There is a helpful collection of Virgil resources assembled by David Wilson-Okamura. In fact his selection of links includes so much material that I will list only a few more.

As mentioned on other pages, an essential site for information about, and images of, anything related to ancient Greece is the Perseus Digital Library. Check out the very useful search facility. (If it's down, there are mirror sites in Oxford and Berlin.)

You will have noticed that our text includes no annotations. There is a helpful annotated version of Book II by Andrew Wilson.

Here is an image of Laocoon. This is a Roman copy of a Greek original from c. 200 BC. (I found it here.)
