This statue represents Tutankhamun as Amun and it was discovered in the Karnak temple Cachette in 1904.  The statue is 155cm high and is carved from Limestone.

In this statue he is wearing the twin plumes of Amun. His hands hold the Isis knot and he is standing with his left foot advanced. 

Tutankhamun, in the popular theory, restored the cult of Amun after the death of Akhenaten (Amenhotep IV), and he changed his name from Tutankhaten (living image of Aten) to Tutankhamun (living image of Amun). This was very probably politically expedient, and even necessary for his continued reign.  Theories about his parentage, life and death are abound.
