Ptolemaic System, the highly complex system of astronomy ascribed to Claudius Ptolemy, which assumed that the earth was the centre of a sphere which carried the heavenly bodies along in its daily revolution, accounted for the revolutions of the sun and moon by supposing they moved in eccentric circles round the earth, and regarded the planets as moving in epicycles round a point which itself revolved in an eccentric circle round the earth like the sun and moon.
