This person is holding up a light for those lost on the mountain, and possibly offering hospitality, although I don’t see how hospitality is possible, when she’s obviously standing on a patch of ice the size of a dinner platter. This is a card for the non-conforming person, the non-neurotypical person, who may in their own way be sociable but just not immediately, or not in the same room with you.
For people who don’t enjoy being touched; for people who are so easily made angry, or frightened, or despairing, that they avoid contact with other human beings. For people who are sociable but whose mode of being causes discomfort to the inhumane.
Aesthetic aside: The Hermit gives away Colman’s training as a backdrop painter. There is not a breath of wind; therefore one possible interpretation is that we are on a metaphorical stage, a different level of existence.
Or else we’re very high.
(Alan Tudyk K2SO voice: Very, very high.)
Yes, this is the weed card. (If you want to read Judaism into it because of the Star of David hidden in the lamp, you can, but the longer iconographic tradition for Judaism is the menorah, which has the distinct advantage of not being associated with various genocides; sadly there’s nothing like it in the Rider Waite tarot illustrations, unless you squint very hard at the 5 of Pentacles.)
Close examination of the image yields a starting discovery; that is not an old man. It is a non-binary person wearing a prop beard. Don’t believe me? Check out the Ten of Pentacles. Colman knew how to paint old with a few telling lines. This is not an oversight. The Tarot is full of casual gender-swapping. If you really think you know what’s underneath those clothes, you may be wrong.
Isolation because you’re not the same as other people. This is a person holding up the light of their own truth. This is also a card for actors, who wear the skin of someone they are not, and scale heights of emotion in challenging ways.
