エンゲルベルト・ケンペル
The German scholar and physician Engelbert Kaempfer accompanied an embassy to Persia in 1683 with the intention of locating the lamb. After speaking with native inhabitants and finding no physical evidence of the lamb-plant, Kaempfer concluded it to be nothing but legend. However, he observed the custom of removing an unborn lamb from its mother’s womb in order to harvest the soft wool and believed the practice to be a possible source of the legend. He speculated further that museum specimens of the fetal wool could be mistaken for a vegetable substance.
