Medi Teranus: My Claim to Fame

I have to do this, establish my signature. My claim is and was that there exists a location on earth, medi teranus, foundational in the logic of empirical science, where, over seven cycles of twenty-four hours the measure of darkness complements the measure of light less ness. It is called the loch ness mistress. I have actually been to a place similar in proximity. I danced at the foot of a rainbow, once, where all I saw was other rainbows of seven colors each. The question concerns why seven. Why seven colors? Why seven days? Twelve we take for granted.
