The word serendipity is derived from the name of the small island nation off the coast of India that is now called Sri Lanka. In the recent past it was called Ceylon, but before that it was called Serendib by the Arab sea traders. An English author named Horace Walpole, the fourth Earl of Oxford (1717-1797), wrote a charming story adapted from a Persian fairy tale called "Three Princes of Serendib". In the story, the three princes were forever happening on the most providential discoveries by pure chance. The word, if not the story, has stayed with us to this day.
