A war that would last for a century convulsed much of western Europe. Divisions between Orthodox and Roman Catholic Christianities endured, and in 1378 the West divided again between popes of Avignon and Rome. Arabic literary cultures linked Fes and Granada to Jerusalem and Damascus; Persian and Turkish writings began to flourish south and west of Constantinople; Jewish intellectuals treasured Arabic texts as well as Hebrew writings; Armenian colophons proved unique. From 1414-18 western nations gathered to heal their papal schism while also exchanging literary, humanist, and musical ideas; visitors from the East hoped for commitment to wider European peace. Freed from nation state historiography, as bequeathed by the nineteenth century, these 82 chapters freshly assess the free movement of European literature in all its variety, local peculiarity, and regenerative power.
