Monody is a poem form inspired by the old Greek odes, and more specifically elegies. It is a poem of grieving, meant to be recited by a single person. As such, monodies do have a tendency to be more personal than other elegies, referencing the feelings of the individual rather than the general opinions of a group.
Idylls are short poems about rural living, but Theocritus’s original idylls were quite long by the standards of modern poetry. This is generally seen as a synonym for pastoral. When the two are differentiated, it is accepted that “idyll” will then refer to poems directly inspired by Theocritus’ writing.
A patchwork poem is a form of found poetry made of lines taken from different sources, and when assembled together they create an entirely new poem. Patchwork and cento are actually words used interchangeably when referring to this poem type. It’s just that patchwork poetry is essentially seen as the “modern” version.
Ekphrastic poetry is a written expression of a visual form of art. In ancient Greece, they use the ekphrasis technique to write about or verbalize momentous events, history, or a work of art. Because ekphrastic poems are a way to creatively articulate art or significant scenes or events, this poem type is usually imaginative, vivid, and quite dramatic.
