Wesir (Osiris) is one of the most important of the Netjeru (gods), and King of the Duat (underworld). The Wesir mythology is some of the most complex of the Egyptian beliefs. His various attributes and stories accrued over time as his cult gained in popularity and universality. His name means "the place of the eye" and from early times was a chthonic diety, also symbolizing fertility. He is usually portrayed mummiform, his hands free of wrappings and holding the crook and flail and wearing the atef crown. His flesh is shown as white, symbolizing the linen mummy wrappings, or green for resurrection (the sprouting of the grain in the spring), or black to symbolize the Black Land, the alluvial richness associated with fertility.

Wesir's fertility goes back to his beginning's, probably even representing the growth of the crops - a corn god. First the corn was trod into the dark earth (burial) and then sprouted analogous to resurrection. It seems that he assorbed the attributes of other Netjeru (gods) as time went on.

His best known epitaph was Wennefer translating as "eternally good" or "the perfect one" implying his incorruptibility (in death). He was also known as the "chief of the westerners" - in Egyptian Khentamentu - or "he who dwells in Heliopolis" designating him as part of the Ennead.
