Which begs the question, "what is the relative price today?" Well, according to Google, a live sheep can be had for around $450, and a 1.5 oz container of ground ginger is about $4, so a pound would be around $42, meaning you could get about 10 pounds of ginger today for the price of that sheep.

Thanks for taking the time to compile your periodic table and describe all the spices within. It is very helpful.
