Dante Alighieri was the first poet that we know of to have used what is known as the terza rima. The terza rima is a rhyming verse stanza form that consists of a three-line rhyme scheme. This chain rhyme follows the pattern ABA BCB CDC DED. Poems written following this structure usually end on a single line or a couplet (DED E or DED EE). In English, terza rima is usually written in iambic pentameter.
