The first scholar outside Persia to study Omar Khayyam was the English orientalist, Thomas Hyde (1636-1703). In his Historia religionis veterum Persarum eorumque magorum (1700), he not only devoted some space to the life and works of Khayyam, but also translated one quatrain (robāʿi) into Latin. The first quatrain in English was published in 1816 by Henry George Keene (1781-1864) in the famous magazine Fundgruben des Orients/Mines d’Orient. Although the founder of the Fundgruben, Joseph von Hammer-Purgstall (1774-1856), translated a few of Khayyam’s poems into German in 1818, and Sir Gore Ouseley (1770-1844) into English in 1846, Khayyam was to remain relatively unknown for some time
