The crucified serpent represents the reign of the astral light that gives life to the universe and permits the alchemist and mage to recreate life. The serpent is also drawn in such a manner so as to allude to the Hebrew letter Aleph, the symbol of the beginning of all things.
Oh and the caduceus (or cadeceus I don't know how it's spelled right) is a related symbol, whose two serpents can symbolize the two of the three main elements of alchemy (Sulphur/Soul and Mercury/Spirit). If we take the two serpents and the orb at the top of the staff, it can also be interpreted as the three stages of the alchemical process.
By the way, is there any topic dealic with alchemical refferences and symbols in FMA around here? I only found a closed thread...
