The Credence of Skeptics is a solemn poetic form intended to satirize someone's character, originating in The Avarice of Improving. The rules of the form are applied by poets to produce individual poems which can be recited. The poem is two quintains. Each line has five syllables. Every line of the poem has an initial caesura. The fifth line of each quintain uses the same placement of allusions as the second line. The third line of each quintain must expand the idea of the first line.
