Tibetian medical paintings (17th century)
Created between 1687 and 1703, these paintings are pieces of educational art that interweave practical medical knowledge, depicting such things as the use of omens and dreams for making diagnoses.
As far as I understand it now, every picture depicts a certain dream that someone could have. And then they knew the meaning of this dream and give you advice or medicine that could make you feel better. I hope to find a book about it soon so I can read more.
