Gongorism is an ornate, highly mannered poetic style associated with the Spanish poet Luis de Góngora. It favors elaborate imagery, dense allusion, unusual word order, and rich verbal decoration, sometimes to the point of obscurity. The term is often used critically for poetry that seems deliberately extravagant or difficult.
Example
Moon-silvered lilies, in a crystal hush,
Unfold their jeweled silence over dusk;
The river, clothed in emerald and gold,
Bends like a serpent through the twilight's dust.
