Paeon (prosody)
In prosody a paeon (or paean) is a metrical foot used in both poetry and prose. It consists of four syllables, with one of the syllables being long and the other three short. Paeons were often used in the traditional Greek hymn to Apollo called paeans. Its use in English poetry is rare. Depending on the position of the long syllable, the four paeons are called a first, second, third, or fourth paeon.
The cretic or amphimacer metrical foot, with three syllables, the first and last of which are long and the second short, is sometimes also called a paeon diagyios.
