|Human beings transmit messages across the Ages. Consider the chasm between contemporary life managed by silicon chips and megalithic times when human intellect and spiritualism kept evolving, generationally, across Europe, Persia, India, China and elsewhere in Oceania as world history instructs.

All knew of the stars' nightly and annual dance, impossible for a majority of today's planetary voyagers clustered under nocturnal, incandescent canopies blighting urban sprawl.
