Epona,
Bigby was an Archmage who exists in PnP AD&D. There is a whole series of "Bigby's ????? Hand" spells. One is something like "Bigby's grasping Hand"...it's a spell that will create an illusory hand that will grab an opponent and do whatever you want to them. There is also one like, "Bigby's forceful hand" that will form a hand that pushes whatever you want with a huge amount of space. They are generally pretty cool spells, IIRC.
Been a long time since I played PnP...
