How is it that the axis of the earth is not perpendicular to the equator? Why is it raised toward the north and inclined towards the south pole, in a position which does not appear natural, and which seems the consequence of some derangement, or the result of a period of a prodigious number of years?

Is it true that the ecliptic continually inclines by an insensible movement towards the equator and that the angle formed by these two lines has a little diminished in two thousand years?

Is it true that the ecliptic has been formerly perpendicular to the equator, that the Egyptians have said so, and that Herodotus has related it? This motion of the ecliptic would form a period of about two millions of years. It is not that which astounds us, for the axis of the earth has an imperceptible movement in about twenty-six thousand years which occasions the precession of the equinoxes. It is as easy for nature to produce a rotation of twenty thousand as of two hundred and sixty ages.

We are deceived when we are told that the Egyptians had, according to Herodotus, a tradition that the ecliptic had been formerly perpendicular to the equator. The tradition of which Herodotus speaks has no relation to the coincidence of the equinoctial and ecliptic lines; that is quite another affair.

The pretended scholars of Egypt said that the sun in the space ............
