Mandaeism or Mandaeanism (Arabic: mndy'y@ Manda'iyah) is a gnostic religion with a strongly dualistic worldview. Its adherents, the Mandaeans, revere Adam, Abel, Seth, Enos, Noah, Shem, Aram, and especially John the Baptist. The Aramaic manda means "knowledge", as does Greek gnosis. According to most scholars, Mandaeaism originated sometime in the first three centuries AD, in Mesopotamia.

The Mandaeans have a large corpus of religious scriptures, the most important of which is the Ginza Rba or Ginza, a collection of history, theology, and prayers.  The Ginza Rba is divided into two halves--the Genza Smala or "Left Ginza," and the Genza Yemina or "Right Ginza". By consulting the colophons in the Left Ginza, Jorunn J. Buckley has identified an uninterrupted chain of copyists to the late 2nd or early 3rd century CE. The colophons attest to the existence of the Mandaeans or their predecessors during the late Arsacid period at the very latest, a fact corroborated by the Harran Gaweta legend, which says that the Mandaeans left Judea after the destruction of Jerusalem in the 1st century CE, and settled within the Arsacid empire. Although the Ginza continued to evolve under the rule of the Sassanians and the Islamic empires, few textual traditions can lay claim to such extensive continuity.  Other important books include the Qolasta, the "Canonical Prayerbook of the Mandaeans," which was translated by E. S. Drower. and here One of the chief works of Mandaean scripture, accessible to laymen and initiates alike, is the Drasa D-Iahia "The Book of John the Baptist" (text; German translation), which includes a dialogue between John and Jesus. In addition to the Ginza, Qolusta, and Drasa, there is the Divan, which contains a description of the 'regions' the soul ascends through, and the Asfar Malwashe, the "Book of the Zodiacal Constellations." Finally, there are some pre-Muslim artifacts which contain Mandaean writings and inscriptions, such as some Aramaic incantation bowls.  The language in which the Mandaean religious literature was originally composed is known as Mandaic, and is a member of the Aramaic family of dialects. It is written in a cursive variant of the Parthian chancellory script. Many Mandaean lay people do not speak this language, though some members of the Mandaean community resident in Iran and Iraq continue to speak Neo-Mandaic, a modern version of this language.
