Vanitas by Pieter Claesz
It is a message that tells the viewer that the pleasure of life only lasts a moment . Because time is limited, live fully the present moment. The symbolism of a skull or rotten fruit remind us of mortality. Musical instruments show the vanity of music; as soon as the music starts, it will die. Music is an ephemeral moment explaining that the return is impossible; it begins and it ends.
