Many here will be aware that the ‘Toys’ page in Johann Bessler’s Maschinen Tractate was numbered MT 138, 139, 140 and 141. I suggested that the drawings he destroyed or buried were replaced by this curious page of what appear to be toys, but perhaps there was another reason.
The previous page was numbered MT137, which was the logical number for the preceding page. As I pointed out previously MT137 contains the musical ‘circle of fifths’, plus if you use two radii to divide a circle according to the golden ratio it yields sectors of approximately 137° (1.618, the golden ratio) and 222°, hence the number 137.
So 360/1.618 = 222.5 . 360-222.5=137.5 Curiously 1/137.5 = 00727272727 etc. 5x72=360.
The pentagram is of course constructed with numerous examples of the golden ratio.
I should add there is a huge amount of discussion in scientific circles about the mystery of the number 137. https://en.m.wikipedia.org/wiki/137_(number)
The final number on the Toys page is 141, is an interesting choice. The number of Bible references in Bessler’s Declaration of Faith also number 141. Only 3 and 47 are divisors of 141. This brings to mind Euclid’s 47th problem. MT47 has a curious feature, the number 47 is repeated upside down within the drawing.
Bessler seems to be underlining the importance of the number 47. It could suggest the requirement for a 3:4:5 right angle in his wheel?
Other reasons occur to me which could explain Bessler’s inclusion of these numbers but it would be too much speculation at this point.
I’m aware of suggestions that Bessler was involved with FreeMasonry and so I offer the following information gleaned from
“The 47 Problem of Euclid or 47 Proposition of Euclid is also known as the Pythagorean Theorem. It is represented by three squares.
