When some think of Persian literature, their minds might immediately turn to the Rubaiyat of Omar Khayyam. There's much more than that, of course, and this online exhibition from the Library of Congress explores over a millennium of Persian printed works. Designed to complement an in situ exhibit, the sections here include The Persian Language, Writing Systems and Scripts, Religion, and Science and Technology. Each section contains a narrative essay, along with examples of illuminated manuscripts and other relevant pieces of historical ephemera. First-time visitors shouldn't miss The Epic of Shahnameh area. Here, they can learn about this epic poem that recounts the history of pre-Islamic Persia or Iransahr (Greater Iran). All told, it contains 990 chapters with 50,000 rhyming couplets.
