Why smell jumps the queue when it comes to memories

Smells hardwire deep into the brain, writes Henna Cundill, as she explores why they jump-start such vivid memories.

When I was a 22-year-old undergraduate my mother died quite suddenly. I can't remember the name of the undertakers we used, nor the chaplain who took her funeral. I can no longer visualise what any of their faces looked like. I know I visited the chaplain’s house to plan the funeral, but I can't remember exactly where that house was. What sticks is that the day of the funeral was a sultry summer's day, and both the chaplain and the undertakers smelt of perspiration. To this day there are moments where I catch that same whiff of man-sweat in some other location, and for a fleeting second, I am a bewildered 22-year-old once more. 

Here is another memory. I attended a tiny, rural Church of England primary school in the middle of England. At the end of each school year, all of us donned our little Wellington boots, which smelt faintly of slurry (since this was dairy-farming country) and sweaty feet. Then we lined up in a crocodile and trudged through the bluebell-wood (damp leaves) and skirted the edge of fields (silage, which stings the nose) covering the mile or so between our school building and the village church. 

We would enter the church grounds through the back field, hurrying through an eerily muffled graveyard with tombstones towering far above our heads and the grass disturbingly lumpy beneath our little feet. To the chidings of “Quickly!” and “Quietly!” we children scurried down a gravel path, away from this unsettling place of death, to reach the cool sanctuary of a little church, and the comforting smells (for me, at least) of damp stone and dusty hymnbooks. 

Others may not have the same associations, but for me the smell of dust and damp stone will always cry “safety!” and the reassurance that “there are no ghosts in here!” in contrast to that troubling graveyard. From death to life. Yet, at the same time, getting stuck with my nose close to some man’s whiffy armpit on the Tube will forever insinuate that I am just a child pretending to be a grown-up, out of my depth, overwhelmed with one thousand decisions to make (“What flowers do you want for her coffin?”) and no-one to advise. In the midst of life, death again.  

On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances.

Of course, I am not 22 years old and lost anymore, no matter what that man’s armpit tries to tell me. My rational mind knows better, but my rational mind doesn’t get a say – or doesn’t get the first say anyway. This is because smell is the only one of our senses that bypasses the thalamus (the brain’s ‘filtering gate’ that decides which part of the brain needs to respond to sensory input) and goes straight to the limbic system, where emotional memory is stored.  

Sometimes it is very obvious that this is taking place, such as in the examples given above. On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances. But it can happen in more subtle ways too. Supermarkets infamously pump out smells to influence our buying choices, and we’re trying to sell our house right now, so we’ve been brewing a whole lot more coffee than we ever usually would.   

Intriguingly, scientists don’t really know why the human sense of smell jumps the queue when it comes to cognitive processing. There are biological theories, such as that the smell of predator could wake up our ancestors while they were sleeping and/or could allow them to follow a scent trail quickly when fleeing danger or seeking food. There are social theories too, such as that we don’t have a lot of good words to describe smells, so the brain just doesn’t bother trying to analyse them. Whatever the truth of the matter, the reality is that (whether we like it or not) our noses are an emotional trip-hazard.  

When I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. 

I can’t help wondering what this tells me about my religious practice. Do I go to church because I have made a cognitive decision to worship God each Sunday? Or do I go to church because I am following my nose, getting away from a world full of armpits and responsibilities to a place where I am a seven-year-old girl, all gingham dress and wellies, feeling safe. If so, does it matter?    

Truth is, my mind can give me a dozen reasons not to go to church every single week. In fact, two dozen reasons. More. It has always been a busy week; I’m always behind on work. The house always needs a sort out and the car is never washed. But because certain congregation members are normally counting on me for certain things, and because I’m still pretending to be a grown up, I typically drag myself out the door, and off to church I go.  

And week on week, without fail, when I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. My body registers this before my mind; my shoulders drop a little of their tension. Even if it’s just for a fleeting moment, I start to feel that I know for sure what is absolutely real in my life and what is just pretend.  

Is this knowledge irrational – since it doesn’t come from the cognitive part of my mind? Or is there a God who knows that the cognitive part of my mind sometimes tells me all sorts of untrue and unhelpful things. Is there a God who is choosing to reach out to me in more subtle, more ancient ways?  

I can only wonder if I have been following my nose all this time, without even noticing. Drawn along by an ancient scent trail that leads me time and time again…this way…and that way…until I reach a place where there is safety, and bread.

Pesellino: making the vital visible

Great art doesn’t just delight, it educates. Andrew Davison recalls learning deep wisdom from a child as he reviews the Pesellino exhibition at the National Gallery, London.

Andrew works at the intersection of theology, science and philosophy. He is Canon and Regius Professor of Divinity at Christ Church, Oxford.

