Links to Horology Sites It was most likely initiated in the Middle East and North Africa. A clock is defined as a device that consists of two qualities: A regular, constant or repetitive process or action to mark off equal increments of time . Early examples of such processes included movement of the sun across the sky, candles marked in increments, oil lamps with marked reservoirs, sand glasses ("hourglasses"), and in the Orient, small stone or metal mazes filled with incense that would burn at a certain pace. A means of keeping track of the increments of time and displaying the result Relaying the history of time measurement has a degree of inaccuracy, much like clocks themselves. What follows is, if not completely accurate, as close as many researchers can ascertain.

Our present system of timekeeping provides us with a year of fixed and unalterable length which requires only the intercalation of a single (leap) day every four years. We seem to hold the passage of time so securely within the palms of our hands that we can almost hear its quiet heartbeat. Our present calendar has become so accurate that it will take 44,000 years before it falls out of step with the sun by so much as a single day. Pre-industrial societies base their estimate of the year's length on a variety of repetitive occurrences in the natural world. These occurrences include changes in vegetative growth, the phases of the moon, the solstices, and the movement of the stars. Thus the Greek poet Hesiod, who lived in the seventh century BC, advised farmers in Works and Days to begin the harvest when the constellation known as the Pleiades was rising and to begin ploughing when it was setting, but to sharpen their agricultural implements when snails began climbing up plants.
