
the sarcophagus is opened for that purpose we ought to also obtain a CT scan to
settle the head injury question once and for all. This suggestion was well
received and I was asked to write a proposal to that effect because funding and
permissions would have to be obtained. I prepared a document that outlined the
need for the investigation as well as potential funding sources and submitted it
to Dr. Griggs on 0ctober 3, 1996. There was no reply but since the
archeological season in Egypt
is limited to the winter months he may have already been in Egypt
on other excavations. Nevertheless, the hope remained that we might get
something done for the next season. But although I kept calling Dr. Griggs over
the next few years on a regular basis nothing came of the attempt because there
were either other priorities or some hurdles from the Egyptian authorities.
Nevertheless, I was assured that the project was not dead it would just take a
little longer than what had been hoped for. After a while phone calls were no
longer returned and I issued a mental death certificate for it.
Then in the fall of 2001 the events
which are documented in the “Saga” took place and as mentioned the scientific
paper was published in 2003. At that point I thought I was done with Tut because
I felt that the political conditions in Egypt
simply were not conducive to good scientific work, especially since a scan
would have to be obtained at the tomb in the Valley of the Kings
because a transport to Cairo seemed
unrealistic. But January of this year brought to my great surprise the news
that a CT scan had been performed on the pharaoh’s mutilated remains under the
auspices of the Secretary General of Egypt’s
Supreme Council for Antiquities Dr. Zahi Hawass.
The early reports indicated that the
project had been funded by the National Geographic Society and Siemens of
Germany had made the scanner available, but as Dr. Hawass kept re-iterating the
actual work of data gathering and initial interpretation was all done by
Egyptians and only Egyptians. On March
8, 2005 there appeared the official Press Release where the world
was told that the scientific team, headed by Dr. Zahi Hawass, had reviewed over
17,000 images and that it had included radiologists, pathologists and
anatomists under the oversight of Dr. Madiha Khattab, Dean of Medicine at Cairo
University. Important aspects of
the report were that the team found no evidence to support a murder theory; the
king was about 19 years old at time of death; of slender stature about five and
a half feet tall; well nourished and in good general health. The slight
curvature of the spine that had been noted in Harrison’s
X-ray was within normal limits and had probably resulted from positioning at
the time of embalming. The missing sternum (breastbone) was probably the result
of Carter-Derry’s removal of the famous mask which had be firmly glued to the
body, rather than having resulted from a crushing injury to the chest as had
been posited by Dennis Forbes in 1992. The only disagreement among the
scientists was the nature of a fracture of the lower end of the left femur
(thighbone). Some regarded it as a wound that had occurred during life and
might have been a cause of death because open fractures would lead to infection
and blood poisoning which was untreatable in those days. Others felt that the
fracture was another post-mortem event and the question was not resolved.
So far so good but as usual the
devil is in the details and these already appear on the first page of the
report.
“Lead radiologist Dr. Marvat Shafik
and the rest of the team requested that three international experts, two from Italy
and one from Switzerland,
be permitted to review the images. ‘We need our opinion to be international,
since people all over the world are waiting for the results of this important
scan,’ said Dr. Shafik,”
But Dr. Hawass did not seem to be
enthused about international cooperation because the report goes on to state:
“Dr. Hawass also said: ‘The
Egyptian team worked on the images for two months. The foreign team came for
several days at the end to review the work of the Egyptian team. The foreign
consultants confirmed the results of the Egyptian team, and joined us to make
the announcement internationally. All of us are proud to announce these
findings, the first CT examination
of a securely identified royal mummy from ancient Egypt.
I believe these results will close
the case of Tutankhamun, and the king will not need to be examined again. We
should now leave him at rest. I am proud that this work was done, and done well,
by a completely Egyptian team.”
When we strip away exalted language
one gains the impression that the Europeans were not regarded by Dr. Hawass as
full partners in the assessment of the data but they may have been expected to
merely rubber stamp the findings of their Egyptian colleagues.
Inasmuch as Dr. Boyer and I had a
long standing interest in actually examining the CT scans rather than merely
taking somebody else’s word as to what they do or do not show a new chapter in
the Saga began. My main problem was that the report had not addressed itself to
two aspects of Derry’s findings. One was the nature of
the “rounded depression, which has slightly raised edges, the skin filling it,
resembling a scab” on the left check and the other the “pronounced bulging of
the left side of the occiput [back of the head].” In addition there was, of
course, the unresolved question of the possible left femur fracture.
