hierophant
An ancient Greek priest who interpreted sacred mysteries, especially the priest of the Eleusinian Mysteries.
The exhibition of ancient statues, relics, and symbols, concealed from daily adoration (as in the Catholic festivals of this day), probably, made a main duty of the Hierophant.
An interpreter of sacred mysteries or arcane knowledge.
Poets are the hierophants of an unapprehended inspiration; the mirrors of the gigantic shadows which futurity casts upon the present; the words which express what they understand not; the trumpets which sing to battle and feel not what they inspire; the influence which is moved not, but moves. Poets are the unacknowledged legislators of the world.
One who explains or makes a commentary.
Where it comes from
