History of origami:Composed of the Japanese words oru (to fold) and kami(paper and god), origami has a rich and complex history that spans culture, class, geography, and unique spiritual connection. Origami can be found outside most temples in Japan as a sign that a god resides within.
Classical and Traditional Origami Paper was first invented in China around 105 A.D., and was brought to Japan by monks in the sixth century. Handmade paper was a luxury item only available to a few, and paper folding in ancient Japan was strictly for ceremonial purposes, often religious in nature.
By the Edo period (1603–1868), paper folding in Japan had become recreational as well as ceremonial, often featuring multiple cuts and folds. It came to be regarded as a new form of art that was enabled by the advent of paper both mass-produced and more affordable. Written instructions for paper folding first appeared in 1797, with Akisato Rito’s Sembazuru Orikata, or “thousand crane folding.” In 1845, Adachi Kazuyuki published a more comprehensive compilation of paper folding with Kayaragusa; by the late 1800s, the term for paper folding had morphed from orikata (“folded shapes”) to origami.
Europe also has a tradition of paper folding that dates back to the twelfth century or before, when the Moors brought a tradition of mathematically based folding to Spain. The Spanish further developed paper folding into an artistic practice called papiroflexia or pajarita. By the 1800s, kindergarten-aged children in Europe and Japan were learning paper folding.Make an origami boat and go float it in the rain gutters!
He was self-taught. Leonardo was not allowed to go to school because his parents were not married.
Only 24 of his paintings remain. Most of what we know about Leonardo’s art and inventions is from his notebooks.
He kept dozens of notebooks, and used every inch of the paper. Often times different ideas and notes appear together on the same page.
There may have been as many as 13,000 pages of notebook entries, but over half of them are lost.
He wrote backwards in his notebooks. Maybe because it was fun for him, maybe because he was left-handed and didn’t want to smudge his ink, or maybe to help keep his ideas secret.
