I'm glad you wrote parable, and not parabola,
although I didn't notice that at first reading,
causing me to feel the wet-blanket responsibility
to point out that a rainbow would be a complete
circle around the axis of the viewer and the sun
behind him, were it not interrupted by the earth.

Yours truly,
