It’s interesting that similarities can be seen between religious art, art that was produced by older cultures, the psychedelic art movement and art brut.
A lot of it seems to reflect on something that’s less a cultural phenomenon but more innate, more of an intuitive understanding or identification of form: shape, structure, repetition, balance.
I’m no psych major but it’s interesting in how it possibly relates to the structure of the mind and how it translates into conscious experience.
