The hasapiko is a Greek folk dance from Constantinople.
Story Telling And Description:
Aivali in 1937: Danced bravely. The dances for weddings were the Turkish, Alivaditikos, and Hasapikos. Hasapikos was danced by two men holding knives. They were also using their hands. Hasapikos was considered to be a difficult dance, one that few knew. Other dances, were danced by both men and women, but hasapiko only by men. During other occasions, such as carnival, other dances were more preferable.
Ikonio in 1948: The wedding ceremony consisted of 3 phases. During the third, Syrtos and Hasapikos were popular but in later years European dances were introduced as well as şarkı (songs) of Constantinople and Greek songs.
Hasapiko took its name from hasapides (butchers) of Constantinople. It is also called Naftiko (navy) near the harbors. It originated in the Middle Ages as a battle mime with swords . A simplified form of the dance is called Syrtaki in France and Zorba’s dance in the movie “Alexis Zorbas”. Initially danced by men only, the leader on the left. In later years, women danced as well. From a stylistic perspective, it can be thought of as a dance of power and precision. The description includes the steps and variations, with foot diagrams. In the rebetiko era, the “slow” dance (hasapikos) was danced by 2-3 close friends (“manges”), so close that they could improvise consistently between them.
