Mnemonic Devices
One of the commonest devices to recall to mind something to be done, is to tie a knot in a handkerchief; the simplest application of knots as a mnemonic device or memory-aid, is in keeping a record of numbers: a historical example is related by Herodotus, iv, 98; the Catholic rosary is a similar mnemonic device.
