August 12, 30 BCE — Cleopatra commits suicide

Cleopatra VII, reputedly one of the most beautiful women ever to have lived, was the eleventh and last Ptolemy ruler of Egypt. A cunning politician who had co-ruled with her brothers Ptolemy XIII and XIV until the friction grew to the point where she was deposed and exiled.

She returned to Egypt and reclaimed the throne with the aid of Julius Caesar, with whom she had a son. After the death of Caesar, she manipulated his successors, Octavian and Marc Antony. When the tensions between the two Romans erupted into civil war, she threw in with Antony – who lost the war. Finally, in August 30 BCE, as Octavian invaded Egypt and Antony’s troops defected to the winning side, she and Antony each committed suicide – legend has it that Cleopatra provoked an asp (a poisonous snake native to Egypt) into fatally biting her.

August 12, 1958 – “White Wilderness” premieres

The legendary documentary that began the whole “lemmings commit suicide” myth, White Wilderness was 72 minutes of the Disney Corporation making nature more interesting (for a given value of ‘interesting’) in another ‘True Life Adventure’. The scene of the lemmings jumping into the ocean has been at the centre of a number of controversies over the years – it’s actually a river, not the ocean; the filmakers built an apparatus to push the lemmings along; and, of course, lemmings are no more suicidal than any other species.

To be fair, at no point does the narration state that the lemmings are deliberately committing suicide, but nonetheless, this is the starting point of that urban legend.
