selenography

Langrenus was the first to do serious work on selenography, and named the lunar features after eminent men.

The brightest luminaries of earth give names to the dusky spots in the selenography of Helvetius.

For elucidation of this map he wrote a book concerning the moon, entitled "The Universal Selenography."

For many years, accordingly, Schmidt had the field of selenography almost to himself.

Selenography, in the modern sense, is little more than a hundred years old.
