The flush of youth soon passes from the face,
The spells of fancy from the mind depart;
The form may lose its symmetry, its grace.
But time can claim no victory over the heart. [ Mrs. Dinnies ]

Birds, the free tenants of earth, air, and ocean,
Their forms all symmetry, their motion grace,
In plumage delicate and beautiful,
Thick without burthen, close as fish's scales.
Or loose as full blown poppies on the gale;
With wings that seem as they'd a soul within them.
They bear their owners with such sweet enchantment. [ James Montgomery ]

No human face is exactly the same in its lines on each side, no leaf perfect in its lobes, no branch in its symmetry. [ John Ruskin ]

Those who make antitheses by forcing the sense are like men who make false windows for the sake of symmetry. Their rule is not to speak justly, but to make accurate figures. [ Pascal ]
