The mask of Tutankhamun is a gold funerary mask that belonged to Tutankhamun, who reigned over the New Kingdom of Egypt from 1332 BC to 1323 BC, during the Eighteenth Dynasty. After being buried with Tutankhamun’s mummy for over 3,000 years, it was found amidst the discovery of Tutankhamun’s tomb by the British archaeologist Howard Carter at the Valley of the Kings in 1925. Since then, it has been on display at the Egyptian Museum in the city of Cairo. In addition to being one of the best-known works of art in the world, it is a prominent symbol of ancient Egypt.

Bearing the likeness of Osiris, the Egyptian god of the afterlife, the mask is 54 centimetres (21.3 in) tall, weighs over 10 kilograms (22 lb) or 321.5 troy ounces, and is decorated with semi-precious stones. A spell from the Book of the ᴅᴇᴀᴅ is inscribed in Egyptian hieroglyphs on its shoulders. In 2015, it had to be restored after its 2.5-kilogram (5.5 lb) plaited beard fell off and was hastily glued back on by museum workers.

According to the British Egyptologist and archaeologist 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.”Since 2001, some Egyptologists have suggested that it may originally have been intended for Neferneferuaten, a female pharaoh who reigned near the end of the Amarna Period.

Tutankhamun’s burial chamber was found at the Theban Necropolis in the Valley of the Kings in 1922 and opened in 1923. It would be another two years before the excavation team, led by the English archaeologist Howard Carter, was able to open the heavy sarcophagus containing Tutankhamun’s mummy. On 28 October 1925, they opened the innermost of three coffins to reveal the gold mask, seen for the first time in approximately 3,250 years. Carter wrote in his diary:

The pins removed, the lid was raised. The penultimate scene was disclosed – a very neatly wrapped mummy of the young king, with golden mask of sad but tranquil expression, symbolizing Osiris … the mask bears that god’s attributes, but the likeness is that of Tut.Ankh.Amen – placid and beautiful, with the same features as we find upon his statues and coffins. The mask has fallen slightly back, thus its gaze is straight up to the heavens.

In December 1925 the mask was removed from the tomb and transported 635 kilometres (395 mi) to the Egyptian Museum in Cairo, where it remains on public display.

The mask is 54 cm (21 in) tall, 39.3 cm (15.5 in) wide and 49 cm (19 in) deep. It is fashioned from two layers of high-karat gold, varying from 1.5–3 mm (0.059–0.118 in) in thickness, and weighing 10.23 kg (22.6 lb). X-ray crystallography conducted in 2007 revealed that the mask is primarily made of copper-alloyed 23 karat gold to facilitate the cold working used to shape the mask. The surface of the mask is covered in a very thin layer (approximately 30 nanometres) of two different alloys of gold: a lighter 18.4 karat shade for the face and neck, and 22.5 karat gold for the rest of the mask.

The face represents the pharaoh’s standard image, and the same image was found by excavators elsewhere in the tomb, in particular in the guardian statues.He wears a nemes headcloth, topped by the royal insignia of a cobra (Wadjet) and vulture (Nekhbet), symbolising Tutankhamun’s rule of both Lower Egypt and Upper Egypt respectively. The ears are pierced to hold earrings, a feature that appears to have been reserved for queens and children in almost all surviving ancient Egyptian works of art. However, the Egyptologist Zahi Hawᴀss, a former Egyptian Minister of Antiquities, told Al-Monitor that the “theory about the ear piercing is unfounded because all the 18th Dynasty’s rulers wore earrings during their period of rule.”

The mask is inlaid with coloured glᴀss and gemstones, including lapis lazuli (the eye surrounds and eyebrows), quartz (the eyes), obsidian (the pupils), carnelian, amazonite, turquoise, and faience.

When it was discovered in 1925, the 2.5 kg (5.5 lb) narrow gold beard, inlaid with blue glᴀss, giving it a plaited effect, had become separated from the mask, but it was reattached to the chin using a wooden dowel in 1944.

In August 2014, the beard accidentally become dethatched from the mask when it was taken out of its display case for cleaning. The museum workers responsible used quick-drying epoxy in an attempt to fix it, leaving the beard off-center. The damage was noticed in January 2015 and has been repaired by a German-Egyptian team who reattached it using beeswax, a natural material used by the ancient Egyptians.

In January 2016, it was announced that eight employees of the Egyptian Museum were fined and faced discipline for allegedly ignoring scientific and professional methods of restoration and causing permanent damage to the mask. A former director of the museum and a former director of restoration were among those facing discipline.

A protective spell is inscribed with Egyptian hieroglyphs on the back and shoulders in ten vertical and two horizontal lines. The spell first appeared on masks in the Middle Kingdom, 500 years before Tutankhamun, and was used in Chapter 151 of the Book of the ᴅᴇᴀᴅ.

Thy right eye is the night bark (of the sun-god), thy left eye is the day-bark, thy eyebrows are (those of) the Ennead of the Gods, thy forehead is (that of) Anubis, the nape of thy neck is (that of) Horus, thy locks of hair are (those of) Ptah-Sokar. (Thou art) in front of the Osiris (Tutankhamun). He sees thanks to thee, thou guidest him to the goodly ways, thou smitest for him the confederates of Seth so that he may overthrow thine enemies before the Ennead of the Gods in the great Castle of the Prince, which is in Heliopolis … the Osiris, the King of Upper Egypt Nebkheperure [Tutankhamun’s throne-name], deceased, given life by Re.

Osiris was the Egyptian god of the afterlife. Ancient Egyptians believed that kings preserved in the likeness of Osiris would rule the Kingdom of the ᴅᴇᴀᴅ. It never totally replaced the older cult of the sun, in which ᴅᴇᴀᴅ kings were thought to be reanimated as the sun-god Re, whose body was made of gold and lapis lazuli. This confluence of old and new beliefs resulted in a mixture of emblems inside Tutankhamun’s sarcophagus and tomb.
