Hello does anyone know of anyone I could contact or where I could look with regard to an explanation of the painting on the front of the Aryeh Kaplan Reader by Rabbi Aryeh Kaplan himself?
Rabbi Aryeh Kaplan was among many things a painter. He mentioned this in his book Jewish Meditation.
This [questionably sourced] article mentions:
His dining room was adorned with a series of bizarre oil paintings. At some point, with no training as an artist, Kaplan decided to refrain from study for a year and devote himself to painting. After the year he stopped and never painted again. Those paintings were the product of his experiment.
At the thirtieth anniversary of his passing, his son started a Facebook page in order to raise money and the like to fund a Sefer Torah in his memory.
On that Facebook page he also posted different pictures and paintings from his father. Here is the post of the [seemingly] original copy of that painting. Maybe he’ll answer you through Facebook?
(It’s no longer an active Facebook page, as far as I can tell)
