Nos jours sont comme l'ombre qui passe (Our days are but a passing shadow) was designed for a school in an area near Montreal where once there stood a vast lake filled with ammonites. Their four hundred million year old fossils are easily found in that region. Students sit in the fossil and run their hands over the impressions of these very old life forms. We are for such a brief moment and these forms give a sense of the immense expanse of time.
