A ten-line poetry or stanza. Also called a dialogue, dialogue, disputation, essay. Decasstiches were popular in medieval England and later became known as "ten-line poems" or "dialogues." The name comes from the fact that each line of the poem contains 10 syllables. They are different from modern poems because they do not have a structure such as sonnets or villanelles. A decasstiche consists of 10 lines which vary in length depending on how much space the poet wants to fill. These lines usually have three parts: an opening phrase, a middle section, and a closing phrase. There are different types of decasstiches. Some include only nouns while others include both nouns and adjectives. Some focus on action while others discuss ideas. There are also sacred and profane decasstiches. Sacred ones are used to praise God while profane ones are used for entertainment purposes. One famous sacred decasstiche is "The Divine Comedy" by Dante Alighieri. It is made up of three parts: hell, purgatory, and heaven.
