This is the amount of axial precession that occurred between the time of Hipparchos and 58 AD. For the Moon, Ptolemy began with Hipparchus' epicycle-on-deferent, then added a device that historians of astronomy refer to as a "crank mechanism":[11] He succeeded in creating models for the other planets, where Hipparchus had failed, by introducing a third device called the equant.
