Jean Yves Empereur is the Director of Research at the
CNRS (French National Research Center), and the Director
of the French Center for Alexandrian Studies in
Alexandria, Egypt. He recently spoke with NOVA about his
ongoing work in the harbor of Alexandria.
NOVA: Apparently it has been known since the time of
Napoleon Bonaparte that there were interesting artifacts
underwater in the harbor of Alexandria. Can you tell us why
the area was not investigated fully until '94?
Empereur: There are several reasons. The first one is
that the regulator was invented by Cousteau in 1943. And so
before it was difficult to proceed with underwater
excavations. And it's only in the early '50s that Cousteau
himself began to do underwater archaeological excavations. In
Alexandria during the Second World War it was a little bit
difficult to dive, because there was a continuous state of
war. The area was continuously occupied by the Egyptian
Marines. And you have to get a lot of permits to be able to
dive, and it's somewhat difficult to get these permits. The
Northern coast of Egypt is difficult for diving.
NOVA: I understand that much of the ancient city of
Alexandria has been lost through centuries of building. Were
the objects in the harbor protected from that development and
does that make this site particularly important?
Empereur: What is interesting underwater is that there
is no construction. When we make rescue excavations in the
city on land, once a year an old building, a cinema, a theater
or a storehouse comes down, to build a new tower of offices.
What we see is occupied from just now until
ten meters (33 feet) down
with all the states of occupation of the city. So Mamluk,
Byzantine, Roman, Greek and so on. In the water it's
completely different. It's protected from antiquity until now.
There was no more recent occupation. And so we find exactly
the state from antiquity—without new
occupation—and that's really interesting.

NOVA: You believe that you have found the Pharos
lighthouse. Is it possible that some of these blocks might
belong to some other type of monument, such as a temple?
Empereur: Of course. They're from more than 2,500
architectural pieces. And we believe that most of
them—about 99 percent of them—belong to other
monuments of the city. For instance there are some sphinxes,
some obelisks, some columns, which belong to other monuments
of the city.
But what we think belongs to the lighthouse itself—it's
only a very few, a dozen of the architectural pieces, which
are more than 70 tons. But we believe that these few elements
were very difficult to move them the place where they
collapsed from the lighthouse itself.
NOVA: How did the lighthouse wind up under water?
Empereur: From the fourth century until the 14th
century there were earthquakes in Alexandria. In the Arab
sources alone you have more than 20 mentions of earthquakes
which affected the lighthouse. And we know that in the 14th
century, after the Arabs had made some repairs to the
lighthouse, the lighthouse collapsed due to very severe
earthquakes. There is a map in Montpelier, a town in southern
France, which indicates that in 1303 the lighthouse of
Alexandria was destroyed. In fact, there is an Arab traveler,
his name is Ibn Battuta, who came to Alexandria in 1326 for
the first time. And he writes, "I could have access to the
door of the first floor of the lighthouse." And when he comes
back to Alexandria in 1349, he says, "No access to this door.
Everything here has collapsed." So in fact, in the first half
of the 14th century that very strong earthquake put an end to
this tower. This earthquake made the lighthouse collapse in a
kind of line from the seashore. And we found a dozen fallen
pieces under the sea in a line. Some of these pieces were in
fact broken in two or three fragments, each of which is about
20 or 30 tons.
NOVA: Did you use your map to help you figure out which
piece came from the lighthouse?

Empereur: Yes, of course. This was made clear by the
computer. First we made a map, a very accurate map with GPS,
with electronic theodolites, and so on. After we completed
this map we understood what happened—what could be drawn
and understood on this map with lines, with concentrations of
architectural pieces of the same kind and so on. [Read
"Mapping the Treasures"
to find out more about how this experimental map was made and
used.]
NOVA: Have you found any Greek lettering on any of the
blocks, or just Egyptian hieroglyphs?
Empereur: We have found only one marble piece which
bears alpha, rho, tau, sigma and omega—five letters in
Greek. In fact, it was a very huge inscription, because the
letters are more than 30 centimeters high and were in bronze.
We found only the traces of these letters with holes in the
marble. With five letters it's difficult to complete the
inscription and to have an idea of the general text. But there
is an American scholar who wrote an article about this
inscription. And he made a restoration of the wall text,
saying that, in fact, we discovered the inscription of the
lighthouse itself.
NOVA: Are most of these blocks dated to the same time,
or do you not know that?
Empereur: Yes, we know that they belong to the Greek
time. For instance, the colossal statues which stood at the
foot of the lighthouse itself, we are certain that they are
portraits of King Ptolemy. And what's interesting is that
these Greek kings chose to be represented as pharaohs. That
means that they were not only the masters of the Greek city of
Alexandria, but of the whole country named Egypt. Every
captain, every traveler entering the harbor of Alexandria was
obliged to pass in front of the statue of the kings and
queens—the kings as pharaohs, and the queens as the
Goddess Isis. It was a kind of royal propaganda.
NOVA: We've heard that 26 sphinxes have been found in
the harbor. What are all those sphinxes doing there? Were they
part of a monument or were they thrown out?

