Let the Union of the Red Lion and the White Eagle be neither in cold nor in heat.
From The Chariot of Antimony by Basil Valentine (1642)
The Great Alchemical Work
Let the Lion and Eagle duly prepare themselves as Prince and Princess of Alchemy - as they may be inspired.
Let the Union of the Red Lion and the White Eagle be neither in cold nor in heat. Let their working be sublimated.
Now then comes the time when the elixir is placed in the alembic retort to be subjected to the gentle warmth of
the menstruum. The wise alchemist knows the required time in the alembic retort for the transmutation - the
medicine of metals, the royal antimony, the quintessence. If the "Great Work" be transubstantiation then the Red
Lion may feed upon the flesh and blood of the God, and also let the Red Lion duly feed the White Eagle - yea,
may the Mother Eagle give sustain-molt and guard the inner life.
It is testified that, in special operations desired by the Lion and the Eagle, there is unfailing great virtue and force in employing the Anointing Ritual, be it on a letter, a talisman, a magick sigil, a special object of desire, a symbol of aspiration, or upon living flesh
