And my point is that it's a label on a cyclical trend. But sure, he wanted to reason about romanticism specifically. He cuts off very early in the new century, and the romanticism presaged a 50year cycle of revolution and revolt against the congress of Vienna. The tide swung back and forth.

Not so sure about that. Romanticism isn't related to Millinarianism conceptually or otherwise. The former was a re-adoption of a hollistic medieval stance on life and nature.
If you mean "some cultural things change every now and then, so a trend changing is nothing new", maybe, but it's a much smaller claim than that we see a rebirt of Romanticism specifically.
