The Sunocdeth Renaissance was the historical period during which Roduram reproductive practices were revolutionized following the mass publication of Sunocdeth, Dar/Za'i's writings on the topic. The year of their publication is used as the basis of the commonly used calendar era, "AR" (After the Renaissance), with years before that date labeled "BR" (Before the Renaissance). A common misunderstanding is that the era begins with the birth of Sunocdeth, but scholars generally agree that Za'i birth occurred in either 37 BR or 44 BR.
