Phanopoeia is Ezra Pound's term for poetry that projects a visual image into the reader's mind. It depends on language that makes us see a scene, object, or action clearly and quickly. Pound contrasted it with melopoeia, which works through sound, and logopoeia, which works through the play of thought and language.
The term is especially associated with modernist criticism, not with a fixed poetic form. Pound's comments about Chinese writing are historically important, but phanopoeia simply means image-making in words.
Example
The lantern lifted its small gold eye
above the harbor,
and every wet rope on the dock
shone like a vein of fire.
