A paperfolding paradise
The website of writer and paperfolding designer David Mitchell
|Deliciae physico mathematicae Volume 2 by Georg Phillip Harsdorffer, 1651|
2 of 'Deliciae physico mathematicae' was a follow up to
Daniel Schwenter's 1636 book written by Georg Phillip
Harsdorffer, and published in 1651. I cannot read German
and so could possibly have missed relevant passages which
are not accompanied by illustrations.
A full copy of the work is available at https://books.google.co.uk/books?id=BlU_AAAAcAAJ&pg=PP7#v=onepage&q&f=false
Pages 117 and 118 give cut and fold nets for the cube, octahedron and dodecahedron.
Page 57 shows a quartered circle which may be intended to be folded to act as a right angle template. The meaning of the text which accompanies the picture is not clear to me.
