Throughout the season runs evidence of a very rich Christmas ethnobotany, with ancient traces we will follow to their roots in this book. During this excursion into the past, we will learn much about Christmas trees and Christmas greens; about Christmas spices, scents, and incense; about protective rituals that have survived until modern times. The mythology of plants leads us to the origins of the culture of shamanism and the sacred botany (hierobotany) of ancient times—into medieval customs involving witches’ magic, the warding off of demons, fertility rites, and rites of sacrifice.
