I see the point but I don’t think I agree. I don’t think we can blame The Divine Comedy for being *too* good that it managed to codify or vaunt Florentine dialect into a generally used form of Italian. Nor does he deny the beauty and use cases of other dialects in D.V.E. And the use of a common Italian (as opposed to Latin) allowed for a much greater portion of the populace to have access to the beauty and ideas that inhere in The Divine Comedy. I think of it as Latin = Closed-Source Protocol, whereas Italian = Open-Source Protocol.
