"Be not afeard. The isle is full of noises, sounds and sweet airs that give delight and hurt not." (The Tempest)
London (CNN) -- Hundreds of millions around the world have been dazzled by the sights and sounds of director Danny Boyle's opening ceremony for the London 2012 Olympic Games.
But with the production tossing out historical and cultural references at a rapid rate, even the most ardent Anglophiles in the audience may have felt some allusions whiz over their head like an airborne nanny.
The Oscar-winning director of "Slumdog Millionaire" says the ceremony, titled "Isles of Wonder," was inspired by a passage in Shakespeare's The Tempest, believed to have been written in 1610 and set on a remote, magical island.
Although that phrase itself appears nowhere in the play, the character Caliban refers to his home as an isle "full of noises, sounds and sweet airs, that give delight and hurt not."
