Why does the general public cling to uninformed ideas? I honestly wish I knew why humans are so mired in misconceptions.
Perhaps Graham Hancock's summary statement best meets the test of Occam's Razor: “We [humans] are a species with amnesia….”
And this pattern traces back (at least) to 238 BCE, when Egypt’s ‘traditional’ calendar year had strayed greatly off-course in slow motion. That was a key reason why Ptolemy III erected the first multilingual stone stele to transmit public announcements. (Recall that he was grandfather to Ptolemy V of Rosetta Stone fame.)
One-thirteenth of the lines chiseled into Potolemy III’s stele contained a key priestly order in the midst of other messages. The order decreed a reset of the 365-day Egyptian calendar by adding one ‘leap’ day every fourth year.
But even though Egypt's calendar had strayed greatly off course --for example, with farmers planting crops at unfruitful times-- the stele information was ignored. Instead, the Egyptian general public persisted in adhering to their pre-exsting beliefs. And annual time-keeping errors persisted in ongoing fashion.
Augustus, as the first Roman Emperor over Egypt, later enacted the needed reform about 25 years before Jesus of Nazareth. The Emperor simply declared that all would observe an annual solar cycle of 365+¼ days. This was in keeping with Rome’s, astrologer-derived Julian Calendar. And since Rome ruled by force rather than royal charisma, Egyptians did adhere to the Augustine decree.
