This image was taken from a 15th century Tibetan painting that depicts, according to scholarly opinion, one of the Four Mortal Buddhas, either Kasyapa or Dipamkara.  These persons attained Buddhahood thousands of years before Gautama Buddha, the Buddha of our era.   Like Gautama Buddha, this Buddha is attired in modest dress without the elaborate jewelry of the other Buddhas.  The right hand of this red Buddha is in the wish-granting gesture (varada mudra).  He is flanked by two arhats.  He is seated on a cushion resting on a lotus of multi-colored petals, and which itself rests on a lion throne.
