The eight trigrams, or bagua, are the three-line figures built from broken and unbroken lines that combine in pairs to form the sixty-four hexagrams of the I Ching. Each carries a name, a natural image (heaven, earth, thunder, water, mountain, wind, fire, lake), a family member and a direction. Two arrangements are standard: the Earlier Heaven sequence attributed to Fu Xi and the Later Heaven sequence attributed to King Wen, which is the one used in feng shui.

The trigram system belongs to the Ten Wings commentaries of the Warring States and Han periods, later than the hexagram text they interpret. 1

The Eight Bagua

The eight trigrams, or bagua, are the three-line figures, each line broken or unbroken, that combine in pairs to form the sixty-four hexagrams of the I Ching. Each trigram has a name, a natural image (heaven, earth, thunder, water, mountain, wind, fire, lake), and a web of associations: a family member, a direction, a season, an element of the wu xing.

The eight are arranged in two classic sequences, the Earlier Heaven (Fu Xi) and Later Heaven (King Wen) orders, which place them differently around the compass and are used for different purposes in cosmology, divination and feng shui.

A Cosmological Alphabet

The trigrams function as a small alphabet of cosmic qualities from which the larger vocabulary of the hexagrams is built, and they carry meaning in their own right, in feng shui the bagua maps the trigrams onto the areas of a building or site, and in Chinese cosmology they organise the relations of yin and yang.

The atlas gives each trigram its image, family and directional and elemental associations, and its two classic arrangements. The hexagrams built from them are treated in their own category, and the trigrams connect to the wider Chinese systems under Eastern Systems.
