The discovery of King Tutankhamun's tomb in 1922 attracted the world's attention. The tomb of the ancient pharaoh is the only known find in its original state. The thieves did not loot the tomb (Sayre, 2011). According to Rompalske (2000), the tomb of King Tutankhamun was found in the Egyptian Valley of the Kings. The nearby burial sites have long been looted by grave robbers or damaged by floodwaters. Somehow, the tomb remained undisturbed for 3,000 years. This undisturbed condition is significant because the world knew what contents should be in a pharaoh's tomb only from ancient writings. The world has never seen the actual contents of a pharaoh's tomb intact. Furthermore, at the very moment of the discovery of the tomb and before breaking through the sealed door, an elderly British romantic writer Marie Corelli, specializing in supernatural phenomena, wrote about an ominous warning, a "mummy curse", according to which anyone who intrudes into a sealed tomb will suffer or die (Marchant, 2013). The recipient of Corelli's warning is the famous British archaeologist Howard Carter and his financier George Herbert, a very wealthy fifth Earl of Carnarvon. It is the intention of this report to identify the mystery surrounding the curse and dispel or validate its accuracy. Mystery of the curse. The mystery of the curse began about a month after Howard Carter and Lord Carnarvon breached the inner door of the tomb. Lord Carnarvon contracted a mosquito bite on his cheek and fell ill and subsequently died. Immediately people thought that his death was the result of the mummy's curse. According to Marchant (2013), the curse of the mummy was already a popular story, but the death of Lord Carnarvon and Corelli's chance prediction turned it into a worldwide frenzy. Furthermore, according to Handwerk (2005), it is possible that Carnarvon's death was due to exposure to ancient toxic pathogens. Egyptian tombs contain not only mummified bodies but also food products intended for use by the dead in the afterlife. Jennifer Wagner, an Egyptologist at the University of Pennsylvania Museum in Philadelphia, believes these foods attract not only insects, but also mold and bacteria that can be toxic and deadly. Analysis of the mystery. Ancient mummies definitely carry mold based on laboratory studies (Handwerk, 2005). There are at least two deadly types of mold; Aspergillus niger and Aspergillus flavus.
