Egyptian Blue Found on 2,700-Year-Old Taharqa Shrine

Visible red survives in carved crevices, while microscopic analysis, hyperspectral imaging, and infrared photography revealed yellow and Egyptian blue on the 2,700-year-old reliefs. The evidence matters because the stone scenes were conceived as painted images; a digital projection opening November 13 will visualize that color without repainting the monument.

 
 

Egyptian Blue Returns to the Shrine of Taharqa

The shrine is not an isolated statue but a sandstone room covered with carved royal and divine scenes. The Ashmolean dates it to 690–654 BCE and calls it the only free-standing pharaonic building in Britain. It originally stood inside the great temple of Amun-Re at Kawa, in present-day northern Sudan, where the Kushite king Taharqa ruled Egypt and Kush.

The walls show Taharqa making offerings to gods. Their present beige appearance can therefore be misleading: relief carving supplied form, while paint differentiated bodies, garments, crowns, offerings, and divine attributes. Color was part of the image’s operation, as it was throughout the broader tradition of Egyptian art, rather than a decorative finish added after the important work was complete.

According to the Ashmolean’s November 4 announcement, microscopic examination and specialist photography found surviving color traces. From November 13, projected blues, reds, yellows, and other colors will follow the carvings across the original walls. This is light placed on the surface, not new paint applied to ancient stone—a reversible interpretation rather than a physical restoration.

What the Pigment Evidence Actually Establishes

The public evidence supports a colorful shrine, but it does not support treating every projected hue as an equally direct scientific finding. The Art Newspaper reported on November 2 that red remains visible in carved crevices, while microscopic analysis and hyperspectral imaging disclosed yellow and Egyptian blue that are now difficult or impossible to see unaided.

The distinction between measured material and reconstructed appearance is clearest color by color:

Color	Measured basis	Public limit
Red	Fragments remain visible in relief crevices.	Local survival does not provide a complete red map.
Yellow	Microscopy and hyperspectral imaging detected traces.	No chemical identity or scene map has been released.
Egyptian blue	Infrared and luminescence imaging located surviving material.	A 2015 study identified two blue-skinned depictions of the Nubian god Amun-Re and two non-blue depictions of Theban Amun-Re.
Other projected colors	The museum announces additional hues.	The release does not enumerate their material evidence.

Egyptian blue is consequently the only pigment tradition named in the announcement; “red” and “yellow” remain color descriptions rather than disclosed mineral identifications. The museum says the blue appears to have been reserved for specific divine figures and imagery, wording that makes an art-historical claim about selective use without identifying each figure. The projection may draw on surviving traces, comparable monuments, and informed interpretation, but those categories should remain visible to viewers instead of collapsing into a single promise of “original color.”

 
 

The Discovery Began Decades Before the Projection

Scientific investigation of the shrine includes microscopy conducted in 1990, luminescence imaging in 2015, and broader spectral work begun in 2017. David Howell’s chapter in the 2018 scholarly volume Digital Imaging of Artefacts records that the shrine’s fragile painted surface was consolidated with cellulose nitrate soon after its arrival in Oxford. Cellulose nitrate was removed from three walls in 1968; the remaining west-wall coating was later found to be disrupting the paint layers. Microscopy followed in 1990 on samples taken before that removal.

A photo-induced-luminescence study was conducted in 2015 specifically to locate Egyptian blue. Further investigations began in late 2017 using photogrammetry, X-ray fluorescence, Raman spectroscopy, and hyperspectral imaging. Because the many-ton shrine could not pass beneath a scanner, the equipment was adapted to move past its vertical walls. That record establishes that the blue’s localization predates the current announcement by more than a decade; the 2026 development is the public synthesis of accumulated research into a mapped visitor experience.

The object’s physical journey has a less tidy public record. Francis Llewellyn Griffith began Oxford’s excavations at Kawa in 1929; the Sudanese government later ceded the building to the expedition, and Nora Griffith presented it to the Ashmolean in 1936. The current release says its blocks traveled in 150 crates. An older Ashmolean education sheet says 200, a number repeated by Smithsonian Magazine. The current release gives 150 crates for transport to Khartoum, while an older education sheet gives 200 for the shipment routed through Port Sudan to England, so the figures may describe different stages of the journey.

Color Joined Kushite Kingship to Divine Authority

The relief cycle presents Taharqa through more than one visual language. On the west wall, the museum’s educational record identifies him in a Kushite royal headdress with two cobras while offering to Amun-Re; elsewhere he wears the double crown associated with Upper and Lower Egypt. Other walls assemble deities connected with Memphis, Heliopolis, Thebes, and Kawa. The changing regalia and divine company make the shrine a statement about rule across interconnected territories, not simply a repeated sequence of offerings.

That context matters when interpreting the reported restriction of Egyptian blue to divine imagery. If color differentiated sacred status within the carved procession, the finding changes how the reliefs are read: figures that now share the same sandstone tone once occupied a hierarchy articulated through both carving and pigment. Photo-induced luminescence has already identified blue-skinned depictions of Nubian Amun-Re and non-blue depictions of the god’s Theban form.

The shrine belongs to the histories of both Egypt and Kush, and its origin in what is now Sudan keeps it central to the study of African art. Treating it only as an “Egyptian shrine” obscures the Kushite patron, the Nubian site, and the political reach expressed by Taharqa’s changing crowns.

What the Imaging and Records Now Establish

• Red, yellow, and Egyptian blue survive on the reliefs, but the museum has publicly named Egyptian blue alone as a specific pigment tradition.
• Microscopy began in 1990, Egyptian blue was located through luminescence imaging in 2015, and broader spectral investigation followed from late 2017.
• The November 13 installation is a digital projection informed by that research, not a repainting or material restoration of the sandstone.
• The museum’s public documents disagree between 150 and 200 transport crates, while exact pigment maps and the identities of the red and yellow materials remain undisclosed.
