Divination – a controversial concept. In the age of Classic Greece divination was seen as crucial for the proper governance of Athens for example. The Delphi Oracles used a combination of intoxicating herbs and even volcanic fumes, and the entire group were all female.
Greek divination is the divination practiced by ancient Greek culture as it is known from ancient Greek literature, supplemented by epigraphic and pictorial evidence. Divination is a traditional set of methods of consulting divinity to obtain prophecies (theopropia) about specific circumstances defined beforehand. As it is a form of compelling divinity to reveal its will by the application of method, it is, and has been since classical times, considered a type of magic. Cicero condemns it as superstition.
Tarot ogrinated as the set of playing cards we know today. Over time the game added more and more “extra cards” that then became over time the tarot we know today. There are three notable decks. The deck created by Arthur Waite in the late 1800s is a nice, modern deck that is based upon the traditional fortune telling cards but everything also has a basis on Kaballah, of which Waite was an expert in his time. Later Aleister Crowley developed the Thoth Tarot Deck, which has a couple of modifications to meet his concept of the turning of Aeons, but is based upon a unique concept of Kabbalah combined with the power of modern art.
Prior to the 17th century, tarot cards were solely used for playing games and the Fool and 21 trumps had simple allegorical or esoteric meaning, mostly originating in elite ideology in the Italian courts of the 15th century when it was invented.[2] The occult significance began to emerge in the 18th century, when Antoine Court de Gébelin, a Swiss clergyman and Freemason, published two essays on Tarot in his Le Monde Primitif (The Primeval World),[3] a never-completed encyclopedia. In the first essay, “Du Jeu des Tarots” (The Game of Tarots), Court de Gébelin assigned Egyptian, kabbalistic, and divine significance to the tarot trumps.
Tarot as a system that is much younger than ancient greece or even the IFA of the Yoruba which is similar to the IChing from China in the concepts it deals with, however if you live in modern, corporate society, Tarot is useful because of the special way it maps authority and hiearchy into the picture.
