Undulation Quotes

Wind is a floating wave of air, whose undulation continually varies. (Vitruvius)
The undulation of these infinite numbers of mountains, whose snowy summits make them look as if covered by foam, recalled to my remembrance the surface of a storm-beaten ocean. If I looked towards the west, the ocean lay before me in all its majestic grandeur, a continuation as it were, of these fleecy hilltops. Where the earth ended and the sea began it was impossible for the eye to distinguish.I soon felt that strange and mysterious sensation which is awakened in the mind when looking down from lofty hilltops, and now I was able to do so without any feeling of nervousness, having fortunately hardened myself to that kind of sublime contemplation. I wholly forgot who I was, and where I was. I became intoxicated with a sense of lofty sublimity, without thought of the abysses into which my daring was soon about to plunge me. View quote
Jules Verne
Her hair is troublesome and curly ... It falls in long, black strands, but each strand has a gentle, complicated undulation travelling through it, like a mild electric shock or a thrill, hat gives it a life of its own; it is visually analogous to a tremolo on a musical note. View quote
