den neuen » der neuen, die neuen
2 orbis » 2 orbits, 2 orbit, 1 orbis

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: (( novum testamentum 2 orbis antiquus / studien zur umwelt ((den nieuwen) OR (de nieuwe)) testament ) OR ( novum ((testamentum ex) OR (testamentum _)) urbis antiquae / studien zur umwelt ((die neue) OR (den neuen)) testaments )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( novum testamentum 2 orbis antiquus / studien zur umwelt ((den nieuwen) OR (de nieuwe)) testament ) or ( novum ((testamentum ex) or (testamentum _)) urbis antiquae / studien zur umwelt ((die neue) or (den neuen)) testaments ))".
• Adding a wildcard symbol may retrieve word variants: (( novum testamentum 2 orbis antiquus / studien zur umwelt ((den nieuwen) OR (de nieuwe)) testament ) or ( novum ((testamentum ex) or (testamentum _)) urbis antiquae / studien zur umwelt ((die neue) or (den neuen)) testaments ))*.
