This is my essay title and if possible I'd like a little bit of help starting it! I need a good structure (would stating the similarities and the differences be a good structure?) and argument (although I'm sure after working out my structure I can devise a decent argument). I also need to know what these differences and similarities were? I'm assuming the title refers to areas such as forums, ampitheatres etc. so I thought this would be the best place to ask. Thanks a lot for any help you can offer me! LookAlive
