I want to know the answer to the following question:
What object was assumed to block sunlight during a lunar eclipse?
All the background I'm provided with is that "They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth.". Is that enough to answer the question?
