The History of Rasselas, Prince of Abyssinia
Prince Rasselas lives in a secluded, utopian valley. Every desire, every whim of the inhabitants of the valley, everything they could possibly want is supplied.
However, Rasselas begins to realize that though every care is taken to provide for his pleasure, he is not happy.
He eventually escapes the Happy Valley, along with his sister, Princess Nekayah and aritsan/inventor, Imlac. They travel to Egypt in order to observe how people truly live outside the valley, and to search for they key to happiness.
This was an excellent fable! It speaks to some universal truths and the human condition. Even though it was written in the Eighteenth Century, it is absolutely timeless. I loved it!
