I believe that the instrument Shakira brought back into the mainstream with her hit Whenever, Wherever are the panpipes.
That instrument is a type of a flute consisting of numerous pipes which produce sound when blown into. The name comes from Greek mythology, where the Greek god Pan is often depicted using that instrument. Other than the panpipes, she also used the charango, which is a type of a lute.
Capitals - Paired columns which usually have a square top and round base. These usually depict biblical scenes or legends of local saints.
Latin cross - most churches or abbeys would follow the shape of a Latin cross. The Latin cross is a universal symbol of Christianity.
Piers - columns were replaced with piers which were often used to provide support to arches. the piers are usually cruciform (cross-like) in shape when they intersect two big arches.
I believe it is a positive shape, but I could be wrong
