A triolet (, ) is almost always a stanza poem of eight lines, though stanzas with as few as seven lines and as many as nine or more have appeared in its history. Its rhyme scheme is ABaAabAB (capital letters represent lines repeated verbatim) and often in 19th century English triolets all lines are in iambic tetrameter, though in traditional French triolets, from the 17th century on, the second, sixth and eighth lines tend to be iambic trimeters followed by one amphibrachic foot each. In French terminology, a line ending in an iambic foot was denoted as masculine, while a line ending in an amphibrachic foot was called feminine. Depending on the language and era, other meters are seen, even in French. The first, fourth and seventh lines are identical, as are the second and final lines, thereby making the initial and final couplets identical as well. In a traditional French triolet, the second and third non-repeating lines rhyme with the repeating first, fourth, and seventh lines, while the non-repeating sixth line rhymes with the second and eighth repeating lines. However, especially in German triolets of the 18th and 19th centuries, one will see this pattern often violated. History The triolet is a close cousin of the rondeau, the rondel, and the rondelet, other French verse forms emphasizing repetition and rhyme. The form stems from medieval French poetry and seems to have had its origin in Picardy. The earliest written examples are from the late 13th century. In this century, possibly the earliest surviving triolet is from "Li Roumans dou Chastelain de Couci et de la Dame de Fayel", where it is referred to as simply a song ("chanson"). Seven more easily datable 13th century triolets (also known as songs) are to be found in "Cléomadès" by Adenet le Roi. In the early 14th century, the songwriter, Jean Lescurel, wrote many triolets under the term of rondel. Lescurel was followed by Guillaume Machaut and, at the end of the century, by Jean Froissart. In the early 15th century, Christine de Pisan experimented with a slightly abbreviated seven-line variation of the triolet which she, like her predecessors, also termed a rondel. Toward the end of this century, Dutch language triolets (though designated as rondels) by Anthonis de Roovere appear. Also, at the end of the 15th century, the term triolet appears for the first time. It was probably first so designated
