The body can speak through gestures that are often conscious and sometimes not. Most of the gestures are universal, but some differ by region.
In the greek everyday life the gestures had a special symbolic meaning, which everyone understood and were imitated by other cultures such as the Romans.
In the time of pericles just like today's Greeks, to say no, they would lift their heads back and lift their chin.
When two people met to greet each other, they raised their right hands, it was not customary to greet with a kiss.
The handshake was a solemn commitment, generally reserved for religious acts.
The approval in the theater and in the Assembly has not changed so far, it is manifested with applause and cheers, when it did not like it, whistles and discordant shouts were propagated.
To say that they were happy, they would snap their fingers with their raised hands, while to ridicule or make fun of a person, they would point at it with the middle finger (middle finger, or greater) and the other fingers were bent.
Where more gestures were practiced was in ritualsIn religion, to ward off evil or a bad omen was spit out.
One of the things that the Greeks did not want to show was the sad face, or when they cried, or if they felt that death was approaching they covered their faces with a fold of the dress. They covered their faces out of shame and to avoid showing sadness to others.
