the dove is a harmless and pleasant creature, with no bitterness of gall, no fierceness of bite, no violence of rending talons; they love the abodes of men, consort within one home, when they have young nurturing them together, when they fly abroad, hanging side by side upon the wing, leading their life in mutual intercourse, giving with their bills a sign of their peaceful harmony, and fulfilling a law of unanimity in every way.
