Initially a prayer or supplication used in formal and religious processions, the litany has been more recently adopted as a poetic form that catalogues a series. This form typically includes repetitious phrases or movements, sometimes mimicking call-and-response. Examples explicitly noted as litanies include "Equestrian Monuments (A Litany)" by Luis Chaves, "Litany in which Certain Things are Crossed Out" by Richard Siken, and "Knitting Litany" by Cory Wade. Others such as Ginsberg’s “Kaddish” sustain the form’s elements throughout.
