A Chinese compass consisting of a bowl covered with glass and containing a dry-pivot needle. The needle points south. The north-south direction is indicated by a piece of metal over the glass. Around the rim are 24 Chinese characters indicating the traditional azimuthal directions in 15 degree increments. These characters come from a row found on all Chinese geomantic compasses. It is believed that the Chinese mariner's compass developed out of the geomantic one. Together the characters consist of the 20 cyclical characters and four gua (trigrams). These characters are arranged in the Zheng Zhen ('correct needle') position (i.e. the north-south direction). Beginning with the character in the South position and moving clockwise the characters are: Wu, Ding, Wei, Kun, Shen, Geng, You, Xin, Xu, Qian, Hai, Ren, Zi, Gui, Chou, Gen, Yin, Jia, Mao, Yi, Chen, Xun, Si and Bing. Although the characters do refer to directions, the characters in the North, South, East and West directions are not the characters or the literal translations for these directions, but are the traditional characters from the geomancer's compass. The character indicating the direction 'South' is red, while all other characters are black.
