The 36 Faces
Decans
Each zodiac sign is divided into three 10-degree segments called decans, each with its own planetary ruler. Compare three traditional systems.
Each sign's 3 decans are ruled by the 3 signs of the same element, in order. For example, Aries (Fire): 1st decan = Aries (Mars), 2nd = Leo (Sun), 3rd = Sagittarius (Jupiter).
