The Erinyes are also known as Daemons of Vengeance. The following excerpt is taken from Daemonic Summoning for Dummies, vol 23:

Should ye wish for some revenge
Get thy butt to to an evil henge
Bring thy target’s hair and blood
And a finger or two would be pretty good
Set them afire and say this spell
But be careful not to burn thyself
“I call the Erinyes, I brought you some stuff,
their owner’s a jerk, and I’ve had enough.
So crack out thy whip, and crack out thy tail,
and slash them and lash them while I grab an ale.”

At the time of writing this, we couldn’t get the incantation to work, but the author of Daemonic Summoning for Dummies, the Tauros Warlock, Alistair Cowley, assures us that 10% of the time it works all the time.

We suspect the Devil really is in the details.
