I admit that I bring this story up when I talk about the Hundred Years’ War – only to debunk it. The version that I tell explains the specific British custom of elevating two fingers as a rude gesture.
The idea being that you need two fingers to draw a bow, which makes more sense, and thus links up a national custom with a triumphant moment in national history! But frankly, I suspect that the French would have done a lot worse to any captured English archers than chopping off their fingers. People who killed their social betters from a distance weren’t very well liked, and would likely have paid with their lives – as did all the French prisoners, archers or otherwise, whom Henry V had executed at Agincourt, in what some historians consider a war crime.
I’m even more suspicious of the alleged transformation of “p” to “f”. First of all, the word “pluck” begins with the blend “pl,” which would logically become “fl” – if the voiceless bilabial plosive “p” has actually transformed into the labiodentalfricative “f,” which is by no means certain. (There is an Indo-European connection between the p-sound and f-sound – see the distinction between the Latin pater and the Germanic Vater/father – but that split occurred a long time ago.) The f-word itself is Germanic with early-medieval roots; the earliest attested use in English in an unambiguous sexual context is in a document from 1310.
And where does the distinction between one and two fingers come from? If the one-fingered salute comes from Agincourt, as the graphic suggests, then at what point did it get transformed into two fingers in England? If the two-fingered salute comes from Agincourt, then at what point was it reduced to one finger in North America? You would think that anything English predating 1607, such as the language, Protestantism, or the Common Law, would have been a part of America’s patrimony….
It seems to me that the single upturned middle finger clearly represents an erect penis and is the gestural equivalent of saying “f*ck you!” As such, it is probably ancient – Wikipedia certainly thinks so, although apparently it became popular in the United States in the late nineteenth century under the influence of Italian immigration, replacing other rude gestures like thumbing the nose or the fig sign. I suppose that the two-fingered salute could still come from medieval archery, even if it didn’t come specifically from the Battle of Agincourt, although the example that Wikipedia links to (the fourteenth-century Luttrell Psalter) is ambiguous. Maybe it means “five” and was a symbol of support for Henry V? 🙂 The fact that Winston Churchill sometimes made his V-for-victory gesture “rudely” suggests that it is of much more recent vintage. What it is supposed to represent I have no idea.
One final observation: any time some appeal begins with “here’s something that intelligent people will find edifying” you should be suspicious. It’s up there with “here’s something that they don’t want you to know.”
