Yes, August 12 marks the death of Cleopatra VII Philopater, the last ruler of what we now think of as ancient Egypt. In 30 BC, the last of the Ptolemies breathed her last; whether or not an asp was truly involved is dubious, but it makes for a great tale.
Theda Bara's Cleopatra is lost; Claudette Colbert's is an Art Deco fever-dream; Elizabeth Taylor's is a hot mess. By contrast, Lady Olivier does her best to leaven cinematic excess with a measure of Shavian, if not quite Shakespearean, grace, and her costumes, the occasional howler aside, actually look more than a shade pharaonic.
The actual Cleo was a Macedonian Greek who by all accounts was a little more generous on the nose side than any of her screen impersonators (possibly excepting Miss Bara); still she must have had something Leigh-ische to entrance two of the most powerful men of her time. It didn't quite work out as she hoped, but 20 centuries later we're still talking about her, no?
