Hungarians still seek “Raven King's” library

Hungarians are still searching for their own "Holy Grail," the lost library of Matthias Corvinus, a 15th century king who assembled more than 50,000 hand-copied volumes of religious texts, war stories and biographies, only to have them stolen by raiding Turks.

Only 216 of the books are known to still exist, but scholars never give up hope that the library will yet be discovered.
