Scenes is historical fiction. Understanding the historical pieces of the play can be exponentially helpful. On my first read of Scenes I had no idea that this show was based upon the work of an artist named Artemisia Gentileschi. To understand the impact that a female artist had post-renaissance and during the Baroque period of Italy is wonderous. These links will hopefully set the history behind the play in a light that previously was dim. Many of the links below cover her life and her art, but simply that is what Artemisia was really about: her art in her life.
The Life and Art of Artemisia

This website does almost a slide show of Artemsia's paintings, when they were painted and what was going on in Artemesia's life when she did the painting.
Obligatory Wikipedia website
http://en.wikipedia.org/wiki/Artemisia_Gentileschi
As with most Wikipedia sites, it is more of an overall projection of Galactia. It has a very in depth biography of her life. It also has an interesting section about her and her relationship with popular culture that might be beneficial.

This has a biography on her, other websites about her painting, an explanation of her paintings, and interestingly has the first information that I have found about a possible rape of Artemisia. It lastly goes into an explanation of the movie about her.
