The Buddha of MedicineYuan dynasty (1278-1364), ca 1319
Water-based pigment over foundation of clay mixed with straw

Bhaiṣajyaguru is typically depicted seated, wearing the three robes
of a Buddhist monk, holding a lapis-colored jar of medicine nectar
in his left hand and the right hand resting on his right knee,
holding the stem of the Aruna fruit or Myrobalan between thumb and
forefinger. In the sutra, he is also described by his aura of
lapis lazuli-colored light. He is also depicted standing on a
Northern Wei stele from approximately 500 AD now housed in the
Metropolitan Museum of Art, accompanied by his two attendants,
Suryaprabha and Candraprabha. Within the halo are depicted the
Seven Bhaiṣajyaguru Buddhas and seven apsaras.
