Defying possible charges of anachronism, I will propose that the term "multiverse" – applied to the period from Copernicus to Newton – permits us to discern more clearly how cosmological thinkers occasionally embedded (rather than merely displacing or replacing) older models of our universe within newer versions of the whole shebang. It also saves us from the incoherence of applying "universe" to multiple entities of different scales, and of calling something that is perhaps mainly chaotic a "cosmos."
