More Than Just a Greeting: Ancient Roots

While often assumed to be solely a gesture to show an empty, weaponless hand, the handshake's origins are far more multifaceted. One of the earliest known depictions dates back to a 9th-century B.C. Assyrian relief, showing King Shalmaneser III shaking hands with a Babylonian ruler to seal an alliance. This highlights its early role in signifying good faith and solemn agreements, a theme echoed in Homer's epics, 'The Iliad' and 'The Odyssey,' where handshakes often represented pledges and trust. Beyond political pacts, ancient Greeks used the handshake, known as 'dexiosis' (meaning 'to take the right hand'), in funerary art to symbolize either a final farewell or the eternal bond between the living and the dead, particularly evident in 4th and 5th-century B.C. gravestones. In ancient Babylonia, kings would even grasp the hand of a statue of the deity Marduk during the Kassite period (1595–1155 BCE) to symbolize the transfer of divine authority, showcasing a spiritual dimension to the gesture.

From Ritual to Everyday Custom: The Quaker Influence

For centuries, the handshake remained primarily a ritualistic gesture, used for significant events like alliances, oaths, or farewells, rather than a common daily greeting. Its widespread adoption as an everyday salutation is largely attributed to the 17th-century Quakers. They championed the simple handclasp as an egalitarian alternative to the prevailing hierarchical greetings of the time, such as bowing, curtsying, or tipping hats, which reinforced social class distinctions. By extending a hand to everyone regardless of their station, the Quakers propelled the handshake into common use, particularly in America, where it was embraced for its democratic appeal. By the 1800s, it had become so commonplace that etiquette manuals began to offer guidelines for the 'proper' technique, advising a firm but not overly strong grip.

Debunking the Single Origin Myth

A popular theory suggests the handshake originated solely as a way to show that neither party was holding a weapon, with the up-and-down motion intended to dislodge any hidden daggers. While this 'weapon-check' aspect certainly contributed to its symbolism of peaceful intent and can be seen in variations like the Roman forearm grab to check for knives in sleeves, it's a simplification to consider it the sole origin. Historical evidence clearly shows the handshake carrying multiple profound meanings—from sealing sacred bonds and transferring divine power to signifying eternal love and democratic equality—long before its modern ubiquitous usage as a simple greeting.
