The brilliance of spontaneous metered poetry, is that is seems to have been conceived and designed, all at once, beyond linear time, before being produced sequentially from the lips of the poet. The heap of cotton was already there, before the spinning wheel turned it into lines of thread. The nectar resided in its mouth, before the worm pronounced its silk.
The reverse-engineering of poetry, on the other hand. That is, the attempt to compose according to a derived pattern, entirely lacks this spectacular feature.