The National Gallery

My favourite idol features prominently in National Gallery’s new exhibition of paintings by Francesco Pesellino (1422–1457). I say that by way of provocation: I don’t really think it’s an idol, but that is how it was described to me – by a ten-year-old – in one of the best conversations I’ve ever had as a teacher.  

That was fifteen years ago. I was in the gallery to give a theological tour, as part of a Confirmation class for Westminster Abbey. Half an hour in, we came to Pesellino’s Pistoia Altarpiece. It’s a glorious painting, but I was unconvinced by what it sets out to do, with its dead Christ within a portrayal of the Trinity of Father, Son, and Holy Spirit. The doctrine of the Trinity is about the nature of God, as love and life, and there’s no death there.  

Not that I mean to single out Pesellino for criticism. He isn’t the only painter to represent God that way. Massacio’s version is one of the most significant works of the early Florentine Renaissance, resurrecting linear perspective in painting. Just down the road from the National Gallery, at the Courtauld Institute, there’s a similar painting of the Trinity by Botticelli. They’re all magnificent, I just think that if you’re going to try to depict God, the emphasis should be on life.  

Standing before Pesellino’s painting fifteen years ago, with those misgivings in mind, I asked the dozen or so kids in the Confirmation class what might be wrong with what the painter as trying to do. One child replied instantly: ‘Please Father, it is an idol.’ Dread rose within me. This child was an Arab Christian. Had he, I wondered, grown up in a culture that treated religious art as idolatrous? Had I offended his conscience continuously for the past half hour, with painting after painting? Best to find out. ‘Have the other paintings been idols?’, I asked. ‘No’, he replied. ‘Why not? Why is this one bad?’ His reply came without pause: ‘Because there’s God the Father in it.’ This was getting interesting. ‘So’, I asked, ‘it’s OK to show Jesus, like the other paintings we’ve seen today, but not God the Father?’ ‘Yes’, was his firm opinion. 

These are deep waters, and this was a thoughtful child. To this day, the Orthodox Churches generally forbid depicting of God the Father in icons. Then came one of the most glorious moments of my life as a teacher. ‘Why’s that?’, I asked. ‘Why can we paint Jesus, but not the Father?’ The boy stood silent for some moments. ‘Because’, he said, the cogs of his mind clearly turning, ‘because… because God has made an image of himself in Jesus… You could see Jesus… so you can paint him.’ This was no pre-packaged answer. He was not recycling anything he’d been told before. He was recapitulating the arguments of the Seventh Ecumenical Council (at Nicaea, in AD 787) in real time.  

The eight century was a turbulent time when it comes to religious images. They were supressed in the Byzantine Empire from around AD 730, with a firm condemnation in AD 754. Twenty-three years later, at Nicaea, the church reversed the ban. The decisive argument was formulated by St John of Damascus (AD 675 or 676 – 749): ‘When the Invisible One becomes visible to flesh, you may then draw a likeness of His form.’ It’s the same position as our young theologian in the National Gallery had got to on his own.  

In this way, Christian art rest on Christmas: on the Incarnation, on God’s coming-into-the-flesh. Heir to the Judaic prohibition of ‘graven images’ Christianity – or most of it – made its peace with depicting holy things, and art in churches, because of Christmas, where we see ‘God made visible’ in Jesus. 

In the mystery of the Word made flesh 

the light of your glory has shone anew upon our minds 

that seeing here God made visible,  

we may be caught up in love for God whom we cannot see. 

Those are words from the central acclamation of Christmas (the Eucharistic preface) at Midnight Mass (and at Holy Communion for the rest of Christmastide). ‘Seeing here God made visible’. 

The events of Christmas form one of the two poles of Christian art. Some delightful examples feature in the Pesellino exhibition: a virgin and child and an Annunciation. The other supremely worthy subject for Christian art is the crucifixion and all that surrounds it. As I have noted, in the current exhibition the crucifixion features in his Trinity altarpiece. God’s humanity is most clearly witnessed at the beginning of Christ’s life, and at the end.  

 In the intervening years, I have mellowed towards Pesellino’s painting, and that way of depicting something about God. Painting the eternal reality of God is impossible, but in Jesus we see what we need to see. There is no death in God, but the crucifixion is what God’s life looks like when it is made flesh in a world full of evil. The crucifixion shows God’s embrace of human life to the furthest extremes of suffering and degradation. It shows the life of God overcoming death. We can hold onto what the crucifixion offers in a painting like this one, while remembering that the Resurrection underlines the priority of God’s life over death. One painting can’t say everything.  

Those fifteen years ago, I was aware that I’d been in a remarkable exchange, one that I would not forget. As I found across my time as a curate, children ask the best theological questions. That might be reason to go to see the Pesellino exhibition with a child. Alongside the paintings I have mentioned already, there are also two gloriously child-friendly panels, each showing multiple events from the life of King David. They offer a sort of fifteenth century comic strip, except that the events are fused into one long scene. Pesellino was a master at painting animals. Magnifying glasses are provided to help you search them out.
