Egyptian curses may be esoteric, but they certainly formed a large and real part of the Egyptian funerary process. The tomb of the Elders of Meni at Giza, cut out in the 6th Dynasty is inscribed with a particularly famous curse. It reads:
"May the crocodile be against him in the water, and may the snake be against him on land, any man who would do harm against this [place]. Never have I trespassed against him - It is God who will judge him."
Personally, I like a lot discussing about carvings of curses over the tombs' doors. They are anthropologically interesting and can also give an idea of differences on languages, changing details of the religion throughout centuries...but please, leave curses like that of King Tut!...they are really ridicolous! Or would you consider to make offerings to the gods Sobek and Wadjet, or Uto, in case you'll have the chance to visit the tomb of Meni?
To tell the truth, when I entered tombs and temples, I felt the need to greet the owner or the gods to whom the temple was dedicated...but this is just my feeling...this is not science!
