The document discusses the personal and cultural value of self-portraits created by artists. It notes that since the 15th century, nearly every artist across different mediums has explored self-portraits as a way to examine their own psyche or simply because they are the most available model. By viewing these self-portraits, viewers can gain insight into how artists see themselves and their different "selves", and better understand their personalities and what they wish to show or hide.
