A myth started me looking up pomegranates.
In Granada, Spain, last fall, the guides explained that Granada was named for pomegranates, granada
in Spanish, and that the Moors had brought pomegranates to Spain. Which I heard as "the Moors brought pomegranates to Europe" since they introduced many Middle Eastern and Asian plants to Europe by planting them in Spain.
But I knew that pomegranates played an important role in Greek mythology...so the Moors couldn't have brought pomegranates to Europe.
Pomegranates appear in mythology all over the Old World. Bright red flowers, big fruit full of seeds--everyone noticed them.
