French-born artist Edmund Dulac (1882-1953) achieved prominence during the Golden Age of Illustration. His work encompasses a wide variety of themes and styles, although he preferred to work in watercolors and remains best known for his imaginative illustrations for fairy tales and other children's books. Omar Khayyam (1048-1131) was among the Middle Ages' most influential thinkers. Scholar, astronomer, mathematician, and poet, the Persian philosopher wrote one of the most important pre-modern treatises on algebra but is best remembered for his poetry. Edward FitzGerald (1809-1883) was a scion of one of Great Britain's wealthiest families who devoted himself to Oriental studies. His translation of Khayyam's verse, published anonymously in 1859, initially received little attention but gradually achieved enormous popularity and influence.
