Memento Mori has been explored in art for centuries. It is a Latin phrase meaning ‘remember you must die’. Common symbols are skulls, hour glasses or clocks, extinguished or guttering candles, fruit, and flowers.
Since it is the season of the spirits, we've included a selection of works that are symbolic, spiritual, mysterious, or 'dead'ly. Happy Halloween!
