South Korea’s national flag – the Taegeukki – is one of the most distinctive around, and is heavily imbued with philsophical meaning. The design itself has changed a little since its first unveiling in the 1880s, though its fundamental elements remain the same: a red-and-blue circle surrounded by four black trigams, all set on a white background. The puritanical connotations of the white are obvious, whereas the circle and trigrams offer greater food for thought. The four trigams make up half of the eight used in the I Ching, an ancient Chinese book of divination. Each can represent a number of different concepts: moving clockwise from the top-left of the flag, these may be read as spring, winter, summer and autumn; heaven, moon, earth and sun; father, son, mother and daughter; as well as many more besides.
The circle is split into the “Yin–Yang” shape, its two halves representing opposites such as light and dark, male and female, day and night. Though coincidental, connections with the divided Korean peninsula are easy to find, with two opposing halves forming part of the same whole – the red half is even on top.
