La cultura medieval islámica ha dado figuras espléndidas. Omar Jayyam, poeta y filósofo, algebrista y astrónomo, es sin duda la más fascinante de todas. Su pensamiento fue heterodoxo, su saber inmenso, su obra variadísima. De lo que nos ha llegado de su poesía no siempre es fácil distinguir lo auténtico de lo apócrifo, y de lo que sabemos de su vida, la historia de la leyenda.
