Analysis of Witchcraft By A Picture

I fix mine eye on thine, and there
Pity my picture burning in thine eye;
My picture drowned in a transparent tear,
When I look lower I espy.
Hadst thou the wicked skill
By pictures made and mard, to kill,
How many ways mightst thou perform thy will?

But now I have drunk thy sweet salt tears,
And though thou pour more I'll depart;
My picture vanished, vanish fears
That I can be endamaged by that art;
Though thou retain of me
One picture more, yet that will be,
Being in thine own heart, from all malice free.
