Uh-huh. Now for the facts. The "one-finger salute", or at any
rate sexual gestures involving the middle finger, are thousands of
years old. In Gestures: Their origins and Distribution, Desmond
Morris and colleagues note that digitus infamis or digitus
impudicus (infamous or indecent finger) is mentioned several times
in the literature of Ancient Rome. Turning to our vast classical
library, we we quickly turn up three references. Two are from the
epigrammatist Martial: "Laugh loudly, Sextillus, when someone
calls you a queen and put your middle finger out." (The
verse
continues:"But you are no sodomite nor fornicator either, Sextillus,
nor is Vetustina's hot mouth your fancy." Martial, and Roman
poets in general, could be pretty out there, subject-matter-wise.
Another verse begins: "You love to be sodomized, Papylus...").
In the other reference Martial writes that a certain
party "points a finger, an indecent one , at" some other people. The
historian Suetonis, writing about Augustus Caeser, says the
emperor "expelled [the entertainer] Pylades... because when a
spectator started to hiss, he called the attention of the whole
audience to him with an obscence movement of his middle finger."
Morris also claims that the mad Emperor Caligula, as an insult,
would extend his middle finger for supplicants to kiss.
It's not known whether one displayed the digitus
infamis in the same manner that we (well, you) flip the bird
today. In another of his books, Morris describes a variety of
sexual insults involving the middle finger such as the
"middle-finger down prod," the "middle-finger erect," etc, all of
which are different from the classic middle-finger jerk. But let's
not quibble. The point is, the middle-finger/phallus equation goes
back way before the Titanic, the Battle of Agincourt, or probably
even that time Sextillus cut off Pylades with his chariot.
And I ain't kidding yew.