Empereur: What are they doing? They are playing with
fishes [laughs]. In fact, they're very different one from the
other. They belong to different pharaohs. The more ancient
belongs to Sisyphus (Sesostris) the Third who belongs to the
12th dynasty. And it's very different from another one
belonging to Pharaoh Psamtik the Third, who belongs to the
26th dynasty, which is in the 6th century B.C. So there is a
difference of 1,300 years between them.
And all the 26 sphinxes we have found up to now are very
different, belonging to different pharaohs, different by size,
different by even the material—some come from granite,
some from quartzite and so on. And so they do not belong to a
row of sphinxes like in Luxor or in Karnak. In fact, they all
come from Heliopolis, which is north of Cairo and was
destroyed at the time of the Greek Ptolemies. This very old
pharaonic sanctuary was used as a quarry. They took from it
obelisks, sphinxes, and all kinds of pharaonic pieces to use
in Alexandria. Some of them were used as decoration for the
city as obelisks or sphinxes. Others were used as building
materials. Some of these obelisks or sphinxes were used in
Rome or in London or even in New York. The obelisks of Central
Park near the Metropolitan Museum, in fact, come from
Alexandria.
NOVA: Now that you have removed a lot of artifacts from
the harbor, do many still remain? And can people go to
Alexandria and dive to see them?
Empereur: Yes, there is a plan by the Egyptian
authorities to transform this archaeological site into an
archaeological park. And to let people dive and have a look at
these antiquities underwater. First they'll have to fix the
sewage problem. Then we have to complete, of course, the
excavation, which should be in the fall of '98. The third
point is that they have to transform this Qaitbay Fort into a
lighthouse base and a lighthouse museum, to let people rent
suits and so on for diving. So I think that you have to wait a
little bit more, for say two, three, four years to get this
park ready for amateur divers, so they can have an idea of
this very impressive site.
NOVA: Do the blocks need to be protected in any special
way once they come out of the water?

Empereur: Yes, of course. There is a special treatment.
This treatment is needed because there is a lot of salt inside
the epiderm [skin] of these blocks. And you have to remove it.
And so the same day that you remove the blocks from the bottom
of the sea, you have to put them in water tanks with the same
percentage of sodium that there is salt in the seawater. Then
you reduce smoothly this percentage of sodium until the blocks
have released all the salt they have inside. Once they don't
release any salt into freshwater, it means that the process is
finished. And this process took six months. And now they are
exposed to the open air without any problem because there is
no more salt inside these architectural pieces or statues.
NOVA: We've heard that there are Greek and Roman
shipwrecks not far from where the lighthouse was found. Can
you tell us more about that?
Empereur: Yes. This is a new discovery we made last
November. We knew from ancient sources that the entrance of
the harbor of Alexandria was very dangerous. This is due to
the rocks which are at the surface of the water, or just below
the surface. In fact, we discovered from 300 meters from the
coast to 2 kilometers from the coast some Greek and Roman
shipwrecks, from the 4th century B.C. until the 7th century
A.D. This is a very new and rich documentation on the trade of
Alexandria with the rest of the Mediterranean.
NOVA: What are your plans for working there?
Empereur: We are doing a survey now to make a new map
on this zone. And now we have a map which is in progress, with
anchors, with these shipwrecks, and so on. For several months
we have been excavating one of these shipwrecks. This
shipwreck is the cargo of an Italian ship from the 1st century
B.C., around 50 B.C.—the time of Caesar. These
shipwrecks are full of wine amphoras imported from Greece,
from northern Turkey or from Italy, Spain, North Africa. And
even some plain pottery and fine pottery lamps, and you can
even find the anchors of the ships.
NOVA: How many shipwrecks do you hope to find?
Empereur: We don't know exactly, because this work is
in progress now. But so far we have more than one dozen such
shipwrecks, and I think perhaps that there are many, many
more.
NOVA: It sounds like your plate is full.
Empereur: Of course, but you are running from one place
to another, and it's a pity that there are no more
archaeologists working in this field, to collaborate, to save
more of the antiquities of this capital of Ptolemies.
NOVA: Well, thank you very much for your time and good
luck with the shipwrecks and everything else you are working
on.
Empereur: Thank you very much. See you in Alexandria
one day I hope.
