Quote (Zachriel @ Mar. 30 2007,13:00) | The movement of the Earth was well-established by indirect observations. Early, direct observations included Bradley's discovery of stellar aberration in 1725, Bessel's measurement of stellar parallax in 1838, and Foucault's pendulum in 1851.

Naturally. (And I bow to your erudition - truly impressive. Should be known as Zachrudition).
But for BlarneyA, these wouldn't qualify as "direct observation." In that world, direct observation of a heliocentric solar system consists in, "see, there's the sun. And over there is a planet oribiting the sun." By that standard, the significance of the precession of a pendulum vis the rotation of the earth is strictly inferential.

I thought not.
