A leading line, called a "range" in the United States, is a line formed by a pair of marks, which are generally man-made, that are used in position fixing and navigation, to indicate a safe passage through a shallow or dangerous channel. If lighted the marks are called "leading lights" in British English and "range lights" in the United States.
Leading lights are often used in the entrances to harbours or estuaries where there are hazards close to a deep channel.
Also, in art, Leading Lines are lines that guide your eye through the painting or photograph.
Famous quotes containing the words leading and/or line:
“Our leading men are not of much account and never have been, but the average of the people is immense, beyond all history. Sometimes I think in all departments, literature and art included, that will be the way our superiority will exhibit itself. We will not have great individuals or great leaders, but a great average bulk, unprecedentedly great.”
—Walt Whitman (1819–1892)
“Where were you when I laid the foundation of the earth? Tell me, if you have understanding. Who determined its measurements—surely you know! Or who stretched the line upon it? On what were its bases sunk, or who laid its cornerstone when the morning stars sang together and all the heavenly beings shouted for joy?”
—Bible: Hebrew, Job 38:4 -7.
God, to Job.
