During the late medieval period, cotton began to be imported into Northern Europe. Without any knowledge of what it came from, other than that it was a plant, noting its similarities to wool, people in the region could only imagine that cotton must be produced by plant-borne sheep. John Mandeville, writing in 1350, stated as fact the now-preposterous belief: "There grew in India a wonderful tree which bore tiny lambs on the edges of its branches. These branches were so pliable that they bent down to allow the lambs to feed when they are hungry." This aspect is retained in the name for cotton in many European languages, such as German "Baumwolle", which translates as "tree wool". By the end of the 16th century, cotton was cultivated throughout the warmer regions of Asia and the Americas.
