When science meets legend: a dermal melanocytosis that goes on for centuries and goes beyond geographical boundaries. We're talking about Tache Mongolique, also known as the Mongolian spot.
The reality surrounding this skin spot is not limited to pure and simple medical and scientific research. Its presence automatically refers back to the myth. But let's see what it is first.
As numerous clinical studies have made clear, the Mongolian spot is a "dermal melanocytosis congenital in the lumbar sacral region". A simple "spot" of the skin, located in the area of the sacrum, of grey colour tending to bluish, which tends to fade with the passing of time. Its name is due to the fact that about 99% of the Mongolian population is born with this characteristic.
But as we said before, the legend has never abandoned this spot and even today its halo still surrounds it fully. According to the most widespread myth, in fact, the Tache Mongolique is nothing more than the legacy left by Genghis Khan. The famous leader, in fact, in addition to the impressive feats of war, is remembered by the world for his numerous love relationships, which is why each person born with the famous stain would be the descendants of the sovereign.
But Genghis Khan is not the only legend that the Spot carries with it: there are those who speak of a sign left by the Mongols' long habit of riding horses, and those, like shamans, of the sign left by the spirit of the people's grandmother, who first slaps the newborn baby's bottom to open his breath and, in so doing, leaves his delicate mark.
The fascinating thing about this stain, however, is its ability to overcome geographical barriers, and although it can often represent a strong pride in identity (as within Mongolian culture), it is at the same time a clear and direct manifestation of the destruction of ideological barriers created by identity. If it is true that in China, a nation in close contact with Mongolia, the bush is very rare, it is also true that among the Navajos tribes of North America it is present in the vast majority of the population, just as it is no coincidence to find it in subjects far from any historical contact with that part of the world.
Here we can mention the case of the Italian musician and writer Massimo Zamboni and his daughter Caterina, who was born with the Blur after her parents had made a trip to Mongolia. This coincidence led the Italian artist to write a book, entitled "La macchia mongolica" (The Mongolian spot), in which he reasoned about the concept of identity, going so far as to say "Each of us has a clear idea of identity, a small bruise is enough to put our coordinates back into play. Identity can take you far away from your places. I also like the idea of letting it go, identity".
