History of Origami in the East and the West before Interfusion

When Oppenheimer wrote the foreword to How to Make Origami, it was widely believed that paper was invented by the Chinese eunuch Cai Lun (also alphabetized as T’sai Lun) in 105 ce. However, much older paper has been unearthed from some tombs of the Western Han Dynasty (206 bce8 ce). The oldest piece, which was discovered at Fan Ma Tan in 1986, is estimated to have been made in the middle of the second century bce [Komiya 01].
