ORIGIN OF THE HANDSHAKE
Ever wondered where handshakes started?
Some even suggest that the up-and-down motion of the handshake was supposed to dislodge any knives or daggers that might be hidden up a sleeve. Yet another explanation is that the handshake was a symbol of good faith when making an oath or promise.
One of the earliest depictions of a handshake is found in a ninth century B.C. relief, which shows the Assyrian King Shalmaneser III pressing the flesh with a Babylonian ruler to seal an alliance. The epic poet Homer described handshakes several times in his “Iliad” and “Odyssey,” most often in relation to pledges and displays of trust.
The gesture was also a recurring motif in the fourth and fifth century B.C. Greek funerary art. Gravestones would often depict the deceased person shaking hands with a member of their family, signifying either a final farewell or the eternal bond between the living and the dead.