The press release did provide the
names but not the addresses of the members of the Egyptian as well as European
team. There were 3 radiologists on the Egyptian team and 1 on the European. The
latter was Dr. Paul Gostner from Bolzano
Italy. But
every Austrian knows that Bolzano
used to be called Bozen, was the capital city of South Tyrol
and our esteemed President Wilson had handed the entire province to the
Italians after WWI. Self- determination of nations, as proclaimed in his 14
points, had its limits when it came to the vanquished ones. The Austrians of
South Tyrol were abandoned to the Italians and those of the Sudetenland
to the Czechs. Wilson’s motive was
to get his League of Nations approved by the Brits,
French and Italians regardless of the cost to actual people who suddenly lost
their homeland. This tit for tat was also part of the cause for WWII. There
were obviously bad feelings for some time between Austrians and Italians on
that score but these were overcome in subsequent decades and amiable
relationships exist now between the two countries.
At any rate, I felt a sudden sense of
kinship and the potential to get more information about the scans. I did not
have Dr. Gostner’s e-mail address but most of us have scientific articles to
our names and PubMed is one of the best examples of our tax dollars at work. It
is available to the general public and comes up immediately on search engines. Thereafter
one needs only the last name and the initial of the author and all the papers
arrive within milliseconds. The first paper on the list was authored by Dr W.
Murphy from Houston Texas
with the title: “The Iceman: Discovery and Imaging” and was published in Radiology in 2003. The abstract also had
Dr. Murphy’s e-mail address and he was kind enough to immediately supply me
with that of Dr. Gostner which led to a very fruitful correspondence. He told
me that he had read our report in the AJNR before going to Egypt
and it was fully vindicated by the CT results. A scientific publication of
their findings was planned but it needed the cooperation of the Egyptians which
was slow in forthcoming, and that he would be happy to collaborate with us in
any further data evaluation.
This took place at the end of June
and since Europeans have the good sense to get out of their hot cities during
the summer we postponed further discussions until the fall. In the meantime I thought
that since National Geographic had put up the money, and as a long time member
I had partially paid for that scan too, they should be able to put me in touch
with the Egyptians so that one might be able to expedite the situation
somewhat. I sent off an e-mail to the Magazine requesting the address of A.R.
Williams who had written “The New Face of King Tut His Life and Death” for the
June issue. Back came four pages of “Thank you for contacting the National
Geographic society …” and this was followed by links to frequently asked
questions which obviously were not related to my problem. But the message also
mentioned that questions which do not appear on the form would be answered
within two weeks. Lo and behold a week later the assistant to Ms Williams wrote
back stating that “The Society and Siemens have an explicit agreement with the
Supreme Council of Antiquities that the CT data is theirs to use as they see
fit. Thus all we can suggest is that you take your case directly to Dr. Hawass
and the SCA.” She then provided the contact information and an e-mail address.
This was on July 21 and the following day I wrote to Dr. Hawass explaining why
we would like to see the scans and offered any help in publication of the data,
that he might desire. The message did not come back as undeliverable but there
was no reply.
As a sailor I took another tack and
tried to establish contact with one of the Egyptian radiologists who had worked
on the scans. Dr. Essam Ismail, an Egyptian radiologist who currently works in Kuwait,
was very helpful in establishing contact with Dr. Ashraf Selim, Professor of
Radiology at Cairo University,
who was a member of the examining team. Dr. Selim wrote a very pleasant letter
back stating that he had also read our paper agreed with its conclusions and
“I'd love to communicate and share our knowledge.”
When I replied I mentioned not only
the reasons why we would be interested in seeing the scans but also that it
might have been useful to obtain DNA samples at the time of the scanning. Dr. Selim agreed that:
“DNA tests would have been definitely useful
for answering many questions but unfortunately we work under the supreme
council of antiquities who rejected this idea. . . . . Regarding the
issue of sending some of the CT pictures to you I personally agree
but I have to take the approval of Dr. Hawass first according to the
protocol of confidentiality that we signed with him before taking any further
steps.”
