The orgininal author is named Sandris and you can go to his original topic there http://forums.civfanatics.com/downloads.php?do=file&id=11004. It was hard to convert because the shadows were pink and the legion wasn't able to take his team colour. So the new colours aren't perfect, I know but I think it's quite good. So I advise you to use red yellow or orange player colour for the legionnairy.
