With a large beard upon his face, a black blanket he does embrace.

This couplet poses a classic riddle. It describes an object with a prominent opening or 'mouth,' which could also imply a large, perhaps bearded, front. The second line adds to the imagery, stating that this object is covered with a black blanket. This hints at something dark, possibly hidden, or simply an object with a dark covering. It's designed to make you ponder the everyday things around you.
