Anatolia (Aνατολή), which means East in Greek, which is now modern Turkey, was the heartland of Byzantium before the Ottoman invasion. The Anatolian folk dance called the Horon dance of the Black Sea is the ancient koron-horon, originally of pagan worship which was to become a sacred ritual dance and was performed by men only. Their are many different types of this dance in different regions with the Horon word coming from hur-kor, meaning 'Sun' or horom meaning a line of six or seven corn stalks all tied together to form a lattice... Which looks like people joined together with arms raised.
The Horon is generally danced by a chain of either men or women who form a line or semi-circle. The Horon has one of the most characteristic movements which is a fast shoulder shimmy (tremoulo) and a trembling of the entire body and
sudden squats, which imitates ... or suggests the movements of a fish called the hamsi (a type of anchovy) as it swims in the sea or struggles in the nets for its life. When men and women link arms and perform together as a couple, the dance is often referred to as Rahat, (comfortable horon) which is slower and simpler in its patterns. Horons are danced to music of the cura zurna, cura davul, tulum, kemence, koltuk davulu, and even the accordion.
Many Pontian dances are almost identical in steps to Greek dances. Pontian dances also resemble Persian and Middle Eastern dances in that they are not led, with no
single leader in the dance formation. This is different from Greek dances but is a widespread aspect of Persian and Middle Eastern dances.
Wikipedia states: "The rapid shoulder and upper body movements from the waist is said to have evolved from the modern Turkish version dating to recent centuries. These movement are said to have derived from the shimmying of the little silver anchovy fish (Turkish: Hamsi) found in mass abundance in the Black Sea, which has worked its way into an inseparable part of northern Anatolian culture. As Pontian populations, were exposed to these dances later, it is said that long sea journeys and merchant exchanges, or perhaps throughout the migration of troops as far away as Ireland en route to the Holy Land were also exposed to these dance styles. It is thought the Irish jig and even its modern version, the River Dance, may have its roots from this exposure." (end wiki).
This dance, although somewhat different from its Pagan days is still danced and is recognizable by its music and up-raised arms, Shimmy's and kicks.
