Uncover the story of a copper-alloy sculpture from ancient Mesopotamia as it is CT-scanned by a team of researchers. In this collaborative research project between The Met and the Republic of Iraq, new findings are discovered about the ancient art-making technique of hollow-core lost-wax casting, an innovative breakthrough that is still used by artists today.
Recent provenance research by the Museum’s scholars established that the work rightfully belongs to the Republic of Iraq, prompting the Museum to reach out to His Excellency Nazar Al Khirullah, Ambassador of the Republic of Iraq to the United States of America, and offer to return the work. During discussions that followed, The Met and Iraq agreed to embark on collaborative research on the sculpture, including sending it for high-powered scanning at a specialized lab in Germany. This partnership demonstrates our shared commitment to advancing the understanding of human history and creativity. The work was returned to the Republic of Iraq in a ceremony at The Met on September 30, 2025.

This is an object that is so direct.
I mean, it's really looking at you.
You feel like it's something you can commune with.
I'm not saying this is a divine animal,
but if it is a ritual object,
it is navigating between the world of humans
and the world of the divine.
The stand with an ibex was formally accessioned in 1974,
and since 1977, it was pretty much always on display here at the Met.
We've enjoyed it tremendously and loved it many years.
This object, one of the earliest and important objects from Mesopotamia,
is an object of not only profound beauty,
but also in a very good preservational condition
and well worth presenting, preserving, but also researching.
The Met is deeply engaged in the preservation of objects,
but also in the deep understanding of objects,
where they come from, how they came into this collection.
While doing that significant provenance research,
we realized that this specific object legally belongs to the Republic of Iraq.
So we are returning and restituting this object.
This is a very unique object.
It's part of our policy, and the Iraqi Embassy here,
and with the support of our government,
through diplomacy, negotiation, and close partnership,
to return such kind of unique object back to the homeland of Iraq
and preserve Iraqi heritage.
It is a significant step on our partnership.
Our colleagues at the Iraqi Embassy thought it was a great idea
that we proceed with the research we had already wanted to do,
but do it together with our colleagues in Iraq.
And that makes it, you know, even better as a project.
We're here today to look at the vessel stand with IBEX support
with the proposed dating in the mid-third millennium B.C.
The IBEX stand belongs to a period
that is very early in the formation of Mesopotamia,
right after, you know, writing has been invented.
I mean, writing comes from this part of the world.
And so this is a time and a place that is incredibly formative
to not just the field of West Asian studies,
but I would argue world history.
We know from analysis that it was made from almost pure copper.
The eyes are both inlaid.
Actually, the one on the proper left is a reconstruction.
But on the proper right, the eye is inlaid with shell,
and the pupils are lapis lazuli,
which would have come from the area that is now Afghanistan.
And also the copper itself was sourced
in the mountainous regions surrounding Mesopotamia.
It's an early example of Sumerian ritual culture.
These four rings on top suggest that they were used
for sort of conical vessels, which are typical of libations
that would be performed in a temple.
And it is also a very, very early example,
possibly the earliest example
of the hollow-core loss-wax casting technique.
Here you see that the process begins
with the creation of a core out of clay
covered with wax in which you will create the designs
that you would like in the final casting.
After the wax has totally worked to your satisfaction,
you would add these other channels in wax
for the metal during the casting process.
You would use core supports, which were little pieces of metal
that you would drive through the wax into the core.
These would then hold that core in place
after the wax was melted out.
This is an example of the final product of this process,
and here you can see on the piece that these core supports
were taken out of this cast,
and they would have been plugged with small pieces of metal.
The hollow-core loss-wax technique.
Maybe even up until now, we've always situated
both from a time and from a locality
more into ancient Greece and Rome,
but to be able to continue the research that has been going on
about how this object came into existence
allows us to appreciate Mesopotamian culture
even more than we did before.
We have an extraordinary conservation
and scientific research lab,
but the metal is thick enough that it's hard to see
that level of detail in normal X-rays
and technologies we have here at the Met.
So we're really interested in doing a CT scan
of the body of the ibex.
I'm very excited that we have the opportunity
to bring this object to the Fraunhofer Institute in Germany.
They have a long history of working on the analysis
and examination of cultural objects.
Our conservator, J.F., will be met by an Iraqi conservator,
Roa Abbas Khadim, from the National Museum in Baghdad,
to see exactly how it was made, verify that it was hollow core,
to discuss together what this all means.
So nice.
We're very excited about this research,
because it's the first joint research
between the Metropolitan Museum and the Iraqi Museum.
And there's proof that the country between the two rivers
was the first to use this technology
before the Greek civilization, 480 BC.
It's kind of amazing to think it's 4,400 years old
and it's survived largely intact.
For art historical research, CT gives the big benefit
that it's non-destructive, so most of the time
you're not really sure in which condition the piece is.
And with X-ray, or specifically CT technology,
you're really able to look inside.
So that's an essential, more or less.
It's really exciting for us
to help gain some further knowledge.
We did a CT scan of the e-bags.
This is really good for, in this case,
copper parts, which are very, very thick, which are very dense.
Small details up to 200 microns are seen inside.
Good, so here we have the first view.
Oh, wow, you can see a lot of detail.
It was kind of impossible to see with a 2-dimensional radiograph.
It's amazing to be able to see the original shape of the core.
Very interesting.
I think this wire...
So you're happy?
I'm happy so far.
Everything's fine.
What about sort of like that frontality,
approaching him as I think it was meant to be?
You know, if it's a ritual object,
you know, the frontality is so key.
Hi, J.F., welcome back.
Hello, thank you.
How was it?
It went very well.
One thing I can say, it was really wonderful
working with Roha there and with Frauhofer
because they're essentially midway between us and Iraq
and also giving them a connection to the Iraq Museum.
Was there one surprising thing about the process?
Right, well, yeah, there are some kind of unusual aspects
to the back of the core,
and I'm not quite sure what is happening there.
It may have been that there was some fragmentation of the core
when they were inserting the core supports
prior to, you know, enveloping the whole wax in the mother mold.
It's like an alchemical process
where you take these raw materials
and through the magic of skill and chance and luck,
gradually the technique improved and spread.
Look, we're using it today.
Sure.
And it'll be the beginning of a whole new chapter,
a wonderful chapter.
Here at the Met, our primary job
is to care for the objects in our care.
But an object is not a museum.
Museums are objects, spaces, and people.
And it's also the relationships we build
in the process of caring for the objects under our stewardship.
It is an honor to work together with His Excellency,
the Iraqi ambassador to the U.S., Nasser al-Karoula,
and with our colleagues in Iraq
to return this important IBEX sculpture.
And we look forward to continuing our partnership,
our collaboration, and our fruitful exchanges
from here towards the future.
I would like to take this opportunity
to thank the Metropolitan Museum
on their scientific and ethical work.
The joint research presented advanced understanding
of a technique which has impacted cultures across the world.
So we are very proud.
It really is.
It's just a very special piece.
And it's been a privilege and an honor
to take care of it for many years.
