nostalgia

I’ve always thought this sounds a bit like a medical condition (oh dear, I’ve got a nasty case of nostalgia) and it turns out, I’m right – although it isn’t anything contagious. As you of course know, nostalgia is a noun (person, place or thing) that describes a sentimental longing or affection for the past.

The word itself hasn’t actually been around for all that long. It was coined by a Swiss physician named Johannes Hofer in the late 17th century (1688, to be specific). He used it to describe a medical condition observed in Swiss mercenaries. These mercenaries were a powerful infantry force made up of professional soldiers who served in foreign armies from the late Middle Ages into the Renaissance. Their proven battlefield capabilities made them sought-after troops-for-hire, especially among the military forces of the kings of France. The Swiss Constitution of 1874 banned the recruitment of Swiss citizens by foreign states, and these days there’s only one Swiss mercenary unit left – the nattily-dressed Swiss Guard at the Vatican.

Despite all this military success, when they were fighting away from home, Swiss mercenaries all got terribly homesick (bless them), pining for their beautiful Swiss landscapes. This was the medical condition that Hofer observed – symptoms were thought to include fainting, high fever and even death. Cases were so serious, and led to so many desertions, illnesses and deaths, that the mercenaries were banned from singing the ‘Kuhreihen’, a melody traditionally played by Swiss alpine herdsman as they drove their cattle to or from pasture, in case it pushed the mercenaries over the figurative edge.

After seeing all this extreme homesickness, Hofer combined two Greek words to describe it: ‘nostos’, meaning ‘homecoming’ (the word ‘nostos’ also refers to a theme used in Ancient Greek literature when an epic hero returns home, usually by sea) and ‘álgos’ meaning ‘pain’.

For many centuries, nostalgia was considered a debilitating and potentially fatal medical condition. But by the 1850s, it began to lose its status as a disease, and this meaning had almost completely vanished by the 1870s (although it was still recognised as such in both the First and Second World Wars, mainly by the American armed forces). Nowadays nostalgia is seen as an emotion rather than a condition – a yearning for the ‘good old days’, even if they actually often weren’t that great.

pia

My mum put this down in Words With Friends the other day, which prompted me to look it up as I’d only ever seen it as a woman’s name before and obviously proper nouns are NOT ALLOWED. Well, it turns out we all have a pia – it’s an anatomical term, the full version of which is ‘pia mater’. And it has quite an interesting backstory. (Disclaimer: I’m no biologist, so apologies if you are and I’ve got any of this wrong.)

The pia mater plays a vital role in keeping our central nervous systems healthy and functioning properly. It’s one of three meninges (sets of membranes that provide a protective covering) that surround and protect our brains and spinal cords. The other two are the dura mater and the arachnoid mater. The pia mater is the innermost layer that directly covers the surface of the brain and spinal cord. It’s a thin, transparent membrane that sticks closely to our brains’ contours, following the folds and grooves. It also surrounds the spinal cord.

The pia mater’s primary function is to support, protect and nourish the underlying neural tissues by carrying blood vessels that supply nutrients and oxygen to the brain and spinal cord. If you fall down a lot like I do, then you should be grateful to your pia mater, as it protects that brain and spinal cord from impacts.

We are of course here for the words, so why is it called a pia mater? If you did any Latin in school then you might be ahead of me here – it translates to ‘tender’ or ‘gentle’ ‘mother’ (the word ‘pia’ is the feminine form of the Latin adjective ‘pius’). The name ‘pia mater’ was introduced during the Renaissance period (14th to 17th centuries) when anatomical knowledge was expanding, and Latin was the universal language of science and academia, and has stuck around ever since. It was probably called that because of the way it encloses the surface of the brain and spinal cord, cradling them like a mother. Nice, right?

Oh, and you’ve probably guessed that ‘arachnoid mater’ translates as ‘spider-like mother’, because of its web-like appearance. And ‘dura mater’ means ‘tough mother’ due to this outermost meninge’s durable and robust nature. It’s one tough mother f*cker.
