> On merchants who netted ginger, cinnamon and rhubarb from the Nile. In medieval price lists, a pound of ginger sold for the price of a sheep; a pound of saffron, the price of a horse.

A modern horse costs $3000 - $8000. Saffron at the grocery store costs $5 - $20 per gram, but you can get it for wholesale at $1000 - $5000 per pound.

So saffron is about the same affordability now, even though it's more common.
