Iconology is the study and interpretation of symbols and images within their cultural and historical contexts. It aims to understand the deeper meanings represented in works of art beyond their literal subject matter. Key figures who developed the field include Aby Warburg, who emphasized the transmission of classical imagery over time, and Erwin Panofsky, who established a three-level method of iconographic analysis moving from basic description to cultural and historical interpretation. The systematic study of iconography flourished in 16th century Italy and was advanced in the early 20th century by Panofsky and others who brought more rigorous methodologies to the classification and interpretation of visual symbols and themes.
