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.

Chaldean (Traditional) Triplicity (Ptolemaic) Egyptian (36 Faces)

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).
