Reposted from another thread:

The reverse paradice at the end of the 340 might suggest that there is indeed a word game embedded in the cyphertext, and that there is another layer to crack, or at least to figure out. There are some reversed, non-reversed, and some slightly scrambled words in the cyphertext.

Then there are all those symmetries which are noted in a different thread (viewtopic.php?f=81&t=4342), which become much more interesting now that we know that the cypher is broken into two blocks of nine lines. The ninth line is bracketed by the two dash symbols (-) and the middle of that line, counting from the dashes, is a cross.

Then, of course, there is the zodiac signature right in the cypher text at the end of the message.
