The Sienna Truth is a poetic form concerning the future, originating in The Dungeon of Verses. The rules of the form are applied by poets to produce individual poems which can be recited. The poem is a single couplet. Use of assonance and symbolism is characteristic of the form. Forms of parallelism are common throughout the poem, in that certain lines are required to maintain phrasing and they reverse grammatical structures. Each line has five feet with a tone pattern of even-uneven. Every line of the poem has a terminal caesura. The ending of each line of the poem shares the same rhyme. The second line of the couplet presents a different view of the subject of the first line. The first line is intended to express grief over the subject of the poem. The second line is intended to console the audience.
