The Four Elemental Phases of the Moon
Elemental Time
It’s unsurprising that noon and summer would be associated with fire, and by that same logic, the full moon should also be in the same category….Earth, in the opposite direction as fire, therefore corresponds with midnight, winter, and the new moon….Air is the element of new beginnings, youth, increase and creativity. As such, it is associated with spring, the waxing moon, and sunrise…Water is the element of emotion and wisdom, particularly the wisdom of age. It represents a time past the peak of livelihood, moving toward the end of the cycle.
