Plutarch’s Moralia

The face on the moon

Sec. 929 - note
The first evidence of the moon’s heat was obtained by Melloni in 1846 by means of the newly invented thermophile.

Sec. 934
The apparent color of the moon in total eclipse was as late as the 16th century adduced as evidence that the moon had light of its own, a notion entertained as possible even by W. Herschel.

The principles of cold

Sec. 953

The poets tell us that the Night was born of Earth and mathematicians demonstrate that night is the shadow of Earth blocking the light of the sun.
