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.

De-coding the hidden messages in Christmas carols

Beyond the festive imagery, some carols hint at rebellion and even revolution.

Carols are one of the best loved features of Christmas celebrations and one of the most effective means of spreading the good news of the birth of Jesus, the Saviour of the world. In addition to their clear proclamation of the doctrine of incarnation, that God has taken on human form and come to dwell among us, some of our most popular carols may also have been written to convey further hidden messages.

Take ‘O come, all ye faithful’, for instance. On the surface it seems a straightforward hymn of adoration to the newborn Christ but in fact historians suggest that it may well have been written in its original Latin form, ‘Adeste, fideles,’ as a coded message to rally Jacobites to the cause of Bonnie Prince Charlie on the eve of his rebellion against the British crown in 1745. The man generally reckoned to have been its author, John Francis Wade, was a fervent supporter of the Jacobite cause who seems to have written it while he was plain-chant scribe at the English Catholic college in Douai, France where a weekly Mass was celebrated for the return of the Stuarts to the British throne.

Half hidden Jacobite images, including Scotch thistles and the Stuart cypher, appear in the earliest manuscripts of the carol. Its call to ‘the faithful’ may have had a double meaning and been intended to alert the supporters of the ‘King over the water’ to Charles James Stuart’s imminent arrival in Britain from the continent. Similarly, its reference to ‘Rex angelorum’, translated as the King of the Angels, could also be taken to mean the true king of the English in contrast to the Hanoverian incumbent, George II. In its original Latin form, the carol seems initially to have been sung only in Roman Catholic places of worship, notably in the chapel of the Portuguese Embassy in London and its tune was long known as the Portuguese Hymn.

Another well-known Christmas song may contain similarly coded messages. It has been suggested on the basis of letters from Jesuit priests attached to the English college in Douai, France, that that ‘The Twelve Days of Christmas’ was written to teach the elements of the Roman Catholic faith to children during the period following the Reformation in which it was officially proscribed and suppressed in the United Kingdom. In this reading, the twelve drummers drumming are the articles of the Apostle’s Creed; the eleven pipers piping the faithful apostles; the ten lords a-leaping the ten commandments; the nine ladies dancing the fruits of the Holy Spirit; the eight maids a-milking the beatitudes; the seven swans a-swimming the seven sacraments of the Catholic church; and the ‘five gold rings’ the five wounds of the crucified Christ.

A hidden message of a rather different kind may be lurking in another popular carol, ‘Angels from the Realms of Glory’, which first appeared in a radical Sheffield newspaper entitled The Iris on Christmas Eve 1816. Its author, James Montgomery, the paper’s editor, was twice imprisoned for his support of the French Revolution and reform riots in Britain. The original last verse, which described Justice repealing the sentences of those sentenced to imprisonment and Mercy breaking their chains, was regarded by the authorities as too polemical and subversive did not find its way into any hymn book when the carol was taken up and sung in churches.

A carol with a more overtly contemporary message is ‘It came upon the midnight clear’. Its author, Edmund Sears, who claimed descent from one of the original Pilgrim Fathers, was a Unitarian minister in Massachusetts with a deep commitment to social reform and the promotion of peace. He wrote it in 1849, following the violent revolutions in Europe and the bloody and costly war between the United States of America and Mexico in the previous year. These conflicts were undoubtedly in his mind when he wrote ‘O hush the noise, ye men of strife, and here the angels sing’ and expressed his heartfelt longing for a future age of gold ‘when peace shall over all the earth its ancient splendours fling’, sentiments which we can certainly echo this Christmas.

The German carol Stille Nacht (Silent Night), which regularly tops the list of the world’s favourite Christmas song, underwent several adaptations through the twentieth century expressing the changing political mood in Germany. A Socialist version entitled ‘The Workers’ Silent Night’ which circulated widely around 1900 highlighted the prevailing poverty, misery and distress and ended with an appeal to wake up to social action rather than sleep in heavenly peace. It was considered subversive and banned by the German Government before the First World War. During that war, German soldiers on the front adapted Stille Nacht to express a sense of homesickness and in the period of rampant inflation that followed in the 1920s Weimar Republic a social democratic version asked plaintively: ‘in poverty, one starves silently,/When does the saviour come?’. A 1940 Nazi adaptation turned the song into a celebration of the fatherland and traditional German family values. More recent parodies of the English version have tended to focus on the commercial aspects of the festive season, like the American author Chris Fabry’s send-up of last minute Christmas shopping: ‘Silent Night, Solstice Night, All is calm, all half price’.

The tradition of adapting traditional Christmas carols to contemporary events has a long pedigree in Britain. ‘Hark, the herald angels sing’ has proved particularly appealing to parodists. During the abdication crisis of 1937 a version circulated which began ‘Hark the herald angels sing, Mrs. Simpson’s pinched our king’ and a group of journalists (of which I was one) heralded the birth of the SDP in 1981 with ‘Hark The Times and Guardian roar, Glory to the Gang of Four’. It is rarer to hear parodies of carols nowadays. Perhaps in our troubled times we just want and need to focus on their message of the coming of the Christchild and of God’s kingdom with its promise of a more peaceful and joyful world.
