Early Modern Period
In the 1670s, the French devised the copper pontoon; after this point, rivers and canals ceased to present significant obstacles. The early modern period in pontoon use was dominated by the wars of the 18th and 19th centuries during which the art and science of pontoon bridging barely changed.

Famous quotes containing the words early, modern and/or period:
“The Americans never use the word peasant, because they have no idea of the class which that term denotes; the ignorance of more remote ages, the simplicity of rural life, and the rusticity of the villager have not been preserved among them; and they are alike unacquainted with the virtues, the vices, the coarse habits, and the simple graces of an early stage of civilization.”
—Alexis de Tocqueville (1805–1859)
“My idea is that the world outside—the so-called modern world—can only pervert and degrade the conceptions of the primitive instinct of art and feeling, and that our only chance is to accept the limited number of survivors—the one- in-a-thousand of born artists and poets—and to intensify the energy of feeling within that radiant centre.”
—Henry Brooks Adams (1838–1918)
“Of all the barbarous middle ages, that
Which is most barbarous is the middle age
Of man! it is—I really scarce know what;
But when we hover between fool and sage,
And don’t know justly what we would be at—
A period something like a printed page,
Black letter upon foolscap, while our hair
Grows grizzled, and we are not what we were.”
—George Gordon Noel Byron (1788–1824)
