Foto de stock - Librarian Heike Mueller (L), Katja Conradi, from the Association Amici Bibliothecae Christianei (lit. ""Friends of the library of the Christianeum"") and dean of the school Diana Amann look through a ""Barther Bible"" at the newly renovated library at the Christianeum in Hamburg, Germany, 12 January 2017. In front of them lies a medieval copy (R-L) of Dante's ""Divine Comedy"", ""Il Filostrato"", an early work of the poet Giovanni Boccaccio, which is also set with intricate drawings, and a book of hand-written prayers of the reformator Philipp Melanchthon (1497-1560). The humanistic secondary school owns medieval writings as well as several literary rarities. Hamburg's mayor is expected for the re-opening of the new library with its 25000 books from the 14th to the 18th century. Photo: Christian Charisius/dpa | usage worldwide. - Hamburg/Hamburg/Germany
