October 13

October 13, 1917 - Tens of thousands of people in Fatima, Portugal, witnessed what became known as the "Miracle of the Sun," a period of extraordinary solar activity that the witnesses attributed to an apparition of the Virgin Mary. Later studies would show that nothing remotely spiritual or supernatural was going on, and the extraordinary lights people saw were in fact a result of the slow burning of their own corneas as they insisted on staring at the sun.
