Focusing on a carefully curated selection of esoteric art and artefacts, this book explains the meaning and mystic power of occult ritual objects and symbols from around the world. The author identifies four key elements of occultism - mysticism, alchemy, magic and divination. Key symbols are identified and examined close up, and key rituals and practices are explained to provide new insights into the philosophies and beliefs of occultists from antiquity to today.

Occult begins with an introduction that clarifies what we mean by 'occult'. It traces the pre-Christian origins of esotericism in Hermeticism, Gnosticism and Neoplatonism, and its development as the occult sciences during the Renaissance to its rebirth in the 19th century with spiritualism, theosophy and the Hermetic Order of the Golden Dawn and the 20th-century's anthroposophy, 'New Age' and occulture movements. The book is then organized into three sections exploring Occult Foundations, Occult Philosophy and Occult Revival - each one containing three themed chapters.

For each of the nine chapters, illustrated narrative text is interspersed with double-page presentations decoding the key practices, figures and symbols relevant to that theme. From rare, ornate tarot decks to the paintings of Leonora Carrington and Ernst Fuchs, artworks and artefacts are examined in detail: the practices depicted are identified and explained and the hidden symbolism decrypted. As the book progresses, readers will not only come to understand the mysterious practices and secret ciphers of the occult but will also discover the beliefs, philosophies and rituals of occultists around the world, from their origins in the early esoteric traditions of the ancient Greeks to their reinterpretation in modern occultism.
