One of the most famous riddles of all time is the riddle posed by the Sphinx in Greek mythology. It asks, “What walks on four legs in the morning, two legs at noon, and three legs in the evening?” This riddle challenges you to think about the stages of life and the symbolism behind them. The answer, a human, represents the journey from crawling as a baby to walking on two legs as an adult, and finally relying on a cane in old age. This riddle not only tests your knowledge but also makes you ponder the nature of life itself.
