Princess Diana was named after another Lady Diana Spencer from the eighteenth century.
There was one more Lady Di from the eighteenth century who had a similar destiny and was also supposed to marry the Prince of Wales. Instead, she was married off to Lord John Russell, who later became the fourth Duke of Bedford. This Lady Diana was “a mirror-image” of the life lived by the most recent holder of the title, and she died at the age of 25.
ARTHUR: The Lady of the Lake,...
...her arm clad in the purest shimmering samite, held aloft Excalibur from the bosom of the water signifying by Divine Providence that I, Arthur, was to carry Excalibur. And that is why I am your King.
DENNIS: Listen. Strange women lying in ponds distributing swords is no basis for a system of government. Supreme executive power derives from a mandate from the masses, not from some farcical aquatic ceremony.
ARTHUR: Be quiet!
DENNIS: Well, but you can't expect to wield supreme executive power just 'cause some watery tart threw a sword at you!
ARTHUR: Shut up!
DENNIS: I mean, if I went 'round saying I was an emperor just because some moistened bint had lobbed a scimitar at me, they'd put me away!
Got to watch the film again this evening...
