Tutankhamun’s mask, or funerary mask of Tutankhamun, is the death mask of the 18th-dynasty ancient Egyptian Pharaoh Tutankhamun. It was discovered by Howard Carter in 1925 in tomb KV62 and is now housed in the Egyptian Museum in Cairo. The mask is one of the best-known works of art in the world. Bearing the likeness of Osiris, Egyptian god of the afterlife, it is 54 centimetres (1.8 ft) tall, weighs over 10 kilograms (22 lb) or 321.5 Troy Ounces, and is decorated with semi-precious stones. An ancient spell from the Book of the Dead is inscribed in hieroglyphs on the mask’s shoulders. The mask had to be restored in 2015 after its 2.5-kilogram (5.5 lb) plaited beard fell off and was hastily glued back on by museum workers. According to Egyptologist Nicholas Reeves, the mask is not only the quintessential image from Tutankhamun’s tomb, it is perhaps the best-known object from Ancient Egypt itself.

Tutankhamun was only the age of nine when he became king of Egypt during the 18th dynasty of the New Kingdom (c. 1332–1323 B.C.E.). His story would have been lost to history if it were not for the discovery of his tomb in 1922 by the archaeologist Howard Carter in the Valley of the Kings. His nearly intact tomb held a wealth of objects that give us unique insights into this period of ancient Egyptian history.

Tutankhamun ruled after the Amarna age, when the pharaoh Akhenaten, Tutankhamun’s probable father, turned the religious attention of the kingdom to the worship of the god Aten, the sun disc. Akhenaten moved his capital city to the site of Akhetaten (also known as Amarna), in Middle Egypt—far from the previous pharaoh’s capital. After Akhenaten’s death and the rule of a short-lived pharaoh, Smenkhkare, Tutankhamen shifted the focus of the country’s worship back to the god Amun and returned the religious center back to Thebes.

Tutankhamun married his half-sister, Ankhesenamun, but they did not produce an heir. This left the line of succession unclear. Tutankhamun died at the young age of eighteen, leading many scholars to speculate on the manner of his death—chariot accident, murder by blow to the head, and even a hippopotamus attack! The answer is still unclear. Tutankhamun’s much-older advisor (and possible step-grandfather), Ay, married the widowed Ankhesenamun and became pharaoh.

During the early twentieth century, Howard Carter, a British Egyptologist, excavated for many years in the Valley of the Kings—a royal burial ground located on the west bank of the ancient city of Thebes. He was running out of money to support his archaeological digs when he asked for funding for one more season from his financial backer, the fifth Earl of Carnarvon. Lord Carnarvon granted him one more year—and what a year it was!

At the beginning of November 1922, Carter came upon the first of twelve steps of the entrance that led to the tomb of Tutankhamun. He quickly recovered the steps and sent a telegram to Carnarvon in England so they could open the tomb together. Carnarvon departed for Egypt immediately and on November 26, 1922, they made a hole in the entrance of the antechamber in order to look in. The task of cataloging the finds was an immense undertaking for the team. Carter spent a decade systematically recording the finds and having them photographed.

Tutankhamun’s sarcophagus (a box-like stone container) held not one but three coffins in which to hold the body of the king. The outer two coffins were crafted in wood and covered in gold along with many semiprecious stones, such as lapis lazuli and turquoise. The inner coffin, however, was made of solid gold. When Howard Carter first came upon this coffin, it was not the shiny golden image we see in the Egyptian Museum today.

The image of the pharaoh is that of a god. The gods were thought to have skin of gold, bones of silver, and hair of lapis lazuli—so the king is shown here in his divine form in the afterlife. He holds the crook and flail, symbols of the king’s right to rule. The goddesses Nekhbet (vulture) and Wadjet (cobra), inlaid with semiprecious stones, stretch their wings across his torso. Beneath these goddesses are two more—Isis and Nephthys—etched into the gold lid.
