You have mentioned the charactes have different names. Am I right in thinking the charactes are named like this?
- Agron = Agron
- Spartacus = Spartacus
- Crixus = Crissos
- Gannicus = Gannicus
- Claudio Glabro = Claudius Glaber
- Naevia = Naevia
- Lucretia = Lucrezia
- Ilithyia = Ilizia
I only don't know what the Italian names of Crassus, Tiberius, Caesar and Nasir are. If I would know them, I could start creating your main page. :)
By the way, shouldn't it be better to create a template for the infobox of the episodes? In my opinion the source code of them doesn't look clearly. If you don't know how to create a template, I can help you, of course. :)
Edit: So, I have created a template for the episodes now. You can see it here. I have tried to create it in Italian, but I'm very sure there are many mistakes in the Italian language.
