"Sure, Father," sayd I, "here's Enough that she could affix no Meaning to, nor I neither, without your condescending to explayn it-Cycle, epicycle, nocturnal Rhomb."

The earth was removed from the centre to some other point within the circle; the planet was supposed to revolve in a smaller circle called an epicycle, round an imaginary point which revolved in a circle round the earth: in proportion as observation elicited fresh facts contradictory to these representations, other epicycles and other excentrics were added, producing additional complication; until at last Kepler swept all these circles away, and substituted the conception of an exact ellipse.
