e luminous parts and the mountains, it was at first
proposed to call them after the most illustrious astronomers, but the
fear of giving offense acted as a check on Hevelius and Riccioli,
authors of the first lunar maps (1647, 1651), and they judged it more
prudent to transfer the names of the terrestrial mountains to the Moon.
The Alps, the Apennines, the Pyrenees, the Carpathians, are all to be
found up there; then, as the vocabulary of the mountains was not
adequate, the scientists reasserted their rights, and we meet in the
Moon, Aristotle, Plato, Hipparchus, Ptolemy, Copernicus, Kepler, Newton,
as well as other more modern and even contemporaneous celebrities.

We have not space to reproduce the general chart of the Moon (that
published by the author measures not less than a meter, with the
nomenclature); but the figure subjoined gives a summary sufficient for
the limits of this little book. Here are the names of the principal
lunar mountains, with the numbers corresponding to them upon the map.
