Well preserved Antique Paper Manuscript from Mongolia
12 double sided pages plus the 3-disc device.
The manuscript is accompanied by
1) a circular diagram drawn one half on each of two folios, which together make a circle
2) set of 3 manipulative devices in the form of 3 circular discs of decreasing sizes that are to be place on top of the circle and fixed at the centre. These discs are free to rotate. The uppermost disc has a bow and arrow drawn upon it. This acts as a pointer in the calculations.
This is a valuable work from the point of view of the mathematics involved, the cultural aspect as well as the art. An absolutely fantastic acquisition!
There is some edge wear.
Size: 21 x 7 cm
Estimated to be from the late 1800s / early 1900s
Excellent for research.
Also included are some drawings on other subjects - may have been part of a larger thesis.
This item has spent a lifetime being used for the purpose of its creation with the original artist/user. Signs of this life lived heartily may be present on the piece in the form of stains, thread loss, loose threads, holes, tears, color run and other imperfections. Therefore the condition must be assumed to be “not” perfect. More photos of such imperfections will be provided on request.
