The term "magic" is etymologically derived from the Latin word magi, a term that was used to refer to Zoroastrians. Performances we would now recognize as conjuring have probably been practiced throughout history. The same level of ingenuity that was used to produce famous ancient deceptions such as the Trojan Horse would also have been used for entertainment, or at least for cheating in money games, since time immemorial. They were also used by various religions from times ancient, and were even known as far back as the early 17th century to be used to frighten uneducated populi. However, the profession of the illusionist gained strength only in the eighteenth century, and has enjoyed several popular vogues.
