Being one of the four classical elements in alchemy along with fire, water and air, the Earth is symbolized in alchemy by a downward triangle divided by a horizontal line crossing through it. Plato associated properties like cold and dryness with the Earth symbol while brown and green are the colors representing the element.

In alchemy, the element of earth is associated with stability, groundedness, and physical matter. It is often represented by the alchemical symbol of a downward-pointing triangle with a line through it. This symbol can also represent the feminine, receptive aspect of nature.
