Authors of Piyyut

Authors of piyyut are known as "paytanim" (singular: "paytan"). "Piyyut" is Jewish liturgical poetry, in Hebrew or occasionally Aramaic.
The earliest authors of "piyyut" did not sign their names in acrostics, nor do manuscripts preserve their names. The earliest "paytan" whose name is known is Yosé ben Yosé, usually dated to fifth-century Palestine; he did not sign his name in his work, but copyists of manuscripts preserved it along with his work. Starting in the sixth century, "paytanim" began to sign their work.
