Perhaps you should try some spelling variations:
"artes mechanicae" » "art mechanical", "parts mechanical", "sites mechanical"
"artes magicae" » "artis medicae"
"artis logicae" » "artis logical", "artis logica", "artis logische"

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: (((("artes magicae") OR ("artes mechanicae"))) OR ("artis logicae")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"artes magicae\") OR (\"artes mechanicae\"))) or (\"artis logicae\"))".
• Removing quotes may allow a broader search: (((( artes magicae ) OR ( artes mechanicae ))) or ( artis logicae )).
• Adding a wildcard symbol may retrieve word variants: (((("artes magicae") OR ("artes mechanicae"))) or ("artis logicae"))*.
