Chiastic structure, or chiastic pattern, is a literary technique in narrative motifs and other textual passages. An example of chiastic structure would be two ideas, A and B, together with variants A' and B', being presented as A,B,B',A'. Chiastic structures that involve more components are sometimes called "ring structures", "ring compositions", or, in cases of very ambitious chiasmus, "onion ring compositions". These may be regarded as chiasmus scaled up from words and clauses to larger segments of text. These often symmetrical patterns are commonly found in ancient literature such as the epic poetry of the Iliad and the Odyssey. Classicist Bruno Gentili describes this technique as "the cyclical, circular, or 'ring' pattern (ring composition). Here the idea that introduced a compositional section is repeated at its conclusion, so that the whole passage is framed by material of identical content". Meanwhile, in classical prose, scholars often find chiastic narrative techniques in the Histories of Herodotus:

Herodotus frequently uses ring composition or 'epic regression' as a way of supplying background information for something discussed in the narrative. First an event is mentioned briefly, then its precedents are reviewed in reverse chronological order as far back as necessary; at that point the narrative reverses itself and moves forward in chronological order until the event in the main narrative line is reached again. Various chiastic structures are also seen in the Hebrew Bible, the New Testament, the Book of Mormon, and the Quran.

The term chiastic derives from the mid 17th century term chiasmus, which refers to a crosswise arrangement of concepts or words that are repeated in reverse order. Chiasmus derives from the Greek word khiasmos, a word that is khiazein, marked with the letter khi. From khi comes chi. Chi is made up of two lines crossing each other as in the shape of an X. The line that starts leftmost on top, comes down, and is rightmost on the bottom, and vice versa. If one thinks of the lines as concepts, one sees that concept A, which comes first, is also last, and concept B, which comes after A, comes before A. If one adds in more lines representing other concepts, one gets a chiastic structure with more concepts.

Oral literature is especially rich in chiastic structure, possibly as an aid to memorization and oral performance. In Homer's Iliad and Odyssey, for instance, Cedric Whitman finds chiastic patterns "of the most amazing virtuosity" that simultaneously perform both aesthetic and mnemonic functions, permitting the oral poet easily to recall the basic structure of the composition during performances. Steve Reece has demonstrated several ambitious ring compositions in Homer's Odyssey and compared their aesthetic and mnemonic functions with those of several South Slavic songs.

In 1986, William H. Shea proposed that the Book of Daniel is composed of a double chiasm. He argued that the chiastic structure is emphasized by the two languages that the book is written in: Aramaic and Hebrew. The first chiasm is written in Aramaic from chapters 2 7 following an ABC CBA pattern. The second chiasm is in Hebrew from chapters 8–12, also using the ABC CBA pattern. However, Shea represents as "D", a break in the center of the pattern.

Form critic Nils Lund acknowledged Jewish and classical patterns of writing in the Christian Testament, including the use of chiastic structures throughout.
