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.
