Timeline of Paperfolding History
This timeline is a work in progress. It is reasonably comprehensive for significant events relating to the history of recreational paperfolding between 1440 and 1928. Further significant events in paperfolding history will be added in due course. Suggestions for such significant events, especially early events, that ought to be recorded here are welcomed.

Where I record the earliest mention or illustration of a paperfolding design in the historical record this is to the best of my current knowledge and belief. This information may well change with further research as earlier instances come to light. If you already know of an early instance then please contact me with details of the evidence and I will update the timeline accordingly.

Introductory Notes

By paper in this timeline I mean any flat thin sheet made from cellulose fibres which are held together by chemical bonds. Card or cardboard is simply thick paper.

By folding I mean any change of direction induced by any means in the flat plane of the paper. By this definition rolling is a form of folding.

Paper is not, of course, the oldest foldable material. Foodstuffs such as dough, leaves and plant stems, animal skins and leather, cloth and felt, and metals were all folded long before we have any record of the folding of paper. Paper, however, folds in a very different way to these other materials.

While paper will both roll and take a soft fold, like cloth or leather, it will also take a hard fold, the line of which is retained when the fold is opened out. When a soft fold in paper is completely flattened some of the fibres and/or some of the bonds between the fibres along the resulting folded edge are damaged or broken allowing a hard fold to form. If the paper is opened out this line of damage can be seen as a crease. This crease forms a line of weakness which will act as a hinge allowing the paper to be refolded, then opened out again, along the same line of weakness. This folding and opening out can be repeated many times without obvious additional damage occurring and consequently without the paper separating into two parts, as metal, or leaves, for instance would be likely to.

We do not know when, where, or by whom paper was first invented, or whether it was invented accidentally or as the result of a deliberate experimental process. Nor do we know whether, if it was the result of a deliberate experimental process, it was intended to be a medium for writing or painting on, wrapping with, or something else entirely. We do not even know whether paper was invented just once in one place or several times independently in several places. What we do know, however, is that the earliest evidence for the existence and use of paper comes from China, and that we can trace the spread of the knowledge of how to make and use it from there to the rest of the civilised world.

Both paper itself and objects made of paper are ephemeral and the record we have of them at an early date relies largely on their chance survival or their mention or appearance in much less ephemeral sources such as books, fabrics, drawings and paintings. Like paper itself, it is likely that many of the paperfolding ideas and designs featured in this timeline are much older than the earliest evidence for their existence. Unfortunately, of course, we cannot know, even approximately, how much older they might actually be.

Writing the history of paperfolding is complicated by the fact that most historians of paper seem to concentrate almost exclusively on its manufacture and its use as a medium for writing, drawing or printing upon and largely ignore its history as a foldable material.

While this timeline is about the folding of paper I have also included some events relating to the folding of other materials where these are particularly relevant to the development of the story.

The four main reasons why paper has been, and still is, folded are:

1. To wrap other objects in order to protect them.

2. To keep powders, seeds and other small items both separate and together.

3. To reduce the size of a large sheet to make it easier to carry, store or bind together (and subsequently, of course, to thus allow a small folded sheet or object to be opened out to a larger size).

4. To conceal all, or part, of what is written, drawn, painted or printed upon it.

In recent centuries paperfolding has also come to be used for more widespread mathematical, scientific, educational and recreational and artistic purposes. In selecting the events to include on this timeline I have unashamedly concentrated on these more modern uses, without, I hope, forgetting that most folding of paper was originally done, and indeed still is done, for these four much more mundane purposes.

Sources of information are given on the more specific subject pages to which this timeline links.

The Timeline

8BC - China: Date of the earliest known fragment of paper, approximately 10 centimeters square and made from linen fibres, which was discovered during the restoration of an ancient garrison near the Yumen Pass at Dunhuang in northwest China. It has been written upon and is likely to have been part of a letter.

