It is good to have badges for important authors. At the moment we have the tag horace, but I created the tag horatius today when I asked about the same poet. This is because I strongly prefer using original Roman forms of the names of authors instead of the English ones — that is why I write Horatius instead of Horace.
Whether or not we decide to have our tags in Latin, I think the author tags should be in Latin. Some authors have different names in different languages (Horatius, Horace, Orazio…) so some users may be unaware of the English version. On the other hand, everyone who knows an author should know them by their original name. For me it took a considerable amount of time to figure out who Horace, Virgil and Homer are, although I had learned about Horatius, Vergilius and Homeros.
I propose a policy to have all author tags in their original form. Do you agree we should do this? It might make sense to keep the English versions as well but make them synonyms to the main tag. Another option is to edit all such tags to the classical form. What would be a good way to go about this?
