Light does not come from light, but from darkness.

Are not rays of light very small bodies emitted from shining substances?

Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a certain temperature for every colour.

Like a glowworm golden, in a dell of dew, Scattering unbeholden its aerial blue Among the flowers and grass which screen it from the view.
