(This is a follow-up on my previous entry Niankhkhnum and Khnumhotep. This post also uses Code2000 font to display some unicode characters, available free for download.)
I found a very thorough post by Katherine Griffis on alt.history.ancient-egypt, written in May 2005 (read it here). She discusses in detail various issues about the tomb of Ni-Ankh-Khnum and Khnum-Hotep and even some mistranslations of the Egyptian words ḫnm and ḥtp made by others.
Obviously, I'm going have to start doing some digging into this archaeological conundrum, pardon the pun.
