Calligrammes: Poems of Peace and War 1913–1916, is a collection of poems by Guillaume Apollinaire which was first published in 1918. Calligrammes is noted for how the typeface and spatial arrangement of the words on a page plays just as much of a role in the meaning of each poem as the words themselves – a form called a calligram. In this sense, the collection can be seen as either concrete poetry or visual poetry.
