On the side opposite to them a gigantic conical shadow extended beyond the confines of the ocean of light.

It was the shadow of half the globe of Saturn cast by the Sun across his rings.

Three little dark spots were also travelling across the surface of the rings.

They were the shadows of Mimas, Enceladus, and Tethys, the three inner satellites.

Japetus, the most distant, which revolves at a distance ten times greater than that of the Moon from the Earth, was rising to their left above the edge of the rings, a pale, yellow, little disc shining feebly against the black background of Space.
