I want to know the answer to the following question:
What 1350 writer stated that cotton was produced by sheep that grew on trees?
All the background I'm provided with is that "John Mandeville, writing in 1350, stated as fact the now-preposterous belief: "There grew there [India] a wonderful tree which bore tiny lambs on the endes of its branches.". Is that enough to answer the question?
Answer: yes
