i know that you have all noticed the connection that myth had with the number 7.
now then, have you also noticedn the connection tolkiewn made with the number. in the return of the king, gandalf recites the verse "...seven stars and seven stones..."
also there are seven seeing stons, or palantirs, one in each of the 7 towers of the empire of gondor.
also,
seven for the dwarf-lord in their halls of stone,
a verse from the poem of the rings.
