Cultus Arborum - Anonymous - Cultus Arborum: A Descriptive Account of Phallic Tree Worship was published anonymously in 1890, although the author was most probably Hargrave Jennings, a British Freemason, Rosicrucian, author on occultism and esotericism, and amateur student of comparative religion. The book explores the origins and practise of phallic tree worship and covers subjects such as the ceremonies connected with tree worship, invocations and rituals, tree worship in different parts of the world, such as Persia, Iceland, and Egypt, Irish superstitions, the different types of trees used in worship, sacred trees in the Old Testament, and more.
