It is this number 573750000 and it is a Thom unit because it is base 17. That is what i forgot. So the Lunar cycle is the nodal cycle as 6800 days /17 = 400. Following the nodal cycle is important because eclipse danger periods can be tracked.

These fall every 173.333r days and the system Thom discovered tracks these periods via diameters.

5440 / 1632 x 520 = 1733.3333 so 10 danger periods 5440 is the Thom mile.>

Hi David,

The last time I looked at that figure you mentioned of 1733.333, it was in another topic I posted earlier last year found here:

Just a little more suspension on the tow line for now, :)>

Never thought I would see it again so soon in A.Thom's work, but nice to see anyhow. :) All of this ancient info has been passed down through the ages in very unusual ways it seems. I was working on units of the earliest coined money when I came across this figure for the first time as a ratio of gold to silver in the Persian empire of Darius the Great.

I don't know if that is further confirmation of the validity of A.Thom's work or not but I think it is anyhow. The Persians were great astronomers you may well know, as well as great mathematicians. What I find most intriguing about all of this, is these numbers of 1225 and 2080 are both magic square numbers pertaining to 7 and 8, which John Michell saw as crucial to ancient understanding of the Cosmos. Together with the magic square of 4, which generates the factor 17 x 8 = 1-16 = 136. I've been studying these patterns for a long time now thanks to JM's first publications, View Over Atlantis and City of Revelation, which I first read as a young man in my early 20's. These are not circumstantial coincidences when you find these patterns expressed in so many ways by these earliest civilizations. JM saw the pattern of the magic square of 8 expressed in the circular post hole pattern of Woodhenge. I can't confirm this pattern but it intrigued me a lot long ago. It's nice to see these patterns in definite and provable evidence of their use such as I have found recently. It's just one of the trail of clues I use instinctively now in my studies.

Happy New Year to you,

Stephen