312-13- Iran: Most likely date of a group of five almost complete letters written in the Sogdian language, each of which had been folded several times, which were found in a ruined watchtower in Iran on the ancient Chinese frontier wall.

988 - Japan: The earliest known reference to a Kawahori, a pleated folding fan made of paper, appears in “Relationship with Japan of the Song History” which lists gifts given from Japan to the Song Dynasty in China.

1008 - Japan: Written around this date, the Tale of Genji makes frequent references to letters being folded or unfolded, for instance 'The Gosechi dancer, perhaps a little precocious, was delighted with the letter, which was on delicate blue paper very tastefully folded with papers of several colors.'

1100 - Japan: The oldest surviving kawahori, a pleated folding fan made of paper, the remains of which were found in the village of Akitsu in Japan, was made around this date.

1440 -The Netherlands: Illustration of the surprisingly sophisticated cut-and-fold Catherine of Cleves box appears at the bottom of a page devoted to St Agatha, in the magnificent Flemish illustrated manuscript known as the Hours of Catherine of Cleves.

1490 - Venice: Publication of an edition of the book 'Tractatus de Spaera Mundi' written by John Holywood, an English mathematician and astronomer, who is also known as Johannes de Sacrobosco, which contains a picture illustrating a solar eclipse. The picture shows two paper boats floating in a stylised sea.

1502 - Italy: Approximate date of the manuscript De Viribus Quantitates by Luca Pacioli, possibly produced in collaboration with Leonardo da Vinci, which gives the first known descriptions of the Chinese Wallet, the Cherries Puzzle, three methods of sealing a letter without wax, one of which seems to be the Chickenwire Letterfold and another a precursor of the Love Knot Paperfold, explains how to cook in a frying pan made of folded paper and also gives a method of constructing an accurate right angle, without using compasses, by folding a sheet of paper twice.

1520 - Italy: Around this date a child playing with a Chinese Wallet is shown in a painting by the Italian painter Bernadino Luini.

1537 to 1603 - Japan: The oldest known representation of the Orizuru ( or paper crane) on a kosuka, a decorative panel intended to be attached to the hilt or sheath of a sword, can be reliably dated to this period.

1584 - England: Description of the magic trick now normally known as the Buddha Papers in Book 13, chapter xxvi of 'The discoverie of witchcraft' by Reginald Scot, Esquire.

1606 - England: In his tragedy 'Macbeth' Shakespeare wrote of Lady Macbeth 'Since his majesty went into the field, I have seen her rise from her bed, throw her night-gown upon her, unlock her closet, take forth paper, fold it, write upon’t, read it, afterwards seal it, and again return to bed; yet all this while in a most fast sleep.' This is the only mention of paperfolding in Skakespeare. It was common practice at that time to fold a sheet of paper in half before beginning to write a document or a letter.

1614 - England: First performance of John Webster's play The Duchess of Malfi, the ms for which contains the words 'Our bodies are weaker than those Paper-prisons boys use to keep flies in ...' which is likely, but not certainly, a reference to the Waterbomb design.

1629 - Italy: Publication of 'Trattato delle piegature' by Mattia Giegher, the earliest known work on the folding of complex table decorations from starched paper napkins.

1636 - Germany: Publication of 'Deliciae physico-mathematicae, oder mathematische und philosophische Erquickstunden' by Daniel Schwenter, which contains the earliest known publication of the challenge of finding a way of standing a strip of paper on edge (which is solved by folding it in half).

1676 - England: The earliest known description of Troublewit is published in the book 'Sports and Pastimes: or, Sport for the City, and Pastime for the Country; With a touch of Hocus Pocus, or Leger-demain: Fitted for the delight and recreation of Youth' by John Clark, at the Bible and Harp in West-Smithfield, London.

