The Truth of Poetry is a poetic narrative intended to make an apology concerning someone's character, originating in The Robust Berry. The rules of the form are applied by poets to produce individual poems which can be recited. The poem is a single tercet. Use of metaphor is characteristic of the form. A form of parallelism is common throughout the poem, in that certain lines reverse grammatical structures. Each line has four syllables. The second line of the tercet is required to maintain the phrasing of the first line.
