As far as I'm aware, that hasn't happened yet. The King does not call the city anything other than "the city" or "The Acropolis."In the rules, I wrote:...However, a court of all the gods can be set up if established by a 2/3 vote of all the gods. Whichever god becomes the titular head has the honor of naming The Acropolis. In the grand scheme of things, however, this doesn't mean all that much.
In light of current events, I'm going to strike this rule. There will be a contest at a later date to determine the name.
