The winged lion of St. Mark guards the tourists of Venice. The eyes of the beast are cast upwards towards the heavens whilst the passage in his book reads "Pax tibi Marce, evangelista meus. Hic requiescet corpus tuum." (May Peace be with you, Mark, my evangelist. Here your body will rest.)
This tradition was used as justification by Rustico da Torcello and Bon da Malamocco in 828 for stealing the remains of St. Mark from his grave in Alexandria and moving them to Venice, where they were eventually interred in the Basilica of St. Mark.
