Original: The colophons attest to the existence of the Mandaeans during the late Arsacid period at the very latest , a fact corroborated by the HarrÄ n GÄ wetÄ legend , according to which the Mandaeans left Judea after the destruction of Jerusalem in the 1st c. AD , and settled within the Arsacid empire .
Simplified: A legend called HarrÄ n GÄ wetÄ also strengthens this . According to this legend , the Mandaeans left Palestine after the destruction of Jerusalem in the 1st century AD and settled inside the Arsacid empire .
