the Greek psestos, which designates a text inscribed
on a surface through incising or scratching, which is sometimes
synonmous with the word 'graffiti (provided said graffiti are
made on parchment), palimpsest
was also named
pergamentus rescriptus or even codex rescriptus by
the Medieval-- scholars. Codex rescriptus, of course,
referred to a book that was written on top of another book.
In the case of these scholars, the reason
for such a procedure was not at all a 'spirit of deconstruction' in the
modern sense of the term.
