Now is the time where I make the distinction between ancient times and modern times. This distinction is marked by two events which took place in the year of 1609. On July 26 of the year Thomas Harriot, a British astronomer and mathematician, among other things, was the first man to look through a "Dutch truncke", or telescope, at the moon and record what he saw. On July 26, 1609 he recorded his first sketch of the moon. Over the next year and a half he drew another seven sketches and two of what he called "Moon maps." These Moon maps were astonishingly accurate and showed many distinct features of the Moon. Included in these sketches was an outline of the lunar terminator, the dividing line between the illuminated and shaded parts of the Moon.
