You may not find this terribly rewarding unless you're included here, so this is a good time for casual and random browsers to turn back before they get too caught up in the sweep and majesty of the proceedings and can't let go.
Lions have always been important symbols of power and majesty, adopted and flaunted by rulers and wannabes in paintings and ponderous speeches, on heraldic shields and emblems, and with monumental statues. And as to the statues, perhaps nowhere more insistently than in the Veneto region after Venice began expanding landward in the early 15th century.
