The Lion of St. Mark has been a symbol of Venice and the surrounding area going back to at least 1261, possibly earlier. The legend goes that St. Mark was shipwrecked in the Venetian lagoons when an angel in the form of a winged lion appeared and proclaimed “Pax tibi Marce, evangelista meus. Hic requiescet corpus tuum.” (Peace to you, Mark, my evangelist. Your body will rest here.) Later authorities claimed the lion was a symbol of majesty, the book stood for wisdom, and the halo for piety, but this sounds very much like the sort of post hoc rationalization that was common in later centuries.

Both coats quartered here were used by the de Bermingham family at various points in time. The family also quartered the coats, but in opposite quarters; the city changed the order for difference. The city was previously granted arms in 1889, which used a fess ermine instead of a cross, and a mural crown instead of a mitre. The supporters in the previous arms were also reversed, with Industry on the dexter and Art on the sinister.
