Sand that keeps falling. Illustrations of Hourglasses
Hourglasses with their sand grains have been used for centuries to tell time. The sand in an hourglass keeps falling, without ever stopping or reversing in its course... Time, too, flows without ever stopping or rolling back. Time may not be visible to the human eye, but as you watch the sand in an hourglass drops grain by grain, you will realize the magic of it all--you're witnessing a physical manifestation of time!
Today we are featuring illustrations of hourglasses. Enjoy!
