The Heart of the Matter
Embedded into the floor of the sanctuary, a few paces from the Pala d' Oro, there is a heart-shaped slab of porphyry. This marks the spot where Erizzo's vital organ is buried. The porphyry heart is inlaid with two smaller images. One is easily recognisable as the Corno Dogale, the special hat which doges wore, while the black shape is supposed to represent a hedgehog (riccio), symbol of the Erizzo family.
The rest of Erizzo's body is buried in the church of San Martino, which lies opposite what was once his family palazzo.
