The Vegetable Lamb of Tartary

Likely the definitive source of information on the Barometz, aka the Vegetable Lamb of Tartary. The first half of the book dives into the origins of the legend, along with possible explanations for it and various mentions of it throughout history.

The second half of the book covers the history of cotton - the origin of the myth - and I found it to be less relevant to the research I'm doing, so I wasn't as interested.

There is also a detailed Appendix containing quotes, sources, and brief biographies.
