(( In blogcanon or out of it? In blogcanon I doubt it. Out of canon, I figured the Apple of Discord story is well-known enough to have lent some inspiration to the imagery; an item that causes jealousy, covetousness, and strife. However, Golden Apples show up in various other myths and fairytales and poems and such. ))

I will find out where she has gone

And kiss her lips and take her hands;

And walk among the dappled grass,

And pluck till time and times are done

The silver apples of the moon, 

The golden apples of the sun.

- William Butler Yeats, excerpt from The Song of the Wandering Aengus
