Creator's Description: This article provides a translation and study of a recently discovered ceremonial staff housed at the Metropolitan Museum of Art. Based on the identification of two names found in the inscription, Sodnam Ombu Taiji (1587-1625) and the Fourth Dalai Lama (yon tan rgya mtsho, 1589-1617), it situates the piece in the historical context of early seventeenth-century Mongol-Tibetan relations.
