The term originally comes from the opening lines of the Book of Ecclesiastes in the Bible: ‘Vanity of vanities, saith the Preacher, vanity of vanities, all is vanity.’
Vanitas are closely related to memento mori still lifes which are artworks that remind the viewer of the shortness and fragility of life (memento mori is a Latin phrase meaning ‘remember you must die’) and include symbols such as skulls and extinguished candles. However vanitas still-lifes also include other symbols such as musical instruments, wine and books to remind us explicitly of the vanity (in the sense of worthlessness) of worldly pleasures and goods.