Since this still looked promising I
replied that “May be I could write to Dr. Hawass personally, if you think it
were to be useful.” The answer came back
immediately:
“Dear Dr. Rodin:
I really don’t think it's necessary now, let me contact him first and then we
decide what to do, regards.”
Well, it
doesn’t take much imagination to ascertain what happened here. The abrupt
change in tone clearly suggests that word came down from the top: “don’t get
involved with foreigners.” This
impression was confirmed in the subsequent correspondence with Dr. Gostner.
Earlier last month he told me that he and his two other colleagues had
repeatedly tried to continue the collaboration with the Egyptian scientists in
order to proceed with a publication but their efforts were thwarted. He also
told me that Dr. Frank Ruehli of Switzerland
(Anatomist and Paleopathologist, Zurich
University, and member of the
evaluation team) had suggested a presentation at the Anthropology Congress in
March 2006 and had sent a preliminary abstract for approval to Egypt.
After some delay he received this response from Dr. Hawass: “as a matter of
fact we can not make a kind of lecture in conference now. I am waiting to read
the first report of the two parties.” As Dr. Gostner mentioned to me it is
quite unclear what Dr. Hawass meant by this statement but it is apparent that a
publication or presentation is not in the immediate offing. All of us who have
submitted abstracts to national and international meetings know that there are
deadlines for when abstracts have to be received by the organizing committee
and these are usually at least six if not nine months prior to the meeting.
Thus any delay jeopardizes acceptance.
We have, therefore a situation that
is not readily understandable on scientific grounds. The European and the
Egyptian scientists are eager to collaborate further but apparently a political
decision has been reached to prevent this from coming to pass in the near
future. Dr. Hawass has currently the exclusive rights to the scans and for
reasons only known to him he apparently refuses to allow further studies. I
believe this attitude to be ill advised and would like him to reconsider his
stance.
Dr Hawass
has said in a recent speech that Tutankhamen “belongs to the world,” which is
true. Although everyone agrees that the artifacts found in the tomb as well as
the mummy belong to Egypt
this should not be extended to scientific data derived from them. The
scientific community is international and true scientists have only one goal,
which is to extract the maximum information from a given set of data. This is
why we have international societies for our various specialties and
international meetings where we can discuss in public as well as in private the
data we are most interested in.
Since I am
writing for the general public let me now explain why this international
collaboration is so vital. Let us be honest with each other; even if Dr. Hawass
were to give the Egyptian members of the team authority to publish a paper on
their own it would run into resistance from peer reviewers, if it were to be
submitted to a reputable international journal. They would immediately ask why
the European members of the team were not included and to what extent they
agreed with the conclusions that were expressed.
There is a further point. When one
has 17,000 pictures to review it is difficult if not impossible to do justice
to the data within a few days and that is all the time the members of the
European team had at their disposal. Furthermore, even in everyday clinical
practice we require a referral slip for a given examination. This may be for a
CT scan, an MRI or as in my case EEG/MEG which tells us what area we should pay
closest attention to. Digital technology has the tremendous advantage that the
data are stored as megabytes or gigabytes and these can be examined at leisure
from various points of view. Whenever I am not writing for general publication
I do just that with electrical and/or magnetic brain activity which was in part
collected several years ago. New observations are made with improved data
analysis programs and published. They can then point the way for better data
assessment in the future. But this takes time which overburdened clinicians
usually don’t have. On the other hand those of us who have reached retirement
age do have the time, know how and interest and are happy to pursue these
investigations for everybody’s benefit.
This brings
me back to Dr. Gostner and the iceman because it is an excellent example why
international collaboration is so vital. Oetzi, as he is affectionately called
because he was found in the Oetztaler Alps, was discovered in 1991 and has been
extensively investigated first by an Austrian and subsequently an Italian team.
Since there are no border guards on a glacier it was initially assumed that the
body was still on the Austrian side and it was taken to Innsbruck, but when it
was finally determined that that part of the glacier was already on the Italian
side of the border he was removed to Bolzano where he now resides in a special
museum. Although the Austrians did perform a CT scan no definitive cause of
death could be established. Since some of the ribs were “distorted” as if they
might have been fractured it was hypothesized that the man might have been
attacked, for some reason or another, escaped to higher altitudes and then
froze to death. A replica of his face, similar to that of Tutankhamen, was made
and the matter rested.
But Dr.
