The character, modes, and forms of artistic expression in any epoch are in many ways governed by prevailing intellectual and philosophical points of view. What is considered ‘ good taste ’ by the patron of painting, poetry or music will often seem quite incredible to future generations because intellectual bases of perception and appreciation change so inexorably and often so quickly. If the final judgment about what is satisfying (not to mention ‘ beautiful ’) in a work of art must finally be left to each individual to decide for whatever reasons he feels important, this in no way alters the fact that a work of any period can be seen to exhibit aspects that are characteristic of its creator and audience. By studying a selection of works from a historical period, we are able better to understand not only the works themselves, but at least some particular characteristics of those who produced them, and those for whom they were intended. In a comparative study of the arts we will most quickly reach productive ends using what Erwin Panofsky terms an Iconological approach, a search for ‘ intrinsic meaning and content ’. This angle of vision looks to underlying principles to reveal important generalizations about attitudes of nations, periods, classes, or religions, or philosophical persuasions ‘ unconsciously qualified by one personality and condensed into one work ’. The scholar's work becomes synthetic, rather than just analytic. In the search, one must recover and ponder the ‘ intrinsic meaning ’ of every document of civilization available which relates to the work under consideration. Panofsky mentions specifically the areas of politics, poetry, religion, philosophy, and social tendencies of personality, period and country.
