The most widely used astrological correspondence for the Hierophant card is the Zodiac Sign of Taurus. And this is definitely one of the correspondences that, for me personally, just doesn’t work all that well.
On the one end of the pairing, The Hierophant is a spiritual teacher and go-between, someone who – at least in theory – dedicates their life to helping members of their community in connecting with the Divine. The Hierophant provides structure, support, tradition, and access to accumulated knowledge.
Meanwhile, the other end of the pairing is Taurus. Using an Earth Sign isn’t a bad notion to start with: The Hierophant is in some sense trying to bring the Celestial down to the earthly plane. Taurus, though, doesn’t feel like the best specific choice to me as far as Earth symbols go. Traditionally linked with Venus, the Sign of Taurus has much to do with concepts such as beauty, peace, possessions, sensual pleasures. I’ve heard the argument put forth that a Hierophant is someone you’d seek counsel from in the event that you had issues revolving around Taurus themes, such as materialism or overindulgence in pleasures of a worldly nature…but I guess I prefer my symbolic linkages to be based on affirmative correlations. That is, I’d rather use an astrological symbol that can serve as a sort of synonym for The Hierophant’s presence, not one that flags The Hierophant’s absence.
As with The Emperor’s case, I personally again feel that some reference to Saturn or Capricorn might be the better way to go for this card…
