As previously referred to, the Cathedral Santa Maria is known as The House of Light or the Pulchra Leonina. Remarkably, when we got inside, it was pretty dark, except for a dramatic shaft of blinding sunlight coming down from the ceiling, which I found fantastic but nobody else took any notice of. TG accidentally walked under it and she was drawn to look upwards, as if for divine inspiration. I observed this and realising the significance and drama of the moment, I said "Hold it there!" and I captured the image with my trusty Samsung. In truth, the contrast, i.e. the degree of light and dark, is exaggerated by the camera setting, but maybe, just maybe, that was exactly how it was meant to be and the House of Light truly has lived up to its name! In fact, at the risk of disappointing some, I can say that this moment was, most definitely, always going to happen from the beginning of time some 13.8 billion years ago (if, that is, one accepts the philosophical notion of determinism, which, it has to be said, is the compelling conclusion to the scientific concept of cause and effect). Admittedly there are those who do challenge the objective reality of determinism by pointing out that some sub atomic activities appear random (Heisenberg's uncertainty principle is one example of this, alongside the varying rate at which atomic radioactive decay can occur). However my own answer to this conundrum is to point out that there are no examples of something happening one way and then happening a different way via some mysterious re-running of time (which is self-evidently impossible, anyway). Put even more simply, we know we cannot change the past, but equally, a less frequently noted truth is that we cannot change the future either. If any reader thinks we CAN change the future then answer this question: what would you change the future from and to? - there can be and is only ONE past and there can be and is only ONE future. Notice, incidentally, that I refer to the future in the present tense, since it's existence in its exact form is entirely inevitable. Finally, I did query whether TG had experienced any divine inspiration, and the answer was that she felt urged by some mysterious force to go for lunch in the old town square and order mixto frito and chipirones (which is what we did).
