That may be so, Ruggercat, but artistic movements in general tend to cycle through three distinct phases. The first is a simple, straightforward period where realism is appreciated, but perfection is not a goal. Creative work coming from this period tends to be unremarkable, but at least has respect for the history of the craft.
The second phase is the classical period discussed in the article. Artists strive for perfection in every aspect of their work, and for a while they come very close to achieving it. We consider Mozart to be a classical composer because his music is technically flawless. A visual artist working during a classical period creates ideal images and balanced compositions. But it is nearly impossible to maintain perfection for more than a few years.
That's where the third phase comes in. Artists are allowed to indulge in their passions and not worry so much about perfection. This is where romance and experimentation take over. Neoclassicism is sometimes seen as an attempt to re-establish classical values during an otherwise romantic or baroque period.
