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:
“Foolish prater, What dost thou
So early at my window do?
Cruel bird, thou’st ta’en away
A dream out of my arms to-day;
A dream that ne’er must equall’d be
By all that waking eyes may see.
Thou this damage to repair
Nothing half so sweet and fair,
Nothing half so good, canst bring,
Tho’ men say thou bring’st the Spring.”
—Abraham Cowley (1618–1667)
“A building is akin to dogma; it is insolent, like dogma. Whether or no it is permanent, it claims permanence, like a dogma. People ask why we have no typical architecture of the modern world, like impressionism in painting. Surely it is obviously because we have not enough dogmas; we cannot bear to see anything in the sky that is solid and enduring, anything in the sky that does not change like the clouds of the sky.”
—Gilbert Keith Chesterton (1874–1936)
“Adulthood is the ever-shrinking period between childhood and old age. It is the apparent aim of modern industrial societies to reduce this period to a minimum.”
—Thomas Szasz (b. 1920)
