Looking for Vatican Vergil help

[The Cooler King]

Hey, guys. I'm working on a paper for my Art History class, and I am looking for good, scholarly resources on the Vatican Vergil. Almost every source I've been able to find (including the books and online articles I've found) have been by one author, David H. Wright. I'm looking for other authors and other perspectives, mainly relating the the Vatican Vergil's place in history and its artistic merits. Does anyone have any suggestions? I'd like to expand my citations page beyond "Wright, David"! Articles (especially articles in scholarly journals), books, websites-- anything would be welcome.

Thanks in advance for any help!
