determines Wotan to secure the gold at any price, and he bids
Loge lead the way to Alberich's realm, following him bravely
down through a deep cleft in the rock, whence rises a dense mist,
which soon blots the whole scene from view.

In the mean while, the dwarf Alberich has conveyed the gleaming
Rhinegold to his underground dwelling, where, mindful of the
