Back in the day, the day being any time between, say, 1520 and 1600, the way to the heart of the Turkish sultans was through clockwork. Makes sense. When you have the wealth of the world at your disposal, you want the unusual and the unique. Toys, essentially, the fiddly wind-up spring machine types that whirred and turned and chimed and bonged. Fortunately for Europe, there were men who excelled in this kind of trivia.
As with anything that is not a mere commodity, the novelty value had to gear up over time. A simple one handed pocket watch becomes a bore, and so further complications – second hands, moon phases, twittery birds – have to be grafted onto the basic work. By the turn of the seventeenth century, it would take something very complicated indeed to turn the head of a jaded potentate. And as at that time, Britain, not yet fully engaged with its eventual empire, was still wooing the sultans in hopes of profitable trade arrangements for the Levant Company, the gift had to be spectacular indeed.
