That little heart of red bricks in the sky of the vault is the most famous promise of love in Venice: tradition holds that two lovers who touch it together will stay together for ever, and that anyone alone can make a wish for love — destined to come true within the year. Behind those few bricks is the legend of Orio and Melusina, the most heart-rending love story of the Bragora. Orio was a young fisherman who cast his nets towards Malamocco.
