Ancient history is broad, very broad. It would be easier if you were slightly more specific. (Time Periods, Cultures , etc. )

Do you want pictures/mosaics from the time period or paintings/illustrations from later periods depicting it?

I have a lot of paintings/images on my computer of Ancient Greek and Roman mosaics, paintings etc.

So do you want 15th century - modern images, or do you want images from that time period?

You can find all of them online through google but you can check [this] (http://imgur.com/a/WlTPl) out to see if this is what you want.

If you want mosaics or some other type of images I could upload them.
