I have a project on the early Christian catacombs. I have to describe the elements of (line, shape,value, etc)and compare these catacombs to Byzantine and Islamic architectural structures of the same time. Can anyone help me find some pictures or articles about theses catacombs?I know the Byzatine era had the San Vitale and the Islamic era created the Hagia Sophia but I can't find any significant Early Christian creations. Please Help?!

Did you notice how BobPursley did that?

He went to http://www.google.com and clicked on the word Images above the search box. Then he entered his search terms (in this case, early Christian catacombs), and hit Enter.

You can do the same for anything you are looking for images for.
