Overview
The Hanged Man (XII) is the twelfth Major Arcana card in most traditional tarot decks. It is used in game playing as well as in divination.
It depicts a pittura infamante, an image of a man being hanged upside-down by one ankle (the only exception being the Tarocco Siciliano, which depicts the man hanged by the neck instead). This method of hanging was a common punishment at the time for traitors in Italy. However, the solemn expression on his face traditionally suggests that he is there by his own accord, and the card is meant to represent self-sacrifice more so than it does corporal punishment or criminality.
In other interpretations, The Hanged Man is a depiction of the Norse god Odin, who suspended himself from a tree in order to gain knowledge. There is also a Christian interpretation that portrays Judas Iscariot, and include the bags of silver in his hands. In the Lo Scarabeo African American tarot deck the 12th card of the major arcana is the Observer, depicting the Nigerian god "Ifa" of fate and destiny blindfolded and surrounded by eyes.
Description
A 1393 decree for Milan and Lombardy of the punishment for traitors: "Let him be drug [dragged] on a [wooden] plank at a horse’s tail to the place of execution, and there be suspended by one foot to the gallows, and be left there until he is dead. As long as he lives let him be given food and drink."
