Gulistan (Persian: گُلِستان, romanized: Golestān, lit. 'The Flower Garden'), sometimes spelled Golestan, is a landmark of Persian literature, perhaps its single most influential work of prose. Written in 1258 CE, it is one of two major works of the Persian poet Sa'di, considered one of the greatest medieval Persian poets. It is also one of his most popular books, and has proved deeply influential in the West as well as the East.The Golestan is a collection of poems and stories, just as a flower-garden is a collection of flowers. It is widely quoted as a source of wisdom.
