Samuel Liddell (or Liddel) MacGregor Mathers (8 or 11 January 1854 – 5 or 20 November 1918), born Samuel Liddell Mathers, was one of the most influential figures in modern Occultism. He is primarily known as one of the founders of the Hermetic Order of the Golden Dawn, a ceremonial magic order of which offshoots still exist today. Mathers was an eccentric, adding the "MacGregor" surname as a claim to Highland Scottish heritage, although there is little evidence of such in his family background. He was a practicing vegetarian, or (according to some accounts) vegan, an outspoken anti-vivisectionist, and a non-smoker. It is known that his main interests were magic and the theory of war, his first book being a translation of a French military manual.
The Tarot is a short essay published by Mathers in the late 19th century. This edition is specially formatted with a Table of Contents and images of Mathers and various tarot spreads.