Peter Vanezis a forensic pathologist of Bolzano
did not. He was not happy with what had been called the “disaster theory” and
found that the body had not always lain in the position it was found. The ice
had apparently melted to some extent at some time and the body moved to a
slightly different location. When the water froze again the chest was partially
crushed which accounted for the deformed ribs. Thus, the disaster theory had to
be revisited and the cause of death was again undetermined. With this question
hanging in the air Dr. Eduard Ergarter Vigl, the curator of the mummy in Bolzano,
decided in June of 2001 it was time for another X-ray. This was done and the
films were given to Dr. Gostner, head of Radiology at Bolzano
General Hospital,
for evaluation. As soon as Dr. Gostner saw the chest X-ray he noted a foreign
body near the left shoulder. On close examination it was determined to have
been an arrow head and, therefore, a likely cause of death.
For the
Austrians this was major embarrassment. They had previously had the body for
several years, had performed a CT scan and had missed detecting that metal
fragment. Professor Horst Seidler from the University
of Vienna stated in a BBC interview:
“that has been the shock of my life.” Why had they overlooked the arrowhead in
the CT scan? Well, sometimes you can have too much information and the
proverbial needle in the haystack doesn’t jump out. When Dr. Wolfgang Recheis
loaded up the scans again on his work station in Innsbruck now knowing where to
look the object not only showed up clear as daylight but with further study and
newer data analysis tools the arrowhead could be completely reconstructed. This
is a perfect example for international cooperation how to get at the bottom of
a scientific problem. Oetzi had been shot in the left shoulder, escaped from
his pursuers to higher ground, pulled out the arrow, which was found in the
general vicinity, died of his wounds and the body froze.
Let us now
return to our Pharaoh and what should be done. The most obvious immediate
action should be to make the CT scans available to the European team so that a
preliminary scientific report on the data can be presented. There are so much
data on hand that the scans should subsequently be made available to qualified
specialists around the world upon their request. Different scientists have
different areas of interest and a series of papers, including a monograph,
could be published. This can readily be done and requires only the “go ahead”
from Dr. Hawass.
But a CT
scan can also give only a partial picture and more information might have been
obtained had a DNA sample been taken which opens another chapter of this Saga. In
response to Ms William’s report Ann Marie Ackermann of Boenningheim,
Germany wrote a Letter to
the Editor of National Geographic: “Although your article on King Tut was
fascinating, it contained an omission. Were any DNA samples taken and, if not,
why not?” The answer from the magazine was: “It is the policy of Egypt’s
Supreme Council of Antiquities not to do DNA testing on mummies. Some experts
believe such tests are not yet accurate enough for ancient remains and would
only open the door for speculation.
Although this is true it is not the
whole answer. Drs. Griggs and Woodward had, as mentioned above, obtained
samples even from pharaohs during the 1990s but for reasons beyond their
control never did get the go ahead to obtain samples from Tutankhamen. Furthermore,
when I reviewed Internet data for this article I found to my surprise that Carolyn
Hawley had reported from Cairo for
BBC News on November 11, 2000:
“Tutankhamun to undergo DNA tests.” The article stated in part
“A Japanese team, working with
local experts, will conduct DNA tests on Tutankhamun’s mummy, which has lain
undisturbed in its tomb in Luxor [sic] since it was last X-rayed in 1969 [sic].
The results will be compared with
tests on the mummy of the man thought to be his grandfather, Amenhotep III, now
in the Egyptian museum.
But mummy expert, Nasry Iskander,
cautions that DNA analysis on ancient remains is still a hit-and-miss affair
and that Tutankhamun’s mummy may be in too poor a shape to yield conclusive
answers.”
CNN.com reported on December 5, 2000 that a team of
Japanese experts was expected to arrive in Egypt
“this week” to obtain DNA samples. We don’t know at this time what happened but
apparently Dr. Iskander was overruled and the Japanese never got their samples.
This is a
very unfortunate situation. It is true that lineage may be difficult to
ascertain and that there are considerable technical problems. The difficulties
in regard to lineage are compounded in the case of royal mummies because, apart
from Tutankhamen, all have been removed from their tombs in antiquity and one
is working on bodies whose precise identity may be in doubt. This also applies to
the mummy of Amenhotep III. But lineage, important as it may be, is not the
only reason why an adequate DNA sample should have been obtained as mentioned
in my correspondence with Dr. Selim. The cause of the pharaoh’s death is
unknown and the skeletonized dismembered remains may not yield full answers in
regard to the cause of death but the viscera might provide additional
information. They were found by Carter in canopic jars in the tomb and
transported to Cairo at that time.
