The double-headed
eagle is the emblem of the thirty second and thirty-third (and highest)
degrees of Scottish Rite Freemasonry. There exist a multitude explanations of
the meaning of the two-headed eagle, from the mundane (it's a heraldic device)
to the fantastic (it's the devil, I tell you!). In fact, the eagle is a symbol
of the theurgic process undertaken by the masonic initiate- a symbol of a completed
alchemical process.
In the Hermetic
Alchemical doctrine on which many Masonic symbols are based, the eagle is a
sign of Scorpio, and is emblematic of transformation- the lowly, crawling scorpion
remade into the soaring creature of air. Alchemically, the eagle was a symbol
of purified sulfur, and was used in alchemical images to portray the ascending
spirit. The double heads are often emblematic of the reconciliation of matter
and spirit. Other elements in the Masonic eagle reinforce the alchemical symbolism-
a sword representing heavenly fire, and the crown of spiritual attainment.
The Masonic eagle
is often referred to as the "Eagle of Lagash," after one of the oldest
uses of the emblem, in the ancient Sumerian city of Lagash. The two faced eagle
was popularized in Europe by the Emperor Charlemagne, and the symbol was adopted
formally into Freemasonry in the mid-eighteenth century, by the Council
of Emperors of the East and West. At that time, the device was commonly
used to depict the uniting of two bodies into one; this was probably a factor
in the decision to use the eagle symbol.
