Who is Woman in Prison from The Weight of Glory and Other Addresses and what is their importance?

The "Woman in Prison" is a fable about a woman who gives birth to a son in a hole of a prison, with only a glimpse of sunlight to prove the existence of the outside world, a story that also illustrates man's struggles to understand heaven. The woman draws pencil drawings of the outside world for her son, but when she tells him that the pencil lines do not exist sin nature, he is unable to comprehend the reality of the landscapes. In this way, artists attempt to represent the actual world, but must rely on lesser mediums to represent the actual reality.