They ought to reside somewhere in the Cairo
museum. I am saying “ought” and “somewhere” because a physician, Dr. Bucaille,
who wrote a book for the general public in which he severely criticized
Carter’s handling of the mummy, stated that he could not find the canopic jars
in the museum. Thus even if someone were to look into the various nooks and
crannies of this vast building and were to find canopic jar contents labeled “Tutankhamun”
one would never know for sure whether these labels were indeed correct. If we
had DNA from the mummy, the contents of the jars might be properly identified
and one might be one step further in unraveling the mystery that surrounds the
young king’s unexpected death. Dr Hawass has been quoted in an interview on March 8, 2005 (MSNBC.com) as having
told the Associated Press: “I have two theories – that he may have died from
natural causes or that he was poisoned. We are going to look at the viscera to
see if his organs show any signs, but it is virtually impossible to prove how
he died.” I agree with the last part of
the last sentence but how is Dr. Hawass going to establish for certain, without
DNA confirmation, that the viscera really belonged to Tutankhamen?
Thus the
Saga continues. The last word has not been spoken with the Press Release and it
behooves us to find a way that allows proper scientific research of at least
the CT scans to proceed. But it is not only the fate of the CT scan that is at
stake. If Dr. Hawass were to insist that he has the right to control all
scientific publications resulting from excavations in Egypt
the entire field of Egyptology is in peril. This is why I wrote this article
and why I shall give it wide circulation. Inasmuch as I could not get a private
reply from Dr. Hawass I am now writing to him in public.
Dear Dr. Hawass
During the
past months I have made several attempts to contact you through private
channels but my efforts were unsuccessful. Since the topic is vital for the
current state of Egyptology I feel obliged to write to you in this forum. It
seems that the scientists who have evaluated the CT scans of Tutankhamen are
currently prevented from publishing their findings in the scientific
literature. I do not know the reason, but I do know that they are seriously
interested in doing so because Press Releases cannot do justice to the many
questions that are still unanswered.
As a first step I would like to
request that you make the entire set of scans available to all members of the
scientific team. This should be done electronically so that the scientists from
the different disciplines can independently investigate these scans at their
leisure rather than in a hurried manner. They can then discuss their agreements
and disagreements among themselves, arrive at sustainable conclusions and
publish the data. Thereafter a Symposium could be arranged at an appropriate
International Congress where the scientific community at large is given an
opportunity to see the data and review the conclusions derived from them. You
might want to give the keynote address at that Symposium. This is how science
proceeds in all other areas and the CT scan data should not be an exception. At
present the scans are of no benefit to anyone including you because they
require specialized expertise for further evaluation.
You have
recently received from the American University
in Cairo an Honorary Degree of
“Doctor of Humane Letters” and I appeal to you to regard this not only as an
honor but also as an obligation. You cannot shut out the international
scientific community because you depend on it for your future work. By not
releasing the scans you are not only hurting the scientific community at large
but also and especially your Egyptian co-workers who have spent a great deal of
time on evaluating the scans and have a right to see their results published.
Furthermore, without the help from the U.S.
and Germany the
scans would never have materialized in the first place. While pride in the
achievements of one’s country is thoroughly understandable it should not turn
into chauvinism because this has always led to disaster.
You have mentioned repeatedly that
you have enemies and that the forces of Seth are arraigned against you. This
may well be so but please feel assured that the scientific community is not
your enemy but is only interested in a search for the truth, regardless where
it ultimately may lead to. I would, therefore, like to urge you not to provide
those with whom you have differences with more food for animosity; which
secrecy surely breeds.
Those of us who love and respect
the magnificent culture your ancestors have given to the world would be
severely disappointed if this tradition of sharing, which has characterized
them in the ancient world were to be abandoned now. I, therefore, urgently
request that you reconsider your decision and follow the suggestions made above.
In American parlance this is a “win-win” situation where nobody loses and everybody
gains.
Sincerely yours,
Ernst Rodin MD
