I know this is a common image. One you may see many times over.
To me this is a comfort image. A copy of this picture in a cheapy plastic frame (the kind that yellows with age) hung in my bedroom as a child. This is what I saw every day when I opened my eyes, every night before I fell asleep and all the in betweens.
Sometimes as an adult, when I feel stressed out, I close my eyes tight and bring that image up to the front of my mind like a slide show of zillions of things my brain has processed.
That is comfort to me.
