Zelda: Twilight Princess Easter Egg - Biggoron Sword from OOT in TP

While traveling through the last dungeon, examine the niches in the wall. (I was speed running, so no map or compass.) In one, you find the original Biggoron's Sword from OOT, slightly updated but big and beautiful as ever! (Must use the lantern to locate. I think it was in room that looks like a Greek female sign, in the hall to the right of the chest in the room.)
