Rasselas, Prince of Abyssinia, leaves the easy life of the Happy Valley, accompanied by his sister Nekayah, her attendant Pekuah, and the much-travelled philosopher Imlac.

Johnson''s tale is not only a satire on optimism, but also an expression of truth about the human mind and its infinite capacity for hope.
