Adina Sommer`s Rare Antique Maps and Contemporary Art
|Pierre M. Lapie (1779 – 1850) was a French cartographer and engraver. He was the father of cartographer Alexandre Emile Lapie. Lapie was a Colonel in the French army, where he worked in the corps of topographical engineers. Lapie worked closely with his son and published works together and individually. The work of Lapie and his son was influential on German commercial map makers in the 19th century.|

In Meteorologica Aristotle, wrote that the Greek philosophers Anaxagoras and Democritus proposed that the Milky Way might consist of distant stars. However, Aristotle himself believed the Milky Way to be caused by the ignition of the fiery exhalation of some stars which were large, numerous and close together" and that the ignition takes pace in the upper part of the atmosphere, in the region of the world which is continuous with the heavenly motions. The Neoplatonist philosopher Olympiodorus the Younger criticized this view, arguing that if the Milky Way were sublunary, it should appear different at different times and places on Earth, and that it should have parallax, which it does not. In his view, the Milky Way was celestial. This idea would be influential later in the Islamic world.
Actual proof of the Milky Way consisting of many stars came in 1610 when Galileo Galilei used a telescope to study the Milky Way and discovered that it was composed of a huge number of faint stars. In a treatise in 1755, Immanuel Kant, drawing on earlier work by Thomas Wright,speculated (correctly) that the Milky Way might be a rotating body of a huge number of stars, held together by gravitational forces akin to the Solar System but on much larger scales.The resulting disk of stars would be seen as a band on the sky from our perspective inside the disk. Kant also conjectured that some of the nebulae visible in the night sky might be separate galaxies themselves, similar to our own. Kant referred to both the Milky Way and the extragalactic nebulae, as an island universes, a term still current up to the 1930s.
