A concrete poem or a shape poem is a type of poetry in which the words are arrange in a shape to tell the subject of the poem. This form of poetry goes back to Greek Alexandria in 300 B.C., when poems were written to be presented on objects like an ax handle, an egg, or an altar. In visual poetry the importance of images and illustration is evident, but in concrete poetry the letters, words, and the way the words are arranged makes meaning. The main typographic elements like style, size, weight, width, format and even the way that is printed can tell the meaning. It creates meaning as a whole compared to other forms of poetry.
