Woman's Language: Nushu is a phonetic version of Chinese used exclusively by women in the Hunan Province in southern China from some time around the 13th century until the late 19th century. The language arose because most women in that era did not have the same access to formal education as did men. See post for more info.
The Star Gauge (Xinyua Tu) by Su Hui, a Fourth Century Chinese poet and palindromist, is a complex poem woven in silk in five colors, consisting of a grid of 841 characters which can be read forward or backwards, horizontally, vertically or diagonally, resulting in 2,948 different poems. Legend has it that after losing her husband to a concubine, Su Hui composed this poem to lure him back, and it worked. Translation in link.
