was first invented by Cai Lun during the Eastern Han Dynasty era. In the 6th century, Buddhist monks carried paper to Japan. The earliest document showing paper folding is a picture of a small paper boat in an edition of Tractatus de sphaera mundi from 1490 by Johannes de Sacrobosco. However it is very likely that paper folding originated much earlier than that in China and Japan for ceremonial purposes. In China, traditional funerals include burning folded paper, most often representations of gold nuggets. This practice probably started when papers gradually become popular and cheaper in China, and it seems to have become quite common during the Song Dynasty. In Japan origami butterflies were used during the celebration of Shinto weddings to represent the bride and groom, so ceremonial paperfolding had probably already become a significant aspect of Japanese ceremony by the Heian period of Japanese history. It is possible that paper folding came to Japan from China when paper was introduced but there is no evidence for this. The paper folding of China has typically been of objects like dishes, hats or boats rather than animals or flowers of Japan. The Japanesetreasure ship model is probably derived from the Chinese model which uses an unusual fold that may have been inspired by the folded sychee, however in general the models of the two countries are quite different.
Significant early publications
Maying Soong's 1948 book, The Art of Chinese Paper Folding, helped popularise recreational paper folding in the 20th century, and was possibly the first to distinguish the difference between Chinese versus Japanese paper folding – where the Chinese focus primarily on inanimate objects, such as boats or pagoda, the Japanese include representations of living forms, such as the crane. It contains a number of simple traditional designs, some of which are also found in the traditions of other countries. A number of the models are folded from the blintz base, a form also common in traditional European and Japanese paper folding. The Old Scholar's Hat is among the old Chinese models found in this book. and the main quote of this book.
Three dimensional origami
In 1993, a group of Chinese refugees were detained on the ship Golden Venture and held in an American prison, where they began making elaborate models combining traditional Chinesemodular paperfolding with a form of papier-mâché ; these models were given to those helping the refugees and sold at charity fundraisers. Media coverage of the refugees helped popularize traditional Chinese modular folding worldwide, which became known as 'Golden Venture folding'. This type of modular folding is often done with Chinese paper money. Triangles are folded from multiple pieces of 1:2 aspect ratio paper, and connected by inserting a flap of one triangle into a pocket on the next. Popular subjects include pineapples, swans, and ships. This form of modular origami is commonly referred to as '3D origami'. .
