Long before anyone wrote "memento mori" on a mug, people carved the idea into rings, painted it into still lifes, and set it on their desks. The symbols were a way of keeping mortality in the room without having to speak it.
Memento mori symbols are objects and images used to represent the certainty of death and the shortness of life. The Latin phrase means "remember that you must die," and for most of history that reminder travelled as pictures rather than words — because a picture sits in a room and keeps working while you look away.
They are not meant to frighten. They are meant to correct a bias. Left alone, the mind treats time as endless; a skull on a shelf argues quietly with that assumption every time you glance at it. If you want the full background to the idea itself, start with what is memento mori.
Most memento mori imagery draws from a small, stable vocabulary. Each symbol makes the same argument from a slightly different angle.
The skull and hourglass do most of the heavy lifting, but the softer symbols matter too. A skull says you will die. A wilting tulip says something harder to dismiss: the beautiful thing in front of you is on a clock as well.
The skull
The skull is the plainest of the set. It cannot be sentimentalised, and it looks the same for everyone, which is part of the point — memento mori is a great leveller. In memento mori rings and watches, a tiny skull kept the reminder literally at hand, so mortality stayed with a person through an ordinary day.
The hourglass
If the skull points to the destination, the hourglass points to the journey running out. It is arguably the more useful of the two, because it dramatises the present rather than the end. Sand does not fall all at once; it falls now, grain by grain, whether or not you notice. That is closer to how hours actually leave you.
The candle and the extinguished flame
A burning candle stands for a life in progress; a smoking, just-extinguished one stands for a life ended. The candle adds fragility to the picture — a life is not only finite but easily interrupted, snuffed by a draught. The half-burned candle is a favourite because it holds both facts at once: still alight, already shorter than it was.
Flowers, fruit, and bubbles
These are the tender symbols, and they carry the part of memento mori that gets forgotten. Life is not only serious work against the clock; it is also the peach, the tulip, the soap bubble catching light for a second. Their message is not "hurry" but "notice" — enjoy the good thing now, because its schedule is already set.
Because a single symbol goes invisible. Hang one skull on the wall and within a week your eye stops registering it; it becomes furniture. The tradition kept inventing new images — vanitas painters crammed dozens into a single canvas — partly to keep the reminder from fading into the background.
That is the real difficulty with memento mori, and it has not changed. The symbols were always trying to solve a maintenance problem: how do you keep a truth vivid after it stops being novel? Different centuries answered with different objects, but the challenge was constant.
The vocabulary was assembled over a long time from several traditions:
- Roman practice gave us the earliest habit — the servant behind a triumphant general, murmuring that he too was mortal.
- Christian art built the vanitas still life, loading tables with skulls, hourglasses and guttering candles to argue that worldly things are fleeting.
- Stoic philosophy supplied the reasoning: time is the one resource you cannot earn back, so treat each hour accordingly.
The symbols were not owned by any one of these. For a closer look at the faith question, see is memento mori religious. And for how painters turned a shelf of objects into a full argument, see memento mori in art: what vanitas paintings were really trying to say.
The old symbols shared a design goal: make finite time visible enough to change behaviour. That goal still holds; only the medium has moved.
A grid of your life in weeks does what a skull did, more literally — roughly four thousand squares for a full life, most of them already filled in. It is hard to look at and still believe time is endless. A month of graded hours does something similar at close range: one honest sentence per hour, marked green for lived, amber for neutral, red for wasted, until the days fill in with colour you cannot argue with.
The difference from a candle or a bubble is only that the reminder updates. A skull says the same thing forever; a filling-in grid tells you how this week actually went — where the hours were lived and where they were quietly lost. That distinction, lived versus lost, is the whole of the old symbols carried forward. If you want the mortality made concrete, our life in weeks view is the plainest place to start, and the app turns the daily version into a habit.
Whichever symbol speaks to you — the skull, the hourglass, the tulip already past its best — they all say one sentence. The hours are numbered. Knowing it is what makes them worth spending well.
