sundays

sunday has its own character, unique among the other days. if a man were to fall asleep for a year or a decade, and if he awoke, bearded and bedraggled, on a monday, he'd think nothing of it. but if he happened to wake on a sunday, surely his first thoughts upon recollecting his senses would be the confirmation, by sight and feeling, that it was the holy day, and not mourn the time lost but rejoice in the special sunlight and otherwordly choir of the sabbath.
i do not know if it is a human thing or a natural thing, whether man just decided upon the 7th day to consecrate, or if something about the angle and quality and consistency of the light just made the 7th day something inherently special. to put it another way: was a sunday chosen by man for the diffuse and perfectly angular solar glow? or did the atmosphere of the day change its character to meet the demands of the pious mass? which came first, or which was subsequently changed as a result?
