Before I carry on I want to address the gold thing.
Sure there maybe some limited truth, that eating gold gives extended life but I think gold is more symbolic of God or the Sun.
Even in the Bible, God is still described as being like the Sun, the Bible is full of Pagan symbolism and much of it helps you to understand the true meaning.
Here is two examples of God being shown as the Sun, in the Bible. Revelations 1:16
And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strength.
That's exactly what the pagans did, worshiped their gods as the Sun and used the Sun as a symbol for them. The Sun = strength and something that gives life = God.
Second verse ...Revelations 12:1
And there appeared a great wonder in heaven; a woman clothed with the sun,
and the moon under her feet, and upon her head a crown of twelve stars:
Now this means literally that God is her clothing but I will get to that in a minute.
As to the moon part, the three stages of the moon, represent the goddess or women, new moon = young women, mother = full moon and old moon = crone or old lady. The moon at her feet, means she is no only waxing and waning like the moon.