1680 - Japan: Short poem by Iharu Saikaku 'Rosei-ga yume-no cho-wa orisue' in the 'Ittyuya Dokugin Onsenku" (4000 Haikus Recited Alone All Day and Night) which can be translated as 'The butterflies in a beggar's dream would be folded paper.' This is often taken as a reference to the Ocho and Mecho - female and male butterflies - made from folded paper - which are used to decorate sake kettles or containers during traditional Japanese wedding ceremonies.

1682 - Japan: Iharu Saikaku's novel 'Koshoku Ichidai Otoko' ('The Life of an Amorous Man') refers to the hero, Yonosuke, making 'a pair of birds with folded paper' (identified as Hiyoku-no Tori - a pair of birds, one male and one female) and 'a pair of paper flowers attached to stems'. The specific designs referred to cannot be identified.

1692 - Japan: Publication of the 'Onna Chohoki' (Women's Treasury) which contains a section devoted to the folding of formal wrappers / tsutsumi.

1697 - Japan: A scrapbook album of folded paper tsutsumi, including ocho and mecho butterflies, held in the collection of the Metropolitan Museum in New York, can be dated to the third month of 1697. The album served as the initiation into the art of origata (an early word for origami) for Kikuchi Fujiwara no Takehide by a master of the Ogasawara school of etiquette.

1704 - Japan: Drawing of a kimono decorated with drawings of the takara-bune (similar to the paperfold now known as the Chinese Junk).

1721 - Japan: Publication of the book 'Wakoku Chiyekurabe' (Mathematical Contests) by Kan Chu Sen which includes the earliest known example of a fold and one cut puzzle.

1734 - Japan: Publication of 'Ranma Zushiki' by Hayato Ohoka which contains prints of decorations intended to enhance sliding room dividers. Among these is a print that shows a group of folded paper objects, including the Orizuru (the Crane), Komoso, the Paper Boat, the Sanbo on Legs and the Tematebako, a modular cube developed from six Menko.

1757 - Spain: In a letter sent home to his mother from his school on the Isla Real de Leon, dated 10th July 1757, schoolboy Guillermo Pen wrote 'Con esta estratagema les hago callar; y despues para hacerme amigo de ellas, a unos les hago cometas, a otros barcas, navios, pajaros, y otras muchos cosas, todo de papel.' (With this ploy I silence them; and then to make friends with them, I make kites for some, for other boats, ships, birds, and many other things, all of paper.) His letter can be found in 'Entretenimiento de Los Ninos' by Monsieur Rochon, published in Madrid in both Spanish and French in 1779.

1764 - Japan: Writing of 'Hoketsuki' (wrapping and tying) by Ise Sadatake, also sometimes called the 'Tsutsumi-no Ki', a book about the folding of tsutsumi or ceremonial paper wrappers for food and flowers in the tradition of the Ogasawara school of etiquette.

1765 - England: Publisher John Sayer devised a new kind of fold-out storybook which subsequently became known as Harlequinades.

1797 - Japan: Publication of the Senbazuru Orikata, a book of origami designs, woodcuts and poetry. The designs are created by cutting slits in large squares to divide them into several, or many, smaller, but not completely separate, squares and then folding each of these smaller squares into a paper crane. The cranes remain connected by beak, legs, or wingtip when the design is complete.

1800 - England: A painting by John Hill shows two carpenters in a workshop wearing Carpenters Hats created by folding paper.

There is no direct evidence that these boats were traditional paper boats but it seems likely that this must have been the case. In 1820 Shelley wrote 'Letter to Lady Gisborne', a poem which included the lines: 'And in this bowl of quicksilver - for I / Yield to the impulse of an infancy / Outlasting manhood - I have made to float / A rude idealism of a paper boat:'

1826 - Germany: Mention in Friedrich Froebel's book 'The Education of Man' of two children folding a dwelling house from a large sheet of cardboard, while others are busy folding from smaller sheets of paper all kinds of furniture - tables, chairs, sofas, beds, writing-desk, picture-frames, looking-glasses, etc.
