A brief one here: a demon from Herrick that takes the form of a pagan god. It aids people who want to harm themselves by destroying their own capacity for love. Love, in medieval theology, being one of the forms of God, and that humans should love being one of the commands of God, this is a sort of damnation. On reading critics of Herrick there’s a statement that this really is Cupid and that the cup is a trick of the real Cupid to punish the poet for forsaking the cause of love. and that he will love regardless. I prefer my interpretation for Ars Magica purposes, but suit yourself. Stats for the impish version eventually.
***
A crystal vial Cupid brought,
Which had a juice in it:
Of which who drank, he said, no thought
Of Love he should admit. I, greedy of the prize, did drink,
And emptied soon the glass;
Which burnt me so, that I do think
The fire of hell it was.
Give me my earthen cups again,
The crystal I contemn,
Which, though enchased with pearls, contain
A deadly draught in them.
And thou, O Cupid! come not to
My threshold,—since I see,
For all I have, or else can do,
Thou still wilt cozen me.
