There’s nothing like it: either the word or the phenomenon. Petrichor is the term coined in 1964 by two Australian scientists, Isabel Joy Bear and Richard G Thomas, derived from the Greek word petra meaning stone and ichor the fluid that flows in Greek gods’ veins (Nature, Volume 201, Issue 4923, pp. 993-995) and they used it to describe the smell of soil when it rains after a prolonged dry spell. They even defined the component parts. Oils from drying plants are absorbed by clay-based soils and rocks and when it rains, these are released in the air along with the aromatic exudations of actinobacteria in the soil.
And that’s what happened here today, spot on 2 pm just when the weather forecast said it would, and after several weeks of drought. I’d just made it back from the allotment where I had been moving raised beds, making new terraces and breaking up compacted soil in readiness for the promised rain. On the way home, draped in emergency polytunnel mac – a somewhat scabby garment I have to say, I noticed how the blossom on the crab apple tree by the garden gate is already going over, and I had only posted its picture the other day, the flowers so pink and freshly unfurling. Today the petals are white and shedding, here and there revealing the makings of miniscule apples on their stems. The procreative imperative in full swing then, which naturally induced a fit of gardener’s panic, a feeling that somehow I was lagging behind. So much to do, and so little time.
But then down came a soft and steady rain that made the garden sit up tall, and pretty soon filled the air with those delicious earth scents, the sort you breathe up your nose and into your soul, that make you one with antique divinities whose veins flow with ethereal fluids. No need to rush. Just breathe. Aaaaah. Petrichor!
