Obelisk and Angel

I failed trigonometry in college. But while I was taking notes I made a doodle in the margins that later became this painting. (Just for the record: I missed the first class session where the students were told that they could not use a calculator. Besides, I had just spent $75 on an advanced calculator and I was determined to use it! I could not imagine a scenario where anyone would not take advantage of a calculator if they could. However, my professor did not see it that way. He was about 70 years old in 1977 and he could not imagine anyone using a calculator. His opinion won out on the registrar's report.)

While I was interested in algorithms to a point, I was more interested in the experiment of combining abstract concepts with surrealism. The "Obelisk and the Angel" was one of those experiments. The obelisk and the face of the angel were rendered in an abstract form, while the remainder was rendered in a surrealistic form. The doodle was originally drawn with a blue ball point pen, the look of which is retained in the image of the obelisk. The hand is threatening to keep the angel from ascending beyond the height of the obelisk. The profundity of which escapes me for the moment. Any Freudian suggestions?

The "Obelisk and Angel" was painted on canvas with oils.
