There is one rather unglamorous
theory about the origin
of the ankh symbol
: it is quite possible that it has evolved from the hieroglyph
'. The loop is the sole
and the three line extruding
from it are the leather thongs
used to tie the sandal to the foot.
Needless to say, this theory tends to irritate goths and anyone who sees it as a symbol for life, balance or the union of man and woman. It does seem to carry some academic merit though.
