I started wondering about this for no particular reason I can think of. Who’s idea was it? Was it supposed to be symbolic of something? Did they just start passing out pamphlets at rallies titled: “Forget everything you THINK you know about public greetings!”?
nah man. it was invented by the Flavians as a way to pacify Judea. it just got out of hand. get up to date with the cool new conspiracies.
