In 1903, Japanese artist Mori Yuzan’s wave designs were published in a resource guide for Japanese craftsmen looking to add aquatic motifs to their wares. The three-volume series, titled Hamonshū, includes variations on contained and free-form wave patterns suitable for embellishing swords, religious objects, and ceramics. The collection has recently been digitized and is available for free on Internet Archive, a non-profit digital library of free books, movies, and software. (via My Modern Met)
