- To make one's mark is the way a leagal document
was verified and usually accompanied by a witness to
this marking. People along time ago used various types
of ways to mark there documents from a fingerprint
to a drop of wax and a seal on a ring to press into
the still wet wax. The "X" was more of a common form
of marking followed by a witness who saw this person
mark on the paper. <br>Grammar did not come about
until around 400 B.C. Before that pictures were used.
Around the 16th century the pencil was developed. Sorry
got ahead of myself anyways concidering the other off
the wall info. I hope this helps also and that site
that Marie gave gives some information.
