What a fantastic idea - Brokeback Mountain is so rich with symbolism for this. What did we decide which card the Mountain itself would be? I see the mountain as setting everything in motion, making the beautiful relationship betweent Jack and Ennis possible, watching over them, blessing them, and a refuge for them. That's like a High Priest, isn't it? This card is the bridge between Heaven and Earth - I have always seen Jack as "the Sky" all in blue, and Ennis "the Earth" in earthy colors, and their natures fit that as well. Just my first thoughts -
According to Wikipedia, Hierophant literally means "the one who teaches the holy things", and I can't think of anything more holy than bringing two souls together to love as Ennis and Jack were.
"Some authorities say that the Hierophant generally represents assistance, friendship, good advice, alliances (including marriages), and religious interests. Reversed; it often refers to bad advice, lies, and persecution.
Others say that it represents the first level of understanding. When it appears in a tarot spread, it is a warning to the Querant to reexamine his or her understanding of the meaning of things; of the structure of the world; of the powers that be. Watch out for hypocrisy."
Just some second thoughts!
