For more on labyrinths, this website is full of information.
Below is a poem-like thing with some of my favorite pictures of labyrinths I have known and loved:
We have walked labyrinths
made of fabric, made in fields,
laid out in tiles
or offered by cathedrals.
We have relied
on the promises of the labyrinth:
one path in, no dead ends,
no false turns, not a maze.
We have trusted
that the path leads
to a center that can hold
us all in all our complexities.
