Faith, hope and love
When we visited Vienna this installation was displayed in Stephansdom.
(Click on image for larger version.)
Glaube (faith) and Hoffnung (hope) are visible; Liebe (love) is at the far end. The whole piece is called Collective Heart by Eva Petric. I think it adds light and life to the cathedral. The ‘umbrellas’ are made from pieces of crochet-work. This gives a sense of being delicate, but not fragile.
