Who first used the forearm handshake?
Answer:
It is impossible to know who first developed this type of handshake or to which culture it is first attributed to, but many have falsely claimed that it was of Roman origin, although this seems to be a belief that was introduced through modern pop culture representations of the Roman world, such as in the TV series Spartacus or the movie Gladiator. There are no specific references to the handshake being used by any particular culture, but it may have been used as a non-threatening symbol that neither member was carrying a concealed weapon.
