I still don't understand how 1618 fits in here, but I believe you. I wish I could show you my geometrical drawings in relation to the pentagon, where for sure 1618 plays a big part. I have constructed a big birdbath and other items in the shape of pentagons and had to make the drawings first.
Baktun. I just looked it up and now I have an idea of it. The Indians (over in India!) also have a similar thing, to do with 144 000.
It is a pity that everything gets muddled up by those who have not studied these things, just like the paranormal. Because of that muddling it gets to be ridiculed. But hopefully there will come a time of real wisdom!
I will write you a pm, so look out.
