Perhaps you should try some spelling variations:
convegni della » convegno della
convegno del » convegno della, convegno di, convegno per
succincte de » succinct de, succinct _, succinate _
succinto la » succinto della, succinto dell
succinto e » succinte de, succinto dell
zuccari » zaccaria

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: i ((convegni della) OR (convegno del)) sala zuccari / ((succinto la) OR (((succinto e) OR (succincte de)))) republica.
• The words AND, OR and NOT may confuse the search; try adding quotes: "i ((convegni della) OR (convegno del)) sala zuccari / ((succinto la) or (((succinto e) or (succincte de)))) republica".
• Adding a wildcard symbol may retrieve word variants: i ((convegni della) OR (convegno del)) sala zuccari / ((succinto la) or (((succinto e) or (succincte de)))) republica*.
