The Indian garland Japamala
According to tradition, 2500 to 2800 years ago in Northern India, a spiritual student had to say 108 prayers although he didn't know how to count. To help him say all the prayers, his master thought of piercing 108 pimples, passing them on a cord and tie the cord's ends.
Thus was born the tool - garland by which we can do a specific number of prayers without count them.
By this garland the praying man can say a prayer every time he touches a puddle so when the prayer man had touched all the puddles, he knew he had said the right number of prayers.
This garland is considered by folklore to be the first tool to measure a certain number of prayers.
The Indians call this garlad as Japamala
