What association do groups like The order of the Golden Dawn have with the tarot?
During the 19th and early 20th centuries, numerous mystical organizations such as the Order of the Golden Dawn, Order of the Silver Star, and Order of the Temple of the east, sprang up, with the avowed purpose of training people in magical and esoteric techniques as a means of creating a spiritual dynamic capable of accelerating the evolution of humanity. these groups expanded the ideas of Levi and papus, and are largely responsible for the way in which we interpret tarot cards to this day.
Two popular Tarot decks… the Thoth and the Rider-Waite–were designed by members of the Order of the Golden Dawn. This groups of mystics is also largely responsible for the astrological associations of the tarot. Although these associations can vary to some degree, most commonly the major arcana is linked with the twelve signs of the zodiac and ten planets, and each suit of the minor arcana is linked with one of the four elements.
