Holly is a religious symbol in many parts of the world. Ancient Romans associated it with their sun god, Saturn, whilst Celtic lore believe it represents the eighth month of the Tree Calendar.
In Celtic mythology, the Holly King ruled from summer to winter solstice, representing the darker half of the year. Ancient Celts decorated their homes with the brightness of holly berries, believing it to be a symbol of luck. Others believe holly leaves to represent the thorns of Jesus's crown and the berries to represent his blood. In Scandinavia, holly is called Christ's Thorn. Ancient druids considered this a sacred tree of witchcraft.
