They were first described in 1815 by Nathaniel Bowditch, who discovered them through the motion of a pendulum in two dimensions.

Today, stable ones can be obtained on an oscilloscope using two sinusoidal waves with frequencies that are in whole number ratios, and they can be plotted by such formulas y = sin 7t, x = sin 5t. FTP, identify these curves named for a French mathematician.
