Wouldst thou their death? I’ll write a potent spell
Upon an ass’s thigh-bone, hide it well
Beneath the threshold where they dwell.
Wouldst thou their madness? I will tie their mind
To some low creature of a restless kind,
A bird or fish, that when it moves they rage,
And when it rests their fury they assuage;
And none shall know the secret saving I,
So that for lack of remedy they die.
Abu Sumûm the wily one I am,
