FWIW: Its more that I applied my analytic approach to art, and that it was the first subtantive work I did, demonstrating anything can be disambiguated into first causes.
Knowing how to analyze art is just like any other set of measurements we have produced.
However, some of those measurements require knowledge of the technology and materials used in the producdtion, the skill of the craftsman in producing it, the time and place of that production, the movement (fashion) that it was influenced by, and whether or not its a canonical example of that movement.
Interpreting the content and messaging does require some knowledge of history and usually of mythology. In other words some art, like some plays and some literature is conceptually dense.
So, while we can state the science of evaluating art, and in doing so provide a map for investigating any given work, set of works, movement, etc. But it still takes a bit of work from there.
However, like weapons training, the first 20% gets you 80% of the way there. 😉
