Perhaps you should try some spelling variations:
de litterature » la litterature, et litterature
de literature » de lite'rature, de literatura, e literature
1 letteratura » e letteratura, _ letteratura, di letteratura
grani libro » gran libro
agenda ii » agenda iii, agenda i, agenda iv
dei grani » dei grandi, dei gratia
ii 1 » ii _, ii a, i 1

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( _ agenda ii 1 letteratura e ) OR ( dei grani libro ((de literature) OR (de litterature)) arte ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( _ agenda ii 1 letteratura e ) or ( dei grani libro ((de literature) OR (de litterature)) arte ))*".
