Traditional Convex Bagua Mirror – Eight Trigrams
A traditional Chinese decorative object reflecting the cultural heritage of the Bagua, the Eight Trigrams and classical Chinese cosmology.
The Convex Bagua Mirror is a distinctive octagonal decorative plaque featuring a central outward-curving mirror surrounded by the eight trigrams, traditionally associated with the Yijing (I Ching), or Book of Changes.
With its red octagonal frame, green border and gold-coloured trigram markings, this piece reflects a longstanding tradition of incorporating cosmological imagery into Chinese architectural and decorative objects.
Traditionally displayed outside buildings, Bagua mirrors are associated with Chinese folk customs concerning the relationship between a dwelling and its surrounding environment.
The Bagua and the Eight Trigrams
The Bagua (八卦), meaning Eight Trigrams, is an ancient system of eight symbolic figures composed of three continuous or broken lines.
Each trigram represents a different combination of yin and yang and is traditionally associated with aspects of nature, family relationships and the changing patterns of the universe.
The eight trigrams are:
-
Qian (乾) – Heaven: Creativity, strength and the father.
-
Kun (坤) – Earth: Receptivity, nourishment and the mother.
-
Zhen (震) – Thunder: Movement, awakening and the eldest son.
-
Xun (巽) – Wind: Gentleness, penetration and the eldest daughter.
-
Kan (坎) – Water: Depth, danger and the middle son.
-
Li (離) – Fire: Clarity, illumination and the middle daughter.
-
Gen (艮) – Mountain: Stillness, stability and the youngest son.
-
Dui (兌) – Lake: Joy, openness and the youngest daughter.
The Bagua has played an important role in Chinese philosophy, cosmology and traditional Feng Shui studies.
The Early Heaven Bagua Arrangement (先天八卦)
The eight trigrams displayed around this mirror follow the Early Heaven Bagua Arrangement, traditionally attributed to Fu Xi, a legendary figure in ancient Chinese culture.
Also known as the Xian Tian Bagua, this arrangement represents an idealised state of cosmic balance through the complementary relationships of Yin and Yang.
At the top is Qian (乾 ☰), representing Heaven, while directly opposite at the bottom is Kun (坤 ☷), representing Earth.
The remaining trigrams form complementary pairs:
-
Dui (兌 ☱) and Gen (艮 ☶) — Lake and Mountain.
-
Li (離 ☲) and Kan (坎 ☵) — Fire and Water.
-
Zhen (震 ☳) and Xun (巽 ☴) — Thunder and Wind.
These relationships illustrate the traditional Chinese philosophical understanding of complementary forces and the interconnected patterns of nature.
The Early Heaven arrangement is particularly significant in the study of Chinese cosmology and traditional Feng Shui theory.
Traditional Cultural Significance
In Chinese folk customs, Bagua mirrors featuring the Early Heaven arrangement are traditionally associated with the symbolic redirection of unfavourable external influences.
The convex mirror at the centre reflects a wider field of view, while the surrounding trigrams express the traditional philosophical concepts of Yin, Yang and cosmic order.
The object therefore brings together Chinese cosmological imagery, traditional craftsmanship and longstanding architectural customs.
The Convex Mirror
At the centre of the octagonal plaque is a convex mirror, distinguished by its outward-curving reflective surface.
Unlike a flat mirror, a convex mirror provides a wider field of reflection and produces a reduced image of its surroundings.
In traditional Chinese folk Feng Shui customs, convex Bagua mirrors are associated with the symbolic redirection of unfavourable external influences, particularly those attributed to certain architectural features or surrounding structures.
These associations reflect traditional cultural beliefs rather than scientifically established effects.
Traditional Use & Display
Bagua mirrors are traditionally displayed on the exterior of buildings, commonly above entrances or facing particular external architectural features.
In Chinese cultural traditions, the placement of such mirrors may be associated with concepts such as Sha Qi (煞氣), a term used in certain Feng Shui interpretations to describe unfavourable environmental influences.
The object is best understood as an example of Chinese folk heritage and traditional architectural customs.
For those interested in Chinese history, the Yijing and traditional decorative arts, it also provides an accessible visual introduction to the Eight Trigrams.
