This
square jade seal bears a crouching mythical beast and was made for the
Yuan Dynasty guoshi (National Preceptor). Its inscription is
written in Phagpa script. After Phagpa was named National Preceptor,
these titles became more and more honorific. The title guoshi
became Guanding guoshi (Empowered as National Preceptor), and
was later changed to Da Yuan guoshi (National Preceptor of the
Great Yuan).
