|The Love Knot Letterfold|
page attempts to record what is known about the origin
and history of the origami design known as the Love Knot
Letterfold. Please contact me if you know any of this
information is incorrect or if you have any other
information that should be added. Thank you.
In the manuscript De Viribus Quantitates by Luca Pacioli, dated to around 1502, and possibly produced in collaboration with Leonardo da Vinci, contains a section headed 'To seal a letter without any wax' which includes the following wording:
'Given a rectangular sheet of paper, one is to fold it widthwise so to obtain a strip of paper. Both ends of the paper are bent in such a way to obtain a similar trapeze standing out to each side of the strip. The side of the trapeze gives the next fold, which is to be folded over until both ends are close enough that after folding them into each other they form a square shape.'
This sounds very like the Love Knot Letterfold.
The first illustration of this paperfold appears in Eleonore Heerwart's 'Course in Paperfolding', which was first published in Dutch in 1895 then in English by Charles and Dible in London and Glasgow in 1896.
The design also appears in 'Pleasant Work for Busy Fingers' by Maggie Browne,which was published by Cassell and Company in London in 1896.
