Word of the day.
"Symbology," as no doubt people will be saying after The Da Vinci Code appears in theaters on Friday, is not an academic discipline. No one studies it. As far as the academic community is concerned, "symbology" is not a word. "Symbolism" is, and it describes the use of symbols as representation or allegory. To study symbols is not "symbology."
The study of symbols and symbol systems is semiotics. I know I promised a friend in Google Chat to post about other topics, but, what the hell, this is also about movies and popular culture.
So. Now that we're clear, please go about your business.
