" N o one knows when tangrams originated. The earliest reference known is a book published in China in 1803. Its title, The Collected Volume ofPatterns of the Seven-Piece Puzzle, suggests earlier books. Most scholars believe the game originated in China about 1800, became an Oriental craze, and then spread rapidly to the West. The earliest Western books, says Read, were little more than copies of Chinese rice-paper booklets.

Some of the marketed variants are pictured in Professor Hoffmann’s pioneer book on mechanical puzzles, in Creative Puzzles of the World by Pieter Van Delft and Jack Botermans, and in Puzzles Old and New by Jerry Slocum and Botermans. Of special interest, because it predates any known Chinese publication, is a 32-page book published by Kyoto Chobo in Japan in 1742. It gives forty-two patterns to be made with the seven pieces obtained by dissecting a square as shown in Figure 24. The book’s title translates as The Ingenious Pieces of Sei Shonagon.
