An online computer application residing in a dedicated web site to teach art history: especially stylistic connections and influences between broad art historical periods and among individual artists and schools. For example, a person enters the name of Rembrandt. A visual cluster of his works appears, arranged by different media or chronologically. Then, when the user clicks on an individual work, a different cluster would appear with that work at the center--self-portraits, for example. Clicking on any of the self-portraits in the new cluster would deliver references to articles, or it could be "tuned" to show works that influenced the portrait or which it influenced. The user could follow these new paths to learn about other works, other artists, periods, movements. Unexpected relationships would emerge. I have identified the technology. I can assemble the database at my own expense (I have edited major art textbooks for McGraw-Hill) but I need funding to purchase the technology.
